Fireworks can be considered short lived, but it's the memory of them that lives forever. Sekien Kanosora, a boy who had never heard of Demon's gets his story intertwined with killing them. But so long as he can travel the country, kick Demon ass, and possibly (but never really) get a girlfriend in the process, he's not complaining any time soon. From Zero to Hero, this is the journey of a Hashira's rise to power, and how he became a light for everyone. Even if the costs are heavy. This story will have mild Manga spoilers. You have been warned. This is the first book that I've ever written to be an OC story, compared to my old Male Reader books. As well as being in an entirely new format. So this is a little outside of my comfort zone. Please do let me know your thoughts if you have any, and I hope you enjoy!
