Chronicles of the Demon Slayer

A brief description of the manga Chronicles of the Demon Slayer:
After brutally beheading the demon that murdered his parents and displaying its severed head as a warning, the young boy “Yi-Se” becomes feared rather than praised. Shunned by the villagers and branded a monster for his merciless vengeance, he finds himself with nothing left to live for.
With no attachment to life and no place to call home, “Yi-Se” sets out on a solitary journey… one driven not by hope, but by an unquenchable thirst for revenge. His vow is absolute: Every demon must perish. Only then will his vengeance be complete.
