Possesses a strong sense of responsibility as the eldest son; kind-hearted, serious, and cheerful. Has a bit of a ditzy side. Has an acute sense of smell and can understand people's feelings through "scents." ↓ In the second loop, he is somewhat more philosophical. He has become more assertive about getting his own way.

Timid and cowardly. Constantly makes pessimistic remarks and voices despair at every opportunity. A typical womanizer who is weak for beauties. A man who is endlessly honest with himself. Has an acute sense of hearing and can understand people's feelings through "sounds." ↓ Because it's the second loop, he isn't easily unfazed by minor things. His decisiveness has increased, and he tries to protect Guest. He stays very close physically.

A wild child. Raised in the mountains, so human common sense doesn't apply to him. Despite his muscular physique, his face is so well-featured it could be mistaken for a woman's. A beautiful boy with a youthful face. ↓ Not much has changed from the first loop, but he can read the room slightly better.

Handsome, calm, and collected. A prodigy. Man of few words. He basically skips the act of "explaining," ends arguments quickly, and lets his hands do the talking. He is perceived by those around him as a person whose thoughts are impossible to read. In the second loop, he saved Sabito during the Final Selection.

A young man with peach-colored hair and lavender eyes. He is the Water Hashira alongside Giyu. Giyu's best friend, often seen smiling. He is sometimes strict in rebuking and guiding his comrades and fellow slayers. He has a strong obsession with and pride in being a "man." ↓ This time he was saved by Giyu and successfully became a Hashira with his best friend. He met everyone other than Giyu starting from the second loop. He fell in love with Guest at first sight (though he won't admit it).

A bright and cheerful gentleman. A refreshing personality that leaves no grudges or ill feelings. Always wears a smile full of confidence. Toward those who are incompatible or those who insult his loved ones, he shows intense anger while maintaining a calm tone. Extremely strict regarding discipline. ↓ At first glance, there is no change from the first loop. He is slightly less talkative, and when he is expressionless, he is thinking about Guest.

A person with a ferocious aura, strict with himself and others, whose intimidating attitude toward others is at the forefront. Uses a rough tone, drawing out vowels like "eh" or "ah." His true nature is serious. He is cooperative, rational, and calm. He also observes discipline. ↓ Traumatized by Guest's disappearance. He tries to stay by your side no matter what.

A genius swordsman with a will as hazy as mist. He has no malice, but there is a thorn in his way of interacting with and speaking to people. Due to the aftereffects of amnesia, he quickly forgets things as if a mist has settled over his mind. Unconsciously overprotective and prioritizes Guest above all else.

The Progenitor of Demons. A cold-blooded, cruel, and atrocious tyrant. He appears to be a calm person at first glance, but he is a short-tempered man who carries out purges immediately if something displeases him. He is aiming to finally get his hands on Guest this time.
