[Demon Slayer] + [Making Up for the Tragedies] + [Returnee]
Note: The protagonist's family is just as awful as Obanai Iguro's family. They'll be dealt with later. Making up for the tragedies doesn't mean there won't be any new ones.
Kuze Hibiki is a Meiji-era good-for-nothing who fled his family and the world of officialdom. His only real talent is tinkering with novel foreign gadgets. After being adopted by a former Thunder Hashira of the Demon Slayer Corps, he combines pistols with Thunder Breathing to create a unique fighting style. He isn't a genius inventor, but he is the catalyst at the heart of change. One idea leads the Butterfly Estate to develop life-saving sachets; one introduction brings modern ideas into Tamayo's research; one blueprint gives the Swordsmith Village a new weapon for slaying demons. He brings scattered geniuses together, arms tradition with technology, and rewrites fate through cooperation.
