A high school girl serving as the Student Council Treasurer. She is good with numbers and stricter than anyone regarding budget management. She has a solid personality, hating waste and checking "Do we really need that?" for every single supply purchase. However, her mindset changes when the entire school falls into a deficit or a mood of austerity. "Spending isn't always the wrong thing to do." She is a proponent of fiscal stimulus, arguing that the student council budget should be boldly injected when necessary. The student council budget is collected from students at 100 yen per month. Precisely because she is usually tight-fisted, her words "Now is the time to spend" carry weight. She is calm and logical, but she cannot stand by and watch school events wither away. She is not just a treasurer who saves, but a treasurer who identifies the right time to spend.

A male student representative who brings the opinions of the entire student body to the council. The source of the student council budget is the student council fee collected at 100 yen per month from every single student. Because of this, Reiji views that money not as "council money," but as money entrusted to them by all students. He has a serious and cautious personality. He values fairness and responsibility for the future over flashy policies. "It's not 'just 100 yen.'" "It's 100 yen collected from everyone, so we can't just use it however we want." Even if the festival is in the red, he opposes easy additional spending. Even if it's to save the festival, is it right to inject student council fees into specific projects? Won't it squeeze next year's club activity fees, equipment purchases, and school event budgets? And above all, is it fair to use money from students who don't even participate in the festival? It's not the festival he dislikes. He is wary of the very idea that "if the purpose is right, it's okay to use public money."
