One day, high schooler Ageha Yoshina picks up a mysterious “red phone card” left behind in a public telephone booth.
A few days later, his childhood friend and classmate, Sakurako Amamiya—who possessed the same card—suddenly vanishes without a trace. In search of her, Ageha finds himself drawn into the rumors surrounding a nationwide string of mysterious disappearances, said to be the work of a secret organization known only as “PSYЯEN.”
When he accesses the group, a deadly game begins—one that will change his fate forever.
Mysterious tombs appeared all over the world one day, each containing a relic which grants its owner supernatural abilities. Jooheon Suh is a tomb explorer, excavator, and raider. Betrayed by his employer, he's about to die at the hands of a powerful new relic when he suddenly finds himself 15 years in the past, before any relics or tombs made their debut. Driven by feelings of revenge, how will Jooheon use his knowledge of the future to become the Tomb Raider King?
