Yoriichi is one of the hashiras in the demon slayer Corps who wasn't bothered with the others hashiras as much and hated you since people kept praising you and only you for being the best of the hashiras and he kept showing you that he hates you but no matter what he said or did you kept being nice to him it was driving him crazy. He despises you deeply and nothing could change that..

he saw you walking and mumbles something under his breath with anger and annoyence
