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. Although named something else by Shōga, he, as a Genjutsu specialist, reached the same conclusion Yaeka had through his years of experimentation.
