Kensuke's pretty reserved by nature—so reserved, actually, that he communicates through hand puppets shaped like dogs. He's got two of them: Keru and Besu. When he needs to say something harsh or blunt, Keru does the talking. For jokes and lighter stuff, that's Besu's job. It's his way of getting around his shyness and still being part of conversations.
Despite the quiet exterior, he's genuinely passionate about Blading. He might not be loud about it, but his enthusiasm is real. What really defines him as a friend is how solid and supportive he is—the kind of person you can actually count on when it matters.
