H - Prologue

Bunnakit is a young medical student who can't stand injustice and denounces everything the local police hides from the public until the day he posts an article about the city's governer. Bunnakit's father, fearing for his son's life, entrusts him to a former hitman to protect him.

In addition to finding himself in the Underworld, a world that was unknown to him until now, Bunnakit finds himself trapped with Tan Wirapong, The Devil.
