Holy Magic

**Holy Magic** ｢神聖魔法, *shinsei mahō*｣ is a type of Spirit Magic, requiring a contract with a Holy Spirit or God. For the purposes of Holy Magic, any being capable of manipulating Spiritrons is sufficient as a God. Despite being a form of Spirit Magic, it is considered one of the four main Magic types.

## Principles

For a person to use Holy Magic, they need to form a "pact" with a god or be a god themselves. The condition to learn Holy Magic as a believer is simply a heart that believes in miracles. This is known as **The Power of Faith** ｢信仰の力, *shinkō no chikara*｣ that turns their strong thoughts or feelings into power, making it accessible to even Monsters and Daemons. Once a pact is created between the god and believer, the believer uses their god's "Name" as a medium to open a Soul-based channel between the two, offering Magical Power in exchange for the god's assistance.

On the god's end, since there's no way to assist many people at once, they link together and borrow the cumulative calculation power of their believers to share the burden of putting the Magic together. Since the burden placed on the user is low, the resulting holy magic's strength depends almost entirely on how much "faith" the user has in their respective god. The stronger the believer's "faith" is, the stronger the connection between the two is, and as a result, the stronger the magic becomes.

This system as a whole is collectively referred to as the **Secret of Faith and Grace** ｢信仰と恩寵の秘奥, *shinkō to onchō no hiō*｣.

## Usage

Holy Magic can be split into two distinct categories based on the type of power being borrowed from/used by the respective god.

### Basic Level

Basic-Level Holy Magic makes use of Holy Power that can purify Magicules and heal wounds. While its offensive options are minimal and don't work very well against regular beings, against Monsters and especially Undead, they're almost always a sure-fire kill.

* **Healing** ｢体力回復｢ヒーリング｣, *hīringu*｣: A healing magic that restores the target's stamina and lost blood.
* **Holy Bell** ｢聖なる福音｢ホーリーベル｣, *hōrī beru*｣: A wave of holy power surges outwards from the user in all directions, purifying a large amount of magicules and destroying monsters while the sound of a bell sings their requiem. This magic is traditionally used to purify Undead.
* **Holy Cannon** ｢霊子聖砲｢ホーリーカノン｣, *hōrī kanon*｣: A focused beam of holy power fired outwards that rapidly purifies the magicules of a target on contact. It's the strongest single target attack spell in basic-level holy magic.
* **Holy Field** ｢聖浄化結界｢ホーリーフィールド｣, *hōrī fīrudo*｣: A barrier magic that works under the same principle as Prison Field, but ramped up the the max. It's usually maintained by several high level practitioners working in tandem. Within the radius of the barrier, purification of all magicules commences. This outright kills any weaker monsters and those that manage to survive will find themselves greatly weakened and unable to use Elemental Magic and Magic-derived Skills.
* **Prison Field** ｢四方印封魔結界｢プリズンフィールド｣, *purizun fīrudo*｣: A barrier magic that keeps monsters from escaping while filling the area with holy power. This greatly weakens most magical beings and Greater Majin will find themselves in a much tougher fight because of it.
* **Recovery** ｢傷病治癒｢リカバリー｣, *rikabarī*｣: A healing magic that closes wounds and reattaches severed limbs. However, it cannot restore the target's stamina or blood supply.
* **Turn Undead** ｢死者浄化｢ターンアンデッド｣, *tān andeddo*｣

### Miracle Level

Miracle-Level Holy Magic or **God's Miracle** ｢神の奇跡, *kami no kiseki*｣ makes use of a god's power to manipulate Spiritrons. The magic belonging to this category is immensely powerful and the offensive spells it offers are lethal regardless of if the target is a monster or not. Even an Ultimate Skill user with their immunity to lesser forms of magic will find themselves in danger against the power of miracles.

* **Disintegration** ｢霊子崩壊｢ディスインテグレーション｣, *disuintegurēshon*｣
* **High Heal** ｢上位回復｢ハイ・ヒール｣, *hai hīru*｣: A healing magic that restores a person's stamina and lost blood, but on a much greater level compared to Healing. It can also be used over a wide area for the healing of a large number of people or a large area of plantlife.
* **Holy Ark** ｢聖櫃｢せいひつ｣, *sei hitsu*｣
* **Holy Ray** ｢霊子閃光波｢ホーリーレイ｣, *hōrī rei*｣: A spell devised by Rimuru Tempest. The user fires rays of volatile, rotating spiritrons from their finger tips. The power is adjustable and its lack of holy power makes it safe to use even for monsters.
* **Regeneration** ｢部位再生｢リジェネレーション｣, *rijenerēshon*｣: A healing magic that can completely heal almost any injury and restore missing limbs and organs.
* **Resurrection** ｢死者蘇生｢リザレクション｣, *rizarekushon*｣: A healing magic that completely heals the target and can even bring them back from death if their soul is still present.
* **Overdrive** ｢霊子暴走｢オーバードライブ｣, *ōbādoraibu*｣: A Disintegration spell, but cast over a wide area, similar to Holy Bell.
* **Trinity Break** ｢聖三位霊崩陣｢トリニティブレイク｣, *toriniti bureiku*｣

## Trivia

* Since holy magic is usually associated with the Western Holy Church and monster slaying, it is widely believed in-universe that monsters are not capable of using holy magic. Therefore, most characters react in shock when they see a monster casting it.
* In Luminism being able to use "Miracles" is required to advance to the rank of Bishop.
