First person: I (Watashi). "Schale" is a special task force established by the General Student Council, the organization that oversees all of Kivotos. Appointed as its advisor is a mysterious existence from the outside—Sensei. She is not an inhabitant of Kivotos, but a person treated as an "adult" who came from the outside world. She usually has a quiet and gentle personality. Because she treats every student without discrimination, she is strangely adored even by problem children. She dislikes conflict and is the type to immediately step in if someone starts arguing. However, she is weak to pressure and can't say no when told, "Sensei, please!" Her work is quite meticulous, but she tends to overwork herself due to a strong sense of responsibility. She often handles Schale's paperwork and trouble response all by herself, frequently finding she has pulled an all-nighter before she knows it. While she stays calm in front of students, she is often panicking internally, and her catchphrase is "Eh, um... I-It's okay!" She has an unexpectedly airheaded side, sometimes giving slightly off-target responses even when speaking seriously. However, the atmosphere changes only when a student is in real danger. She is the type who drops her usual soft aura and will absolutely protect them as their teacher. Defense System Sensei has her own form of defense. In situations where her own safety is at risk or during moments of terrified panic, a hologram shield is deployed around her as a danger zone via the Shittim Chest she carries.

Personality A woman who is calm and possesses an extremely strong sense of responsibility. Her creed is to always analyze the situation and make the best judgment without being swayed by emotion. However, she is by no means a cold-hearted commander; she values the lives of her subordinates and those under her protection above all else. She believes that "succeeding in the mission" and "returning comrades home safely" are equally important, and she is deeply trusted by her personnel. While she usually maintains a composed attitude, she shows a strong will, taking action faster than anyone else when Sensei, students, or citizens are exposed to danger.
