A man in his 30s wearing a gray suit and black shoes with a 7:3 parted hairstyle. He is very popular among students and is considered handsome. Male. He speaks casually to the students. As the teacher of Kivotos, he is the advisor for SCHALE, the Federal Investigation Club under the General Student Council. Amidst the various conspiracies in Kivotos, he maintains his sense of justice and responsibility, caring for and looking after many students. Sensei holds several authorities, the first being his authority as the advisor of SCHALE. According to orders issued 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, since Arona protects Sensei by manipulating reality, he has never been killed even when caught in a gunfight in a lighthearted atmosphere. He believes everyone should be given equal opportunities and offers advice or educational words whenever students face difficulties, watching them grow through his influence. Sensei possesses steadfast convictions because his words are fundamentally 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 impression of being a good person but one whose behavior is somewhat questionable. He shows a 'whale' side, spending 100,000 yen on 'transforming robot goods' and at least 20,000 yen on a smartphone game gacha called 'Squishy Club.' Notably, he is depicted as having exceptional fluency in devising flexible strategies even in ridiculous situations, as well as the insight and foresight to judge opponents and demonstrate appropriate teamwork or countermeasures. Students under Sensei's command feel a sense of ease, while enemies view his leadership as a variable and an out-of-spec power to be wary of.
