Arthur's Celestial Spirit Magic

**Celestial Spirit Magic** (星霊 魔法, Seirei Mahō): Arthur practices Celestial spirit magic. Celestial Spirit Magic is a Magic in which Arthur summons Celestial Spirits by opening their gates through the use of Celestial Spirit Gate Keys. These Keys are separated into two classes: the more common Silver and Elemental Keys and the rarer Gold, Platinum and Crystal Keys. Keys for Celestial Spirits are counted in Units (collectively without regard of Crystal, Elemental, Gold, Platinum or Silver), and a Celestial Spirit Mage is noted by how many Units they have obtained.

When a Celestial Spirit Mage receives a Key and opens its Celestial Gate for the first time, they have to set up a contract with the respective Spirit. This contract consists of asking the Spirit which days it can be summoned by its contractor. This simple agreement leads to a dedicated and serious bond between the Spirit and summoner. However, under certain circumstances, i.e. during battle, and a Spirit is summoned for the first time, the making of a contract may be suspended on a later date. Contracts can be broken if the Mage gets arrested, releases the Spirit by themselves, or dies. When a Celestial Spirit Mage summons a Spirit, it appears directly next to them, as that's where the gates to the Spirit world had been opened. It's impossible to summon spirits elsewhere.

The Spirits must also abide by certain rules enforced by the Celestial Spirit King. The only rule that has been introduced so far is that a Spirit may not directly or indirectly kill its summoner under any circumstances. When the Gates are closed, it is required from both the summoner and the Spirit to agree upon the gate's closure. However, Spirits can also be "forced closed" in battle, which means they can be forced back into the Celestial World by the summoner's will, though not every Celestial Spirit Mage is capable of doing such. Celestial Spirits also have different categories of sorts that fall under the basic summoning conditions from their owner. It also seems that if the Celestial Spirit is strong enough, they can employ their own Magic to stay in the Human World, if/when the contract is not in action. The strength of the Celestial Spirits is affected by the Magical strength of their summoner.

Arthur, practicing this magic since he was still a small child, is quite adept to Celestial Spirit Magic, some may even call him a grandmaster of the said magic as well, due to a large amount of units he has collected, as well as mastering techniques such as Urano Metria and Gottfried. He also found a way of utilizing this magic to a greater extent, making it highly more efficient and reliable in combat. It seems like Arthur had found a way to utilize Celestial Spirit Gate Keys as a type of medium capable of channeling Celestial Energy directly from Celestial Spirit World, allowing him to use magic without any costs.

* **Summon** (召喚, *Shōkan*): A Celestial Spirit Mage is able to summon Celestial Spirits from another dimension by using the Keys of the Gates. Upon summoning Celestial Spirits, the keys radiate a golden or green light from which the respective spirit is formed. Celestial Spirits can aid the Mages in battle, do chores for them, or even just play with them. However, the mage has to follow the contract they have with the spirit and can summon them only on certain days. However, if the bond between the mage is strong enough, the contract can be temporarily dissolved.
	+ **Enhanced Summon** (強化召喚, Kyōka Shōkan, lit. Improved Summoning Procces): A special summoning technique known to just a few of the Celestial Spirit Mages, Enhanced Summon allows a celestial spirit mage to pour a small portion of his magic into the key upon the regular summoning ritual, thus empowering the said spirit to a great extent. This empowerment usually manifests itself in form of a physical empowerment, most likely giving the repsectivie spirit an armour of some sort, or even a weapon. It has to be noted that most of the spirit who don't usually appear in a humanoid form will get it with the help of this technique. It has to be noted that this technique doesn't interrupt the Double Gate Opening, allowing Arthur to power up certain spirits to the strenght equal to one of an average S-Class mage's, but rarely chooses to do so, relying in the variety of spirits rather than n extremly powerful one.
	+ **Spell-Summon** (技術-召喚, *Gijutsu Shōkan*): A Celestial Spirit Mage may be able to summon fort a specific spell or technique used by the spirit of their choice. By channeling a small portion of their magical energy via the key itself, Arthur connects with the respective spirit on a mental level and asks for their assistance, naming the preffered technique he would like to utilize. As a response, the spirit preforms the requiered spell and releases it through the minorly cracked gate, big enough for the energy to burst out. This ability grants Arthur more choices in battle with low magical power. Arthur has even demonstrated the ability to merge several attacks or even a Celestial Comet into a powerful one capable of knocking down a wall.
	+ **Sacral Summoning** (仙骨召喚, *Senkatsu Shōkan*): This spell is available only to celestial spirit mages who have gathered both, Northern and Southern Crown Gate Keys. By putting the keys in front of himself, Arthur is capable of starting this unique summoning process. Upon colliding, the tips of the keys will glow bright gold and separate slowly, creating several thick strings of pure celestial energy that keep twisting and bending one ofer another as they form a magnificent large circural sigil with five minor ones with the same twisting pattern, each one of it having one major string that connects the smaller sigils to the bigger one. The mentioned creation is roughly 120 cm high and appears to be levitating in front of Arthur. The two platinum keys can be seen pointing north and south at the poles of the sigil. By putting any type of key in the sockets of the minor sigils, Arthur is able to summon five spirits at the same time. As the energy within the sigils is Celestial Energy, the energy cost for Arthur while preforming this spell is equivalent to the one of opening two silver gates, Southern and Northern Crown. Reffering this ability as his true last resort, Arthur only uses this technique when he needs to overwhelm his opponent through strength in numbers. After every summoned spirit's gate is closed, their respective keys appear levitating at the same spot they were lastly seen while the Crowns' keys get closer and connect once again, this time with no magical effects.
	+ **Double Gate Opening** (二重召喚, *Nijū Shōkan* *lit. The Second Opening of the Cracked Gate*): As the name suggests, this technique allows Arthur to open an already existing gate for the second time in order to manipulate the existing gate's properties, or better said, this technique allows Arthur to alter the modifications of summoned spirit to a limited extent. In order to access such a feat, he must first get a verbal or mental of the spirit that is about to get a boost. If the said spirit were to deny the alternation for any possible reason, the energy used for the second opening goes to waste. This modification usually manifests itself in form of a weapon or armour, that is, on a physical level. However, on several occasions, the modification happened on a phychological level, purifying the spirit and pulling them from a trance they were in. On extremely rare occasions, the modification manifested in form of rejuvenation, that is, it instantly healed the spirit from all injuries, as if they were just summoned. It should be mentioned that a gate can be opened for the second time only once during the spirit's continuance on Earth Land. If Arthur were to open the gate for the third time, the key would simply shatter.
	+ **Regressed Summon** (退縮召喚, *Taishuku Shōkan lit. Miniature Gate Opening*): Regressed Summoning technique, as the name suggests, allows Arthur summon a miniature, chibi-like version of the respective spirit. The whole summoning process is identical as if Arthur were summoning the respective spirit through the original process. A spirit in this form is, however deprived of techniques such as Enhanced Summon and Double Gate Opening. As a return, their existing telepathic abilities are augmented to an extent where the spirit is capable of communicating with mages other than Arthur freely. The spirit keeps all of their abilities, although they are corresponsive size. In addition, while in this state, every spirit is granted the ability to levitate, as well as to enter a willow-o'-the-wisp shape, the colour of which is corresponsive to the spirit's nature.
* **False Summon** (召喚, *Nise Shōkan*): A rather simplistic spell distinct only to the Moshiyoto Family, False Summon technique was developed in order to allow a celestial spirit mage to have more units on the battlefield with less magical energy input. As the name implies, this summoning technique allows Arthur to *falsely* summon a celestial spirit, or better yet, a **Celestial Pawn** (天の質屋, *Ten no shichiya,*lit. *Lesser Celestial Being*) who is capable of taking numerous appearances, suitable for the required situation. The whole *summoning* process can be broken down in two phases; the first phase starts when celestial spirit mage starts channeling their magic througout a Zodiac Spirit Gate Key (although, on several occasions, crystal spirit gate keys seemed worked as well) and transforming the input energy into celestial one, releasing numerous golden orbs from the key's blade, forming a golden anthropomorphic blob made purely of celestial energy. The second phase works in a manner similar to the one of a molding magic and it starts the moment the celestial energy is released from its medium. The process is rather simplistic in its nature, but requires a lot of concentration in order to be done properly. After approximately five seconds, the golden blob starts to shift into whatever Arthur previously desired. The Celestial Pawns usually have an angelic-like appearance, having magnificent golden wings sprouting from their backs and more often than not, a halo. A Celestial Pawn appears to be rather skilled in hand to hand combat and is capable of dueling Arthur himself on their own. The said being ~~always~~ usually takes a rather feminine appearance because, as stated by Arthur, it's easier to conjure a female pawn due to their predetermined physique. There doesn't appear to be a limit to how many pawns each key has conjured, although, so far, the maximum number of pawns conjured from a single key is five. After a key is used for this summoning method, Arthur is unable to *actually* summon its respective spirit for three minutes, with additional two minutes for each pawn conjured. The said pawns are furthermore unable to move 15 meters away from the key used to conjure them.
	+ **Enhancement** (強化, *Kyōka*):
	+ **Multiple Summons** (複数召喚, *Fukusū shōkan*):
	+ **Upgrade** (上り坂, *Noborizaka lit. Advancement*):
		- **Knight** (桂馬, *Keima*)
		- **Bishop** (書く, *Kaku*)
		- **Rook** (飛車, *HIsha*)
* **Multiple Summons**(複数召喚, *Fukusū shōkan*): Summoning more than one Celestial Spirit uses up a lot of the summoner's Magic ability which may cause death. However, Arthur has demonstrated the ability to summon four crystal spirits and one silver at the same time, that being five in total (not including Sacral Summoning technique). Considering the fact that Arthur is capable of this feat, it provides him great flexibility as he is able to combines the strength and abilities of their spirits for more powerful attacks.
* **Force Gate Closure** (フォース·ゲート閉鎖, *Fōsu gēto klōsa*): Arthur is able to force the gate of a Celestial Spirit to close against their will, forcing them to return to the Celestial Spirit World. Such skill would come in useful if one of his Spirits had been taken over by the foe through various means and was fo,rced to attack him, allowing Arthur to remove them from battle without actually harming them. For a Celestial Spirit Mage, obtaining this ability seems to be a remarkable feat.
* **Stellar Projection** (恒星投影, *Kōsei tōei*): Upon channeling his own magical energy throughout the key, Arthur converts the ethernano coating the key's stem into Celestial Energy that starts accumulating around the key. The said celestial energy then begins to envelop the stem, expanding up to ten times while doing so, shaping itself exactly like the stem, literally projecting the key in front of Arthur, hence the name. The said energy than begins to harden and starts acting as a weapon. In order to maintain the energy, Arthur doesn't have to keep the flow active, the key rather does it itself. Upon breaking, the key will expell more celestial energy, immidiately fixing the made damage.
* **Celestial Jewel** (天の宝石, Ten no hōseki)
* **Sideris** (サイダース, *Saidārusu*): By pointing a Golden Gate Key at his desired target, Arthur is able to release several golden orbs that orbit around him until they stop three feet above him, creating a miniature constellation that rotates around itself slowly. Upon summoning the orbs Arthur has to recite "*I ask for your assistance, oh great stars that are in heavens, show me your appearance!*" Each one of them being made out of pure Celestial Energy, this construction has high destructive potentional. Usually, each one of them fires a powerful laser beam at the desired target. However, on several occasions, the constellation began to lower itself and dissolve while leaving a golden trail around Arthur, forming a golden-glowing sphere that can act as a make-shift shield. The said barrier dissapeares within 10 minutes if not damaged, but is able to withstand quite an amount of damage, as seen during his battle with Satoru.
* **Tesentis** (魔れ複, *Tesenutisu*): By pointing any type of a gate key towards the desired target, Arthur is able to fire up an enormous amount of Celestial Energy shaped like a laser-beam at his opponent. The ray of energy is said to have a high destructive capacity, being able to pierce through most types of metals and even create holes in walls. The colour of the beam varies from the colour of the key, a godlen one producing a golden ray, silver one producing a silver ray etc.
* **Celestia** (セレスト, *Seresutia*): By pointing any type of a gate key up in the sky, Arthur is able to release an enormous amount of Celestial Energy that glows golden and surges around Arthur, hardening as it reaches a state of a perfect sphere that keeps orbiting around Arthur, deflecting most of the magic-based attacks heading for Arthur. The shield can easily be broken my sheer power and any type of physical damage, such as hitting a wall or getting slashed by a sword. Unless destroyed, this creation will orbit around Arthur until he commands it to dissapate.
* **Protection of the Stars** (星の保護, *Hoshi no hogo; lit. The Ultimate Protection of the Night Sky*): A very special and unique technique developed by Arthur himself; this spells seems to allow Arthur to become invincible, figuratively speaking. By combining two of his defensive abilities, Celestia and Sideris, Arthur easily creates  two goldens spheres orbiting around himself. As the two make contact, they combine in a single seemingly larger barrier that can hold up to two people, Arthur and another person of his choice. The said barrier can withstand both magical and physical assaults, acting as the ultimate defensive spell perfect for both close and distance fights.
* **Celestial Comet** (天上の彗複, *Tenjō no suisei*): A technique created by Arthur himself, this is considered to be the only spell not involving celestial spirits, both directly or indirectly. Arthur has referred to this spell as a weaker form of Urano Metria, as the two spells have some similarities. The only requirement for this spell is a key, regardless of what kind, though Arthur prefers to use Golden Keys, mainly due aesthetic purposes. By simply moving his hand forwards while holding a key in it, Arthur is able to fire a wave of pure celestial energy from the Celestial Spirit World. This ability does not require great skill and thus doesn't consume much energy, making it a highly desirable skill. The wave itself is shaped like a sphere and is constantly spinning, additionally increasing its already high speed. So far, Arthur has demonstrated the ability to fire more than one Celestial Comet, making this a highly versatile ability. The colour of the wave depends on the colour of the key, thus silver keys will produce silver energy, crystal light blue etc. Upon colliding with the target, the sphere will combust, creating a massive explosion, powerful enough to break down a large thick wall.
	+ **Seven Shooting Stars of Heavens** (天七つの流れ星, *Ten nanatsu no nagareboshi*): A stronger variation of Celestial Comet; as the name suggests, Arthur conjures seven Celestial Comets simultaneously from two Golden Gate keys, one in each hand. He fires the first six normally, but uses both keys in order to conjure up a much larger sphere, roughly double the size of the original Comet. The Comets will start orbiting around the target, all attacking it a second before the final comet collides with it, dealing a massive amount of damage to the target and the surrounding area. The energy required for this spell isn't high, so Arthur can perform this spell and still be able to use other abilities.
* **Celestial Unison Raid** (合体魔法・星霊流, *Seresutiaru Yunizon Reido)* : Celestial Unison Raid is a spell exclusice to Celestial Spirits, alongside their owner. Like all Unison Raids, Celestial Unison Raid synchronizes magic of two or more spirits in order to create a more powerful and efficient attack, such as combining Gladius' Stella Cadens and Arthur's Celestial Comet, then allowing Taurus to absorb it with his labrys and use it as a projectile of his own.
* **Celestial Fire** (天の火, *Ten no Hi*): An ability developed by Arthur himself, Celestial Fire can be classified as a caster spell with defensive and supportive properties. To execute the spell, Arthur first summons  nine keys, three golden, three silver and three crystal ones. Each set of keys then begins to levitate around Arthur on different levels. Each one of the key starts to glow and release some celestial energy, coloured correspondingly to their key type. The said energy then shapes itself into a ribbon and connects to the other two keys, forming three triangles around Arthur. The said triangles then transform into three celestial glyphs that pass through Arthur. By chanting "*I call the light of golden rays I seek protection thus’, I pray. For heavenly forces at my side, oh be my spirit guides who walk with cunning skill! Come to my aid! Come at my will!*", the said glyphs make a projection ten feet above Arthur that starts to emit celestial energy downwards, creating a forcefield around him. The energy within starts to coat Arthur and rapidly enter his body, replenishing his energy and healing his wounds. The shower of celestial energy lasts for about ten seconds. The glyphs disappear alongside their projection, leaving nothing but nine keys levitating above Arthur.
* **Celestial Beacon** (天の烽火, *Ten no Hōka*):
* **Telepathy**:(テレパシー, *Terepashī*): Due to very strong connections with his spirits and being on the same wave-length, Arthur is capable of communicating with each one of his spirits, regardless of their position (summoned or in Celestial Spirit World). He is able to do this via their keys, by simply putting his hand over the key's bow, although, on several occasions, with a spirit he has the biggest connection with, Arthur was able to communicate without putting his hands on the key. He has shown to be able to communicate with up to four spirits at the same time and frequently uses this skill, mainly for tactical maneuvers or checking if they're alright in case they were injured during a battle and were forced to return to the Celestial Spirit World. In case he replaces a spirit, Arthur wouldn't be able to communicate with the respective spirit until their connection is broken.
* **Catalogue Book** (目録本, *Mokuroku hon*): Human version of Star Memory A technique known to just a few celestial spirit mages; This is not a spell per se, but it's rather a form of a magical artifact filled with knowledge. The book is said to be able to contain and store celestial spirit gate keys and allow only the rightful owner to summon it, either via Requip or by flipping throgh the pages, as the two (Requip and the book) are connected, sharing the same miniature dimension. This item allows Arthur to freely store his books and find out informations about random spirits.
* **Urano Metria** (ウラノ・メトリア, *Urano Metoria, lit. The Ultimate Magic of Stars*): A very powerful spell exclusive to Celestial Spirit Mages; Just like Gottfried, Arthur had discovered this spell in an old book and this particular spell caught his eye. This magic is one of the rare caster-type spells available to Celestial Spirit Mages, thus is highly desirable and more available than Gottfried, due to its usage during the X791 Grand Magic Games. Just like Gottfried, Urano Metria requires the user to chant an incantation in order to use this technique, but the spell itself doesn't inflict pain to the caster. While performing the incantation, Arthur spreads his arms and raises his head, looking at the sky as he remains unable to move during the chanting process. The incantation is "*Survey the Heavens, Open the Heavens... All the stars, far and wide... Show me thy appearance... With such shine. Oh Tetrabiblos... I am the ruler of the stars... Aspect become complete... Open thy malevolent gate. Oh 88 Stars of the heaven... Shine! Urano Metria!*". As a result eighty-eight constellations bestowing their power upon the magician- the magician aims at their unfortunate targets, as the visage of countless star-like lights make their appearance within the vicinity, followed by a shroud of darkness blanketing the area. These stars gather and converge all sorts of energies upon their forms before each star detonates in a rather spectacular manner, catching the user's target(s) in the blast range no matter what they do to evade- as each star will follow the target(s) to the ends of the earth like a heat-seeking missile, ensuring that the magical energy spent is not in vain.Upon contact with the enemy, the explosion of all eighty-eight stars released in the form of a tremendous attack provokes the obliteration of the enemy from the inside out in a very violent manner, more often than not propelling the victim into the air or anything in the vicinity by the sheer force of the blast. The force of the blast is enough to pulverize any magical weapons and armour, as well as eradicate any magical auras. To the on-looker and also the victim the move would appear as if a myriad of stars came crashing into them provoking a massive galactic explosion with visuals giving the indication of a second Big Bang occurring, all converging upon the unlucky target. Urano Metria packs enough strength to defeat almost any demon; including an Etherious.
* **Gottfried**(ゴットフリート, *Gottofurīto*): A long forgotten magic that is only available to highly skilled Celestial Spirit Mages; While clearing the library in the abandoned academy building outside of Magnolia, Arthur has stumbled upon a book exclusive to Celestial Spirit Mages with a seal on it that allowed only those of the purest heart to open the book. The book itself contained a lot of information that was already available to him, but one spell caught his eye, a super magic, long forgotten and could be considered a taboo for its effects. To activate the spell, Arthur must kneel on the ground and hold his hands up, pointing to the sky while reciting the incantation. Whilst chanting, a green aura will encase him, acting as a shield as it surges towards the desired target while stars slowly fill up the heavens. Upon saying the incantation, any summoned spirit will be forcibly sent back to Celestial Spirit World. While performing the incantation, Arthur will be inflicted by incredible pain, equivalent to the pain dealt to the target. The incantation Arthur has to say is "*I ask that the heavens make the stars descend to earth. Illuminate... by all means... this land... this world... this land! By your hand, let everything be illuminated. Twinkling, shooting, falling... Let the stars descend before us! Gottfried!*". So far, Arthur hasn't used this spell on anyone because of his morals, but if necessary, he will perform it. Also, this spell highly drains Arthur, making him unable to use any magic for a short period of time.
