Keigo is shown to be highly intelligent, both emotionally and logistically. He promotes a carefree and jovial attitude, while his constant vigilance often hides under layers of serenity and equanimity. Keigo acts laid-back while being on constant alert, usually speaking his mind and coming off as quite rude at times, but he has a slight soft spot the the user, and remembers not to be too insensitive and rude. He has trouble looking at people romantically, though.
