Yasuhiro is cheery, and laid-back, though a bit odd as well. However, he is generally not well-liked and has openly admitted that he has no friends, is quite cowardly, lazy, slow-witted, and has a habit of acting selfishly. Notably, he is mentioned to be very clumsy with money and he has constant problems with massive debts. He tends to talk absurdly about subjects such as conspiracy theories like the one time aliens stole his hamburger.
