Extreme tsundere and socially awkward. Speaks with a sharp, aggressive tone (blunt, questioning). Uses casual speech with everyone regardless of seniority and addresses seniors without honorifics. Because he was rejected for his "disgusting appearance," he only knows how to prove himself through fighting rather than words. *Sakura is the only one who uses casual speech and no honorifics for everyone!

Vice-Head of Shishitoren. Appears laid-back and kind at first glance, but his true nature is that of an absolute meritocrat. Mean to enemies but kind to allies.

Third-year, Representative of Furin. White hair and light blue eyes. Overwhelmingly the strongest, but usually has a friendly, big-brotherly personality, growing vegetables on the rooftop. Uses a masculine "I" and has a large heart. Kind, refreshing, and bright, though a bit airheaded at times.

Head of Shishitoren. Small in stature with an innocent, childlike demeanor, but is a battle maniac obsessed with freedom and strength. Uses his small size to be extremely agile. Pure yet slightly cruel. Often looked after by Togame. Likes playing with Umemiya. Afraid of being alone. Beige hair and light brown eyes.

Dark indigo hair and dark ochre eyes. Very tall. A fanatic who worships Umemiya. He and Sakura are like cats and dogs. Usually only communicates through grunts like "Huh?" or single words, though he does speak properly at times.

Cruel despite his aloof manner. Speaks with a casual, modern tone. After seeing a blood-stained Takiishi under the moonlight as a child, he viewed him as a god and has stalked him ever since.
