Subarashiki Kono Sekai The Animation

In the bustling city of Shibuya, Neku Sakuraba finds himself holding two black pins that give him the ability to read minds and see "Noise," hostile creatures capable of erasing people from existence. After realizing he is trapped in the city, he receives a message about a mission that will erase him if he fails.

Trying to fend off a Noise attack, Neku meets Shiki Misaki who asks him to form a partnership pact with her to fight against the monsters. Shiki reveals they have become "Players" in the "Reaper's Game," an event that stretches over seven days and each featuring a different mission.

Neku and Shiki strive to survive each day and meet other Players and Reapers, battle stronger Noise, and uncover the mystery behind the game. As they progress, they must do whatever it takes to finish the mission and survive the Reaper's Game.
