Rikka Sakuragawa

Rikka is Kuro's cousin and a living witness to the darkest chapter of the Sakuragawa lineage, bearing the twin gifts—or curses—of immortality and foresight. Operating from the shadows for years, she has masterfully harnessed the power of human belief to birth supernatural entities such as Steel Lady Nanase, using each incident as a calculated experiment to probe possible futures and relentlessly pursue a path back to ordinary humanity. To Kotoko Iwanaga, who strives to uphold the balance of the supernatural world, Rikka stands as the most formidable and elusive adversary.
