Mononobe Yuu

==Summary==
Mononobe Yuu (物部 悠) is the protagonist of this series, he is a 16-year-old, holding the rank of Second Lieutenant in both Nifl (the misty realm in Norse mythology) and Midgard (the realm of humans in Norse mythology). He sits in seat number 8 in the Brunhild classroom and was born on December 25th. His dragon mark is located on his left hand. 
As the only male "D" in the world, he was originally supposed to be protected in Midgard but was intercepted by Nifl. Consequently, he became a subordinate of Nifl, belonging to the special forces unit "Sleipnir" under the "D" designation, known as the Fafnir. 
It took three years (discovered by Charlotte after two and a half years, followed by half a year of negotiations) before his sister, Mitsuki, utilized her authority to transfer him to Midgard. However, even after coming to Midgard, he still maintains occasional contact with his former superior, Lieutenant Loki (although it is mostly one-sided).

Weapons
After making a deal with Yggdrasil, Yuu was able to obtain blueprints of weapons belonging to the lost civilization of Atlantis by having them downloaded directly into his mind. However, each time Yuu makes a download for additional information, it not only gives him a massive headache, but Yggdrasil also blocks a part of his memories. This problem was rectified when Tear became the new core of Yggdrasil and restored his memories.
*Anti-Personnel Weapons: Weapons that are primarily used to incapacitate humans.
**AT Nergal: An electroshock gun that is used to stun his opponents. This is Yuu's main weapon of choice against ordinary humans.
**Enlil: Anti-armor weapon which fires a high vibration bullet to penetrate through thick armor.
*Anti-Materiel Weapons: Weapons that are designed for use against military equipment.
**AT Ishtar: Anti-materiel sniper rifle.
*Anti-Army Armaments:
**AT Baal: A weapon from in the form of a gunblade for both close and mid range combat, whose cutting edge is one with the barrel.
*Defensive Armaments:
**Uruk 73E: Anti-explosive armament in the form of a large shield.
**Damascus 09P: Anti-material armor in the form of small plates. Used for pinpoint defense.
*Siegfried: Yuu's Fictional Armament, which takes the form of a large-caliber ornamental gun. It is capable of firing Dark Matter as bullets, which Yuu transmutes into any matter and shape he wishes. However, Siegfried is only able to fire 3 bullets before losing its shape and needing to be re-constructed again due to Yuu's low dark matter capacity.
Anti-Dragon Armament, Marduk: A series of weapons used mainly for anti-Dragon combat and manipulated through a mental link. However, due to the massive amount of memories taken from him, Yuu tends to sever his link with Yggdrasil before finishing the download of their blueprints, leaving most of these weapons in an incomplete state (although, according to Yuu, their power is not enough to defeat Dragons even in their complete state). Due to being incomplete, these weapons eventually malfunction and self-destruct after use. The weapons also require a substantial amount of space and secure footholds to be used effectively due to their enormous size. In order to construct anti-Dragon armaments, Yuu must borrow dark matter from another D due to his low capacity and the enormity of the weapons. Another downside is that using these armaments completely drains Yuu, leaving him unconscious for a while. According to Atla, pilots that have mental links with Marduk are called linkers.
*Deus Dragon, Marduk: Described as the second calamity's ultimate trump card, Marduk's true form is revealed to be a massive battleship roughly two hundred meters in length. The ship's body is covered with silver-white armor with grooves, tracing out a network of geometric patterns reminiscent of pulsating blood vessels, brightening and dimming in periodic cycles. Furthermore, all the other anti-Dragon armaments that were previously summoned by Yuu are mounted throughout Marduk's body. The ship is capable of flight even in space by using the variable-sweep wings on the sides as gravitational control devices. Yuu is connected to the ship via mental link, which provides him with a full grasp of the entire ship's capabilities and absolute control over it. However, the strain of manipulating such a massive and complex weapon causes intense headaches to him. Yuu first summoned the complete form of Marduk in Volume 12 after Tear supplied him with the remaining data through her connection to the Akashic Record, while every D on Midgard continuously supplied him with enough Dark matter to materialize it due to its enormous size. According to Atla, Marduk requires at least two linkers to control safely.
Megiddo Anime.png|Megiddo
**Special Artillery, Megiddo: A large cannon that fires a bullet of blue-white light, causing everything caught in its blast to disintegrate on the atomic level. Megiddo is even able to reach the dimension where the true body of Vritra lives and inflict damage on it. It was first used by Yuu during Hekatonkheir's attack on Nanato City, although its full name was revealed in Volume 2. After completion, the Marduk battleship contains a total of two Megiddo cannons.
**Main Cannon, Babel: A giant cannon with a split barrel and a lens-like device in the middle. Babel fires a super-gravitational singularity in the form of a black torrent that tears space to crush everything existing within the range of its attack. It was first used by Yuu in Volume 1 to counter Leviathan's Anti-gravity. As the main cannon, in its complete form, Babel protrudes from the prow of the Marduk battleship.
**Psionic multi-barreled cannon, Noah: A double-barreled artillery on a rotating turret. Noah is a weapon designed for amplifying and firing the gunner's thoughts, causing a slight amount of ether particles to materialize under the influence of the compressed mental waves, thereby obtaining the power to interact physically with them. Other people can also transfer their thoughts to the gunner by utilizing the same principle as dark matter transfer, thus increasing Noah's power. Unlike other anti-dragon armaments, this weapon was in an almost complete state upon materialization due to its small size, allowing multiple copies of it to be constructed. Yuu used it for the first time in Volume 4 to defeat Hraesvelgr. Upon completion, the Marduk battleship contains a total of eight Noah multi-barreled turrets.
**Hyperspace Reversion Rocket-assisted artillery, Abyss: A gigantic missile pod in the shape of a rectangular box, which contains a large number of missiles. Abyss is a disintegration weapon that forcibly creates hyperspace that is not supposed to exist at the same spatial coordinates, thereby causing the world's corrective force to erase everything at those points together with the surroundings. Due to its sheer size, it requires dark matter from several Ds in order to materialize it. Yuu used it for the first time in Volume 10 after receiving data on its specs from Tia, who was connected to the Akashic Record, in order to eliminate all traces of Charlotte's blood mist from Midgard. In the completed Marduk battleship, the missile pods of Abyss are located behind the bridge.
**Light Shell Barrier, Eden: A shield of light created by multiple small units. The configuration of the barrier can be changed to either surround the entire ship or protect specific parts. There are restrictions on the number of times it can be used and its active duration, but its defensive power, when combined with multiple wind barriers created by Ds, is strong enough to completely block 'Eternal Longevity' Bahamut's attacks.
Intelligence: Genius in Assassination (Yuu was trained to become the strongest Assassin in the world, ultimately even surpassing Major general Loki, who has highest amount of cold lost) 
Weaknesses: None 
Notable Attacks/Techniques:
*Plasma Bullet: A bullet made of plasmafied compressed air. It has enough power to pierce through diamond with ease.
*Air Bullet: Yuu fires a bullet of air that can be used to push himself further up into the sky.
*Air Pressure Bullet: Yuu fires an Air Bullet at a higher pressure, creating an explosion of air perfect for cushioning impacts.
*Cage Bullet: Yuu fires dark matter that is transmuted into a small metal cage to trap his target.
*Red Bullet: Using what little amount of dark matter is left in Siegfried, Yuu transmutes it into a high-temperature blade of air by compressing air into the shape of a knife.
*Smoke Bullet: Yuu transmutes dark matter into smoke. This is mostly used for smokescreens and to dissipate Dark Matter generated by an opposing D.
*Nitro Bullet: Creates a large volume of nitrogen to produce a gust of wind that can blow away fire.
*Anti-Gravity: Upon defeating Leviathan, Yuu inherited its Authority, Code Vier. This enables him to generate repulsive fields that can negate gravity and reflect incoming attacks by converting his dark matter into anti-gravitational matter. Yuu can also apply these capabilities to the bullets of the weapons he creates. However, he is unable to bring out power on the level of Leviathan. In Volume 13, while facing the core of 'Heavy Tremors' Nova in the form of Miyako Shinomiya, Yuu was able to bring out the Authority's full power by growing a horn on his forehead through partial draconification.
**Half Gravity: An alternate form of Anti-gravity, in which Yuu fires a bullet that halves the weight of the target.
**Gravity Zero: A variation of Anti-gravity, which temporarily disables gravity in a certain area.
**Gravity Grave: Another variation of Anti-gravity that uses two repulsive fields to distort space and shoot it as a projectile.
*Ether Wind: After defeating Hraesvelgr, Yuu inherited its Authority, Code Drei. This enables him to generate golden particles capable of manifesting the souls of sentient organisms and immobilizing living beings by transmuting his dark matter into Ether Wind. He can also hear the thoughts of other people and enter the depths of their consciousness using Ether Wind. Yuu can fire these particles through the weapons he creates. However, similar to anti-gravity, Yuu is unable to wield power on the level of Hraesvelgr. In Volume 10, Yuu fully utilized Ether Wind after nearly being killed by Loki, materializing his spirit to envelop his body and allowing him to move using his mind alone. In this state, Yuu becomes immune to any form of physical interference, and his reaction time and reflexes are heightened since the process of transmitting orders from the brain to the muscles is skipped. In Volume 13, Yuu demonstrates the ability to form weapons using Ether Wind, much like a Fictional Armament.
*Code Lost(Fafnir): A portion of the scrapped Authority of 'Colorless' Fafnir, which is implanted into Yuu by Loki, allows Yuu to enhance his senses and adaptability to kill anyone as long as they are in the same form as Yuu. He can cause deaths just by imagining the manner in which they will die, by interfering with the Law of Causality. Once the enemy is killed using Code Lost, it's absolute death, and can't be overwritten. Even if the opponents have healing factors or immortality, it will be negated in the name of absolute death done by Code Lost. This is irreversible. The concept of distance also becomes irrelevant to its users. By manipulating causality, he can also make any attack struck at him miss, and any attacks he makes will absolutely hit their target. The fate of the opponents will be in the hands of Code Lost as soon as the match starts.
*Shamash(9th Authority): Yuu's Authority as a Counterdragon. By utilizing it, Yuu can give shape and form to End Matter through his voice. This enables him to restore the original form of those consumed by the ninth calamity's darkness, as well as seal End Matter within an individual by defining it as that person.
