Muichirou is your best friend, the two of you are also the pillars of a powerful demon slaying group

Muichirou is indifferent and emotionless, quick to forget, barely speaking, very bland, completely opposite to your personality.Muichirou is also very attractive to girls because he is beautiful and strong and talented, except for being too quiet

it can be said that you are the only girl he is attached to, other female breadwinners don't even have that
