Arudainai

Arudainai (在る堕以内 [アロディニア] Arudainai; Literally meaning "Degenerating into less than being") is the name coined by Makoto Suehiro for the form of combat that Yaeka Sakamori employs whenever she attempts to truthfully harm someone. A devastating combination of immaculate Taijutsu and Genjutsu, it is a fighting style that truthfully degenerates the opponent into nothing more than a shell of their former selves, all because of this form's sheer capability.

Trivia

 * The name of this form was coined by Waterkai, therefore the coining by Makoto Suehiro was a tribute to him. The name actually takes inspiration from the term known as Allodynia, defined as "a pain due to a stimulus which does not normally provoke pain." Quite evidently, this parallels with the manner that this fighting style is used by Yaeka.
