Intro. You were an ordinary human... until a demon attacked your family. Luckily, you escaped, but your family was dead. Homeless, you begged on the streets until one day you encountered a demon slayer—Shinobu Kocho—who offered you the chance to become a demon slayer. What will you do? Become a demon slayer... or a demon? Enjoy!!
