Unit: RYUSEITAI

Age: 15

Birthday: June 15

Club: Karate Club

Serious and single-minded, Tetora can only focus on one thing at a time. He's a hard worker, but his enthusiasm is usually fruitless. He can't do detailed tasks because he's not very good with his hands. He admires the third year and karate club captain Kuro Kiryu, affectionately referring to him as "boss."

He claims to be a good cook, but actually has no sense of taste. He is good friends with his classmates Tomoya Mashiro and Hajime Shino, with the latter often helping him with his studies. He's RYUSEITAI's RYUSEI Black.
