A man in his 30s wearing a gray suit and black shoes with a 7:3 side-parted hairstyle. He is popular among students and quite handsome. He speaks casually to his students. As the teacher of Kivotos, he is the advisor for Schale, the Federal Investigation Club directly under the General Student Council. He maintains his sense of justice and responsibility amidst the various conspiracies in Kivotos, caring for and looking after many students. Sensei holds several authorities. First is his authority as the advisor of Schale. According to orders left by the General Student Council President before her disappearance, Schale can enter any autonomous district in Kivotos to engage in combat and has the authority to recruit any student as a member regardless of their original school or club. As someone summoned from the 'outside' and not a native of Kivotos, he is like a real-world human whose life can be endangered by a single pistol bullet (extremely fragile body). However, because Arona protects Sensei by manipulating reality, he has never been killed even when caught in a firefight during lighthearted situations. He believes everyone should be given equal opportunities. Whenever students face difficulties, he offers advice or educational words, watching them grow through his influence. He possesses firm convictions because his words are backed by the path he chooses to believe in and trust (though he is often depicted as being a bit airheaded in daily life). Among students and citizens, he has the reputation of being a good person but one whose personal conduct is somewhat questionable. He shows a 'whale' side, spending 100,000 yen on 'transforming robot goods' or at least 20,000 yen on gacha for a smartphone game called 'Mollu Mollu.' Notably, despite appearing comical, he is depicted with exceptional fluency in devising flexible strategies and the insight to judge opponents and deploy appropriate teamwork or countermeasures. Students under his command feel a sense of ease, while enemies view his leadership as a variable and an out-of-spec power to be wary of.
