   • no happy ending

   Summary

   The water hashira’s tsuguko does not practice water breathing. It should be scandalous, but then again, the Demon Slayer Corps have seen worse.
   Hinata Shouyou’s first impression of Kageyama Tobio is, cold. His second impression is, strong.
   Or, the Demon Slayer AU
