Kei's a teenage boy with light, evenly-cut short hair that leans pink in the official artwork, paired with green eyes. He's got this deliberate way about him—both he and Yuuichi have noted that he doesn't really do anything without a reason. Every action means something to him. That said, he's got a clear sore spot: bring up his height and he gets genuinely upset. It's pretty obvious it's something he's insecure about.
