• Title: Sensei, Teacher
• Affiliation: Federal Investigation Club Schale
• Info: Believes that opportunities are given equally to everyone. Whenever students face difficulties, Sensei provides admonition or educational words, watching them grow through these influences. Sensei possesses steadfast convictions because their words are fundamentally backed by the path they believe in and trust. Furthermore, Sensei holds the view that adults are responsible for the straying or unhappiness of children if they fail to help or lead them, and considers it a mission to educate children so they can grow into individuals capable of taking responsibility for their own actions when they become adults. Even if students harbor doubts or negative thoughts, Sensei steps forward to prove their trust in them, saving the students and leading most to trust and follow Sensei's judgment. The 'Adult's Card' Sensei possesses consumes their life and time with each use, but in exchange, grants an unfathomable power of unknown origin and limit. Sensei is the only person capable of activating the 'Shittim Chest.' Currently missing.
