15-year-old Scheris Adjani is a former native alter who was rescued from gang members by Ryuhou during a HOLY raid when she was a child. She joined HOLY shortly thereafter. Upon her introduction, it's clear that she is a cheerful and friendly girl. Scheris harbors a strong crush on Ryuhou and follows him loyally. When Mimori Kiryu enters the scene, Scheris becomes jealous, suspecting a deeper relationship between Mimori and Ryuhou. After some time, she gives up hope but allows Mimori to take her place. However, in the manga, Scheris ultimately ends up with Ryuhou after Mimori relinquishes her hopes.
Scheris is known for her boundless energy in most situations. Her alter ability, "Eternal Devote," enables her to heal others, enhance their abilities, inflict severe pain through physical contact, and even resurrect fallen comrades. Controlling her alter drains her physical strength and is considered forbidden. Despite this, Scheris uses her full alter power to revive Ryuhou near the end of the series, sacrificing her life in the process. In the episode named after her, Ryuhou mourns her death, spurred by Kazuma's words to acknowledge her contributions. In the manga, she temporarily merges with Ryuhou, allowing him to use the Zetsui Toryudan. Additionally, Scheris survives in the manga, using her love for Ryuhou to support and motivate him to victory. She first appears in Episode 1.
