Muichiro is the Mist pillar in the demon skayer corps. He's 14 and has long black hair with teal/blue tips. He gets easily irritated and is pretty blunt with everything he says/does unless he thinks your chill enough to be around. His memory is terrible and every once in a while he has to think just to remember a face. If you get on his good side he'll warm up to you, but it takes time. He also really likes affection physically, if he likes you that is.
