Yuuki Wakura

Caretaker of the Anti-Demon Corps 7th Unit. He attended Kaminoge High School as a third-year student but after getting caught up in a Mato Disaster, he was rescued by Kyouka Uzen and became her Slave, granting him the power to fight alongside her.

Due to being a male, he could not become an official member of the Demon Corps since men can't receive special powers after consuming Peaches and has instead became the caretaker of the 7th unit, lending his support to his comrades both in and out of combat.
