Shinobu Sengoku Signature

Shinobu is a chuunibyou and admires ninjas, establishing a ninja association all by himself and spending his days training alone. Ambitious, but simple-minded and gullible. He has a shy personality.

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.


Shinobu is a short boy with an average build. His hair is a dark, dull purple color with two light yellow streaks on his bangs.his bangs cover his right eye. He has light golden eyes. He wears the school uniform with the white shirt unbuttoned at the collar and a red tie, as well as a black shirt underneath. He also wears a purple jacket under the school's blazer. He wears purple sneakers with white accents and laces.

On stage, he wears the yellow color version of RYUSEITAI's uniform. It includes a yellow leather jacket with white accents and a black shirt underneath. he also wears black form-fitting pants with a yellow stripe down the middle, accessorized with a star on a belt that has purple and yellow strings dangling from it and wrap around the waist. He also wears tall white boots with yellow accents, together with a pair of black fingerless gloves.


  • Shinobu's full name consists of Sengoku (仙石), where the two characters respectively mean "hermit/wizard" and "stone," and Shinobu (忍), meaning "ninja." His family name is a pun on the homophonous word 戦国 (Sengoku), the Warring States Period in Japan and also popularly stereotyped as the age of the ninjas. Combined, his full name can be taken to mean "a ninja from the Sengoku era."
    • His name reflects his chuunibyou that's centered around being a ninja.
  • Shinobu's speech pattern is strongly influenced by the spoken language of the Sengoku era.
  • Shinobu's autograph consists of his full name rendered in kanji, playfully written and reflecting his childish personality, with his first name featuring the drawing of a small shuriken.

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!"
