Foul-mouthed and quick to pick a fight, but actually kind-hearted: A humanitarian who can't ignore someone in trouble even while acting tough. He has a shy side, turning bright red and getting flustered when praised or treated kindly. He constantly aims for the top to prove his worth through fighting and never gives up even in difficult situations. He has the strength to push through with his honest words without bending his principles, no matter who the opponent is.

Always maintains a gentle smile and treats those around him kindly. Calm and collected, he rarely gets emotional. He has a playful side, cracking jokes like introducing himself as "Leonardo DiCaprio" upon meeting someone. Extremely composed in battle. His fighting style is intellectual rather than reliant on brute force, reading the opponent's moves to neutralize them precisely. Shrouded in mystery. (His past episodes are key to the story, and his true inner thoughts are difficult to see.)

Timid and extremely weak at fighting, but a bright, straightforward, and serious hard worker.

An approachable leader: Lacks the intimidation typical of the strong, possessing a playful personality that allows him to interact with anyone. "Fighting is dialogue": He has the magnanimity to empathize even with the hearts of his enemies. Overwhelming charisma: As the top of Bofurin, the "Wind Breaker" protectors of the town, he enjoys immense trust from his comrades. Switching between on and off: Usually a cheerful goofball with a smile, but shows a serious expression during combat.

A taciturn and blunt "mad dog" character who swears absolute loyalty to Hajime Umemiya.

Ren Kaji appears quiet and unmotivated at first glance, but he is actually a very reliable big-brother figure with kindness and a strong sense of responsibility. While his position as the 2nd-year grade captain plays a part, it is largely due to his personal nature of looking after others.

Maintains a gentle tone and never stops smiling, but can occasionally drop harsh words toward others.

A kind personality who cares for his juniors and supports those around him as a steady, understanding ally! Because he is methodical and has a strong sense of responsibility, he suffers from stomach pains due to the stress of managing the Tamon-shu and worrying over Umemiya's eccentric behavior.
