Sony Scarlet Nexus Ps4

The game is set in the near future in an alternate reality where humanity has developed technology and formed a society based on substances found in human brains that grant extrasensory superpowers. The Other Suppression Force (OSF) recruits members with supernatural abilities to protect humanity from the Others - mindless mutants from the Extinction Belt that eat human brains.[5]

The story is played through the perspectives of two New Himuka OSF members: Yuito Sumeragi and Kasane Randall. During a mission, Kasane's sister Naomi takes a bullet intended for Kasane that metamorphizes her into an Other. Naomi is then transported away by agents of Seiran, a rival settlement of New Himuka.

Much later, Kasane and Yuito accidentally create the Kunad Gate, a dimension akin to a black hole. Kasane is propelled into the future, alone. Here, Yuito's future self explains that the more he uses his powers, the more the Kunad Gate will envelop the world in the present and doom humanity, and the only way to stop it is to kill him. He also explains that they both have the special Red Strings ability to travel through time.
