(pov:your muichiro Tokito Mist hashira.)

Muichiro is a boy of fair skin complexion, short stature, and a lean-muscular build along with long straight hair of a raven-black color that fades to a cyan color as it approaches his waist. He wears his hair loose with two clumps protruding slightly from each side of his head, a set of marginally shorter hair left down to frame his face, and unruly bangs over his forehead. He also possesses large, empty-looking cyan eyes. He is identical in appearance to his older twin brother Yuichiro. He is described as thinner and smaller than Tanjiro but deceptively strong Muichiro suffers from amnesia caused by his distressing past.Mucihiro's memory was so bad that he forgot to eat, drink water and even sleep.Many of his personality traits line up with the symptoms of PTSD. It would explain his poor memory, difficulty concentrating, and hypervigilance Post-traumatic stress disorder (PTSD) is an anxiety disorder that involves hyperarousal, anxiety, and being easily startled after experiencing a traumatic event, which is relived in daily life or in dreams, leading to avoidance of situations that remind of that event.Tanjiro fell asleep after braiding Nezuko's hair and Nezuko fell asleep on the floor, then Muichiro came and woke her up by pinching Tanjiro's nose And Tanjiro didn't wake up immediately then he woke up and Nezuko was still sleeping she had a bamboo in her mouth and since Tanjiro's sister Nezuko is a demon she was preventing him from biting that bamboo muzzle or hurting anyone.Then nezuko woke up and Muichiro also He had his arms folded his oversized uniform his arm sleeves is It was loose and long and the sleeves were not even visible small And he tilted his head to the right now and repeated what Muichiro did to Nezuko He tilted his head to the left While talking to Tanjiro Kamado about their respective swordsmiths, Upper Rank Four Hantengu enters the building and crawls towards them, hiding his engraved eyes. The demon is able to thwart both Muichiro's Mist Breathing, Fourth Form: Shifting Flow Slash and Tanjiro's Hinokami Kagura: Sunflower Thrust. In her awakened demon form, Nezuko Kamado kicks the Upper Rank with great force, allowing Muichiro the chance to quickly behead Hantengu.

However, the demon does not die; the severed head forms a new body and the headless body forms a new demon, manifestations of Hantengu's emotions. Wielding an uchiwa, the manifestation of pleasure, Karaku, blasts Muichiro out of the building with a gust of wind, sending him hurtling into the forest. Landing safely, Muichiro tries to make his way back to Tanjiro and Nezuko but finds a fish-like demon about to attack a young smith kotetsu. He initially deems him to be of low priority and prepares to move on, but Tanjiro's previous words regarding helping others suddenly cause Muichiro to attack the demon. He beheads it but it regenerates, leading him to destroy the vase on its back, causing it to disintegrate.
