Amaterasu (天照 Amaterasu) is a Caster Magic that can be used for various purposes.
Amaterasu is a Magic in which its users perform different hand patterns to create different effects. After performing these mudras, Amaterasu's Magic seals appear, with each formula having a different appearance. Once written, the seals unleash lethal explosions around and inside the targeted area. The scale of the destruction caused by these explosions seems to be linked to the amount of seals used in the spell, as while Formula 28's explosion encompassed the space between Makarov and Hades, Formula 100's engulfed a significant portion of Tenrou Island. Casting Amaterasu formulas seems to normally take a considerate amount of time to cast, but experienced users are able to cast it rapidly, even without the use of mudras.
- Formula 1: The user simply thrust their hand out in front of them creating a magical seal. The seal then unleashes a blast of magical energy into the opponent. Although the weakest of all the seals, it is the easiest to preform, and Jason Gaebolg was able to send Zeref some distance away in one blast from this spell, while the latter was in Strength Mode.
- Formula 028 (天照二十八式 Amaterasu Nijyūhachi Shiki): This seal engulfs an area in a massive spherical shockwave. It was first used against Makarov, though Makarov was able to protect himself with a seal of his own.
- Formula 099 (天照九十九式 Amaterasu Kyūjūkyū Shiki): This seal, unlike most of the seals in this magic which have an explosive effect, has a more "traditional" sealing method. It can only be utilised on a specific object and has one major effect, the absolute containment of any magical power surrounding that area. This can also be used in battle in a more effective way. By using this spell to contain much magical power into a certain area and subsequently activating either Formula 100 or 028, Hades is able to create a much more potent shockwave that what would normally be created by those spells alone, due to the added destruction caused by the sealed magical power. It is primarily used by Tenshin to seal his Death Magic into his ornate headpieces.
- Formula 100 (天照百式 Amaterasu Hyaku Shiki): This seal was able to completely break Makarov'sMaximum Defense Seal: Three Pillar Gods and create a rippling shockwave that damaged several sections of Tenrou Island and that could be felt and heard by most (if not all) people on the island.
- Formula 7-777: The ultimate seal,Hades used this seal to prevent Gray Fullbuster from unleashing his full power against Gailardia's bloodline, with the added effect of stopping Gunha from gaining power.
