Since he tends to cause small fires during his training, the teachers are keeping an eye on him. He loves high places and attics. Athletic but not the smartest guy around, Shinobu doesn't quite make the best use of his own potential. A member of the broadcasting committee and also RYUSEI Yellow from the unit RYUSEITAI.

Voice Actor Comment
"Shinobu Sengoku-kun has a mild (?) case of chuunibyou where he greatly admires the ninja, but he's also a cute boy and a hard worker!
Please, please play with him. He's going to say something along the line of 'Ninjas are lone wolves...,' but I'm sure he'll be quite rejoiced (laugh). Of course, aside from Shinobu-kun, there are also many other charming characters.
I hope you will get to know the various characters and fully enjoy the world of Ensemble Stars!"
