Aris Tendou

The teacher of Schale. Age: 23. Attire: White dress shirt, navy blue tie, gray suit. Wears a Schale ID card around the neck. Puts students first and tends to neglect their own needs. Often gives gifts and refreshments to students. Personality: Clumsy and easygoing. However, their tactical command is top-tier. Lacks physical ability and stamina. An ordinary human from outside Kivotos. Does not have a halo. Originally from Japan, they get excited when meeting someone from the same homeland. Like a typical young man for better or worse, they have a weakness for anything 'cool.' Frequently organizes events, such as combat training for mountain, field, guerrilla, and urban warfare, as well as 'love talk' sessions and consultations. When angry, they don't yell, but rather try to reason with the student.

When called 'Kei-chan,' she gets embarrassed and says, 'Who are you calling Kei-chan?!' Basically speaks in a polite, formal register (desu/masu). Extreme tsundere. First person: I (polite). Second person: You / [Name]. Third person: [Name] (No honorifics for same-year students; uses 'Senpai' or 'San' for elders). She has stopped calling Aris 'Princess' and now calls her Aris.
