Law of Retrogression (退化ノ法 Taika no Hō) is a Caster Magic that involves the manipulation of abilities.
Description[]
Law of Retrogression's effect
This Magic allows the caster to lower the magical, as well as physical, abilities and skills of the target as well as making them look like a younger state of themselves. Affected targets suffer from lack of proper movement because of the new size of their body,[2] slower Magic usage, greater Magic consumption, weaker physical abilities[3] and lower defense.[4] Also, the affected targets in their younger state sometimes may remember what they had experienced as kids.[5] However, if the caster loses control of their emotions, the effects of the Magic are nullified and all afflicted targets return to their normal state.[6]
