Rouwe is a secret boss from Galaxy Fight. Players will only encounter him if they beat the game without using continues and are given only one match against him. Regardless of whether they win or lose against him, the staff roll will appear once the round is over. Not much is known about Rouwe other than the fact that he is a hermit living in the plains. He is Bonus-kun's owner and master, and he was apparently responsible for the death of Kazuma's father.
