episode 4 (S01E04)

Young men and women are lured to the enigmatic "Hotel Requiem," a sinister establishment run by the Corvin tribe, where they are treated like livestock. As they fight for their freedom with guns and swords, they quickly realize that every attempt to escape is thwarted by the relentless Corvin clan. K (Natsuho) secretly teams up with Noah, a former member of the Corvin tribe, to rescue Manami (Totate Asae) and lead her to the depths of the underground Dracula clan. There, the shocking truth about Manami's origins unfolds: she was one of three children born during the Grand Cross in 1999, while the other two, burdened by their ancient blood, met tragic ends. K was sent as a messenger to bring Manami to this fateful place.
