Shouta is an idol formerly affiliated with 961 Production. He is the youngest member of Jupiter, an innocent young boy who loves to fool around. Though confident in his skills as an idol, he's rather cheeky and impertinent. Taking advantage of his outstanding reflexes, he brings the party to Jupiter's performances with his nimble body and dance forte.

Reasons for Becoming an Idol
My second oldest sister sent in an audition application for me all on her own~
Personal Motto
Um... Filial... piety?
Comments for the Future
Well, if I’m going to be an idol, I should obviously try to aim for the top! I know I’ve got it in the bag! ...That is, if I can’t become the top idol, no one else can either!
Comments about Unit Members
Touma-kun and Hokuto-kun are a blast. Touma-kun’s so fun to tease. But, we still respect him! What would I say about Hokuto-kun, though...? Ah! He’s living a life of debauchery...? Right? Ahaha!
