   Summary

   What if Isagi was a water-breathing user and trained in it before he joined Blue Lock?
   What if the descendants of the other hashiras teach their breathing styles to others?
   What if Isagi's family traditions catch up to him while he's in the facility?

    

   I'll be editing and adding to the story cuz I feel like things are missing and the chapters seem too short.
