Muichiro Tokito

Muichiro Tokito (時透 無一郎 Tokitō Muichirō?) was a Demon Slayer and the Mist Pillar of the Demon Slaying Corps. Muichiro was a short young man of light complexion with long, straight hair of a dark black color that faded to pale turquoise the closer to his waist it extended. He wore it 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 possessed large, empty-looking, mint-green eyes, a trait, like his hair, that he shares with his twin brother, Yuichiro Tokito. Muichiro wore a dark, slightly turquoise-tinted of the Demon Slayer uniform, just with longer, looser sleeves that are more reminiscent of those of a kimono than of the standard cuffed uniform, and no bands of cloth around his calves, which gives his uniform an overall loose and sizeable appearance. Muichiro was an air-headed individual who seemed to constantly wander off in thought and never focus on one thing. Impassive and, at times, obtuse, he tended to think only for himself and operated on logic alone, never letting emotion guide him. However, he has been shown to get serious when it was required and was devoted to his position as the Demon Slaying Corps' Mist Pillar. When he was 10, before the death of his twin brother, however, Muichiro's personality was that of a much more caring individual. Having originally taken after his father, he has been shown to display much more kindness and understanding than fits his current demeanor, believing that he should aim to do good for others if he wanted good to be done for him. However, despite this, he always held an omnipresent rage deeply suppressed inside of him that inevitably drove his later training. After his memories returned, he started expressing more emotions and became more confident in himself. He also learned other expressions such as displaying sarcasm and smugness towards the fifth upper moon, Gyokko. Muichiro and his older twin brother, Yuichiro, were born to a woodcutter and his wife.

When they were 10, their mother caught a cold which developed into bronchitis and killed her and their father, away at the time, went to fetch medicinal herbs for her during a storm and ended up falling off a cliff to his death. The two siblings survived together, while Muichiro took after the emotive and kind nature of their father, Yuichiro instead held a cold and impassive outlook on life. In the following spring, Oyakata's wife, Amane arrived to recruit them for the Demon Slaying Corps. Muichiro's excitement was opposed by Yuichiro's unwelcoming and rejecting reception. In an outburst, Yuichiro revealed that he blamed the death of their parents on their hardworking and selfless nature and adopted a cold outlook, hoping to keep himself and his brother alive. While Amane continued to visit the twins, Yuichiro chased her away each time. In the following summer, a Demon arrived at their cabin during the night and attacked, and as a result Yuichiro lost his left arm while trying to protect Muichiro. As the Demon badgered them for their worthlessness, Muichiro lost himself in a rage and destroyed the Demon with all the tools at their disposal and wooden logs. By sunrise, the Demon withered into ash and Muichiro dragged himself back to the house. There, he found Yuichiro near death praying to the heavens that his brother might survive. He laid there grasping his brother's hand as he died. Amane and her daughters later arrived to heal him. Afterwards, Muichiro would lose his memories and leave his old life behind to serve the Demon Slaying Corps, and, due to his strength, he quickly rose to the rank of a Pillar. With his memories gone, he began taking after Yuichiro's personality. He also met Kyojuro Rengoku during this period in the Demon Slaying Corps, who told him to do the best he could as a fellow Pillar. The first kanji of Muichiro's first name, "nothingness" (無 mu?), is noted to also be used to write the word "infinity" (無限 mugen?).
