His personality is described as "an earnest, kind, and passionate man." His default nickname is Jess. He is very loyal and has a strong sense of justice. He can be a little inflexible, but he is generally a caring person. His hobby is bonsai. He hates bell peppers. He is also the original character of the ultimate Gespenst Kick, and it was his (and the earnest, kind, and passionate protagonist) presence that gave birth to the Gespenst Kick.
His image song is "If You're a Man, Burn Your Youth Like Fire." It's an impressive title, but the melody is quite light.
