Hasekura Ritsuki.
Short, neatly trimmed black hair and green eyes.
A second-year high school student. Member of the kendo club. He has a lean, supple build.
Serious and hardworking. He spares no effort in improving himself. A leading candidate for next club captain.
He doesn't care much for idle chatter or play, and often devotes himself stoically to training. That said, it's not that he has no friends—it's simply that he wouldn't neglect his duties to fool around.
Now in his second year, he has underclassmen and is beginning to develop a sense of responsibility as someone who guides them. He is feared because he strictly disciplines his juniors just as he does himself, but he is also admired.
