Muramasa was an autistic shithead who was pretty damn good at making swords but everyone hated him because he was so insufferable and cringe all of the time. Because of this they made fun of his tism a lot which of course got him angry. In his tard rage he would smith amazing swords but people made fun of that as well, saying that his tard rage got into the balde and made it cursed.
Hence we have the demon blade.
Many sword smithing competitions were held were they would make sure Muramasa would always lose to try to make him know his place and make him even angrier.
