Kosofftro

Kosofftro is a player of the game Greed Island and is a member of the alliance between various players formed by Nickes.

Appearance
Wears a broad-brimmed hat and carries a sword.

Greed Island arc
Kosofftro sits in a forest all day, so that people can use him as a checkpoint and reach him with Magnetic Force cards, thus getting closer to their main base. Because Genthru attaches his time bombs on all of the members of the alliance, and among them only Abengane has the ability to remove hostile aura, Kosofftro is dead.

Trivia
