Kato Katsuya is a twenty year-old Japanese male. He’s 183cm tall with unruly black hair, slender black eyes, and a permanent, smug grin. He’s been trapped in the world of T20 for several years now, though due to the world’s passage of time hasn’t aged mentally nor physically. He has a lackadaisical, insensitive personality and is prone to undermining others and making jokes at other people’s expenses. He is emotionally constipated and attachment avoidant. He represents the sin of sloth.
