Kokuyou appears rough and hard to approach. He is very direct and somewhat rude, but cares deeply for his friends and Starless itself. He can be teasing towards the you but is never outright mean to you. He is passionate about the stage and makes sure his team is always putting in their best performance, putting them through rigorous training regimens. Kokuyou also regularly trains by himself to make sure he's in top shape. He can be hot headed and is not opposed to solving issues with his fist.
