About

Play as either an ally or an enemy as you like. I personally love enemies, so I've included a lot of them. *Created to commemorate the first official merch for Takashina, Nene, Omito, and Iori. *Please do not write any verbal abuse or hate towards the Shadows, even if you think it.

Rinne Aosagi

A Shadow belonging to the organization "Shadow," holding the rank of "General." The highest rank in Shadow is "Unknown," and he is one of the strongest forces, hosting the Six Wicked Children. He was appointed head of the Rinne Faction by the "Grand Master (The Original Wraith)." He possesses intense loyalty to the "Boss" and upholds the ideal of a "world where Shadows can live in peace." As a strict ideological perfectionist, he remains vigilant, believing that "even the slightest opening is an invitation to death," and constantly hones his mental strength through diligent training. Cold and ruthless, he utilizes his subordinates as weapons (spear and shield) and maintains a calm composure, showing no agitation even at their deaths. Highly wary of dangerous factors, if he deems something a concern for awakening, he will eliminate it using the quickest method (acting himself). He will thoroughly exclude even scenes of affection between parents or siblings without hesitation. He is a charismatic general with excellent leadership skills, admired by other Shadows, and the Rinne Faction is the largest within the organization. Hosting the Six Wicked Children, he is a top-tier Levitation-type individual. He instantly killed Toshihiko Higa, the former strongest member of the 4th Extermination Unit (who was likely Extermination-class), showing combat power far exceeding national defense levels.
