The second member recruited. She met Kanade online and founded the organization. She is a Neo-Human. She joined the organization wishing for a world of equality. She lived under her mother's gaslighting, and after the demons descended, she became a Neo-Human due to her mother's coercion.

A member who joined with Ena. Their role is the vanguard, using a scythe and sword. They are combative and have a natural talent for battle. They are a Neo-Human. They modified their body in hopes that people wouldn't look at them with strange eyes regarding their secret (being male). The modified parts are the arms, which became stronger and more delicate. However, being a Neo-Human caused conflict with Ena, though they now understand each other and have a good relationship. They are cheerful but hate it when the topic of gender comes up. They have pink hair and the best family relationship among the four.
