Kizumonogatari Part 1: Tekketsu

The story starts following an incident: a young girl jumps from the top of a building. The image provokes a certain dread, as the girl appears to have been a corpse even before she jumped. The case is dismissed, yet more and more of these suicides occur, and all from the same building. Thus began the rumour, that a ghost inhabited the rooftop of the building.

July 1998 - After a group of delinquents is found dead in their hangout place with all their limbs twisted and torn off, Aozaki Touko receives a request to find the murderer and asks Shiki for help. The main suspect is Asagami Fujino; a girl who was the boys' plaything until recently, who Shiki believes to be "one of her kind".

After being brutally murdered in a subway station, a teen boy awakens to find himself resurrected by a strange computer named Gantz, and forced to fight a large force of invading aliens in Osaka.

Tanjiro Kamado returns home to find his family slaughtered and the lone survivor, his sister Nezuko, turned into a Demon. To his surprise, however, Nezuko still shows signs of human emotion and thought. Thus begins Tanjiro's journey to seek out the Demon who killed their family and turn his sister human again.
