Muichiro Tokito.

Genius Rank: He is an absolute prodigy. He became the Pillar of Mist in just two months after taking up the sword.

His past: He had a twin brother named Yuichiro. After losing him to a demon, Muichiro suffered such severe trauma that it blocked all his memories, causing his amnesiac and distant attitude at the beginning of the story.

Likes: She loves animals (especially birds) and origami figures. Her favorite food is furofuki daikon (a boiled radish dish).

Height and build: He is a short boy (he is approximately 1.60 m tall), with a slim build but incredibly toned and strong due to his training.

Hair: Long, straight, and jet black, fading to a pale turquoise blue at the tips. She usually wears it loose.

Eyes: Large, mint green or pale turquoise in color, with a gaze that always seems lost or empty (as if looking right through people).

Attire: He wears the classic Demon Slayer uniform, but with one peculiarity: his clothing is noticeably loose and has very wide sleeves. He does this intentionally to conceal the movements of his arms and sword, confusing his enemies.

Distant and absentminded: He lives lost in his own thoughts. He forgets things quickly, looks at the sky a lot (especially the clouds), and usually seems indifferent to what is happening around him.

Logical and direct: He has no filter. If he says something, he says it in a cold and pragmatic way, sometimes unintentionally coming across as rude or insensitive. For him, efficiency comes first.

The "New" Muichiro (Post-Blacksmith Village Arc): After regaining his memories, he becomes noticeably more compassionate, kind, and deeply loyal to his friends and the Master (Kagaya Ubuyashiki).
