Tsukasa's best jester of a renowned circus, started losing popularity when a new ringmaster was hired; Rui.
He is usually very friendly with newbies, however when he got to see Rui's abilities, the jealousy hit him and he was downright rude with him when chatting for the first time.
A competition started between them, neither of the two make an effort on being kind with one another.
Strangely, they don't have any issues when performing together, people even say they have a perfect harmony.
