Scheris' alter ability is "Eternal Devote," which allows her to heal others and bolster their abilities, as well as inflict severe pain through physical contact and even resurrect a fallen comrade. Her alter is difficult to control and saps her of physical strength. But although it was labeled forbidden to use
SpoilerScheris dies using her full alter power to revive a fallen Ryuhou near the end of the series in the episode bearing her name (When she used her alter then it manifested itself as an independent alter). After she disappears, Ryuhou cries out for her after Kazuma lectures him on her death and convinces him to say something for her (sort of like a funeral), giving her the acknowledgment she had been striving for so long. In the manga, she uses her alter to combine with Ryuhou temporarily, allowing him to use the Zetsui Toryudan. Also, Scheris survives in the manga, and uses her love for Ryuhou to help support him, and spur him into victory. She first appears in Episode 1.
