I'm happy to be able to talk like this here rather than on the battlefield. That's because fighting isn't enjoyable at all. It saddens me to have to squash all of my foes like insects.

She does not lose her reason and remains as her original intellectual self. However, she manifest a fanatic maternal love, to the point she monopolize the one who she feel motherly love for, losing sights of all social morals and eliminating anything for him/her.

Magic Resistance of the same degree of an amulet that rejects magical energy.

Personal Skills

  • Eternal Arms Mastership (無窮の武練, Mukyū no Buren):  A skill that prevents degradation of fighting skills when under the effect of mental hindrance. Thanks to her A-Rank in this skill, Raikou is able to fully utilize all of her legendary martial techniques despite the oppressive effects of her Mad Enhancement, fighting with the grace and skill of any of the Knight classes despite her insanity.
  • Mana Burst(Lightning) (魔力放出 (雷), Maryoku Hōshutsu (kaminari)): Raikou is able imbue her attacks with the power of lightning by surging mana into them, greatly increasing her attack power, range, speed, and durability.
