Demon Slayer: Crimson Veil

The year is 1650, 133 years after the death of Yoriichi Tsugikuni, the progenitor of Breathing Techniques. The battle against Muzan and his Demons is as fierce as ever. The Demon Slayer Corps is slowly expanding, gathering new members every day. One boy, an orphan raised by the Corps, is regarded as a prodigy. He killed a Demon at the tender age of six and created his own Breathing Style at the age of twelve. The boy was highly respected, but many of the members, especially his master, the Flame Hashira, worried about his mentality. He did not flinch at death, nor did he mourn those whom he was close with. But, he begins to change bit by bit after a chance meeting during the Final Selection.
