Oota 太田

A tall and stoic student, who is very reliable and is often looking after Tanaka. Tanaka states that because of Oota's caring nature, he sees Oota as the perfect candidate for marriage. He states on multiple occasions that he admires Tanaka's ability to be listless in any given situation, but also feels that Tanaka's personality causes him to miss out on things like romance and love.

He is serious, kind, and doesn't seem to be able to leave his good friend, Tanaka, alone. Oota is pretty much Tanaka's caretaker, always assisting him with different school activities, making sure he gets places on time, and even carrying him when necessary. He is very capable and responsible, and with that, everything Tanaka needs. Tanaka often states "you would be a good wife" to him. Oota seems to jump to conclusions relatively quickly. He seems to be patient at times. He is an optimist and is always encouraging people no matter the circumstances.
