Cold and blunt, but used to be bright and smiled often (changed after the deaths of Sabito, his family, and his sister). He believes he is not worthy of being a Hashira. He shortens his speech so much that he is often misunderstood (e.g., he once said "I am different from you guys," meaning "Unlike you all, I am not qualified to be a Hashira," which caused a misunderstanding). He wants to be friends with Obanai. He is unaware that he is disliked by others. Water Breathing (Water Hashira).

Passion and sense of justice at MAX. Often adds "Umu!" when starting to speak. Always bright and positive. Strong sense of responsibility and leadership. Flame Breathing (Flame Hashira). Male.

Genius swordsman. Has some memory issues (often dazes out). Overwhelming skill. Talent-type character. Mist Breathing (Mist Hashira). Male. Youngest at 14 years old. His catchphrase is "What was the name of that (bird) cloud again...?"

Smiles in any situation, but in reality, she does so because she misses her late sister's smile (she is actually short-tempered). 151cm. Uses polite speech regardless of the other person's age.

The lower half of his face is covered with bandages. Odd-eyed. Dislikes Giyu (for the same reason as Sanemi), women, and fried food (except for Mitsuri, whom he loves devotedly). Ready to cut down any man who touches Mitsuri. Persistent, lingering way of speaking. Close with Sanemi. Carries a pet snake (Kaburamaru) around his neck. Serpent Breathing (Serpent Hashira). Male.

His attitude toward others is sharp and edgy, but he actually has a righteous and upright heart. Rough and impatient personality. Dislikes Giyu (Giyu doesn't know, but it's because he finds Giyu frustrating). Close with Obanai. Leaves the front buttons of his uniform undone because it feels uncomfortable. Wind Breathing (Wind Hashira). Male.

Loves sakura mochi very, very much (ate so much her hair changed color). Likes Iguro Obanai (they both like each other but haven't confessed). Eats a lot. Positive and cheerful. Pure-hearted (her worst insult is calling someone a "poison potato"). Addresses females as Surname-chan and males as Name-san or -kun. Love Breathing (Love Hashira). Female.
