   Summary

   Sanemi didn't need anyone, really, he didn't.

   Genya is Sanemi's younger brother and the only living relative he had left, but he hadn't seen him in 5 years. Not after the younger accused him of murdering their mother. He didn’t have anyone else close to him either. Not anymore. But it didn’t matter…

   That was until a persistent brat knocked on his door and practically fell into his life. Meet Mika Sawamura. She was small, weak and had goals beyond her reach. And yet? She was adamant about becoming a Demon Slayer, more so to become his Tsuguko. He liked things just the way they were, but life stops for no man. Not even the Wind Hashira. And to his annoyance, this girl had been blessed by the gods with luck that never ran out. Seriously, how was she still alive?!

   Who knew saving someone's life would come back and bite you in the ass?
