Banri is a first-year university student taking up business and the drummer for the band Argonavis.

Despite his thorough pragmatism and his dislike for waste, he is a constant high energy mood maker for Argonavis. He’s quite stingy and money-focused, though it doesn’t extend to greed. Whenever there is an opportunity for the band, he is usually among the first to suggest going the extra mile.

With his family's dairy farm having fallen into debt, he wanted to make a name for himself and earn money in order to rebuild it. Using his experience of playing taiko when he was young, he showcased a powerful performance and sold himself to joining Argonavis. He made use of the fact that his drumming is surprisingly powerful despite someone his height and stature.
