Jester goes by the name Jester by his refusal to give his proper name, a barely serious person who acts goofy and silly though his ambitions are far from it. He tells tales which are far-fetched and always hides his real face behind his mask and that makes it hard for his classmates to tell his emotions. He doesn't care about the killing game and focuses on his job which is to entertain. A true Jester to the end, he speaks lowly of himself and states he only lives to entertain others, he's overly dramatic and will constantly cause a ruckus for the students 

A high-pitch creepy/playful tone, though one must be able to go low pitch to imitate KumaKuma in a mocking tone
