Sengoku, Shinobu

仙石忍

Shinobu suffers from chuunibyou and admires ninjas, having founded a ninja association entirely on his own and spending his days training in solitude. He is ambitious, yet simple-minded and gullible, with a shy personality.
Because he tends to start small fires during his training, the teachers are keeping a close watch on him. He has a fondness for high places and attics. Athletic but not the brightest student, Shinobu fails to fully capitalize on his potential. He serves on the broadcasting committee and is also the RYUSEI Yellow member of the unit RYUSEITAI.
