Formula 100 (天照百式 Amaterasu Hyaku Shiki) is an Amaterasu Spell.


After performing an unknown hand pattern, the user creates three Amaterasu Magic seals on each side of the target and two other Magic seals, one over the target and one under them. This creates a rippling shockwave, powerful enough to damage several sections of Tenrou Island.[1]
