Synopsis
Subarashiki Kono Sekai The Animation follows Neku, a cynical teen who wakes up in Shibuya with amnesia and the ability to read minds via mysterious pins.
He soon discovers he's a Player in the Reaper's Game, a seven-day competition where participants must complete missions to avoid being erased.
Neku teams up with Shiki, another Player, to battle dangerous creatures called Noise and uncover the secrets of the Game while fighting for their survival.
As they navigate the challenges, they encounter other Players and Reapers, each with their own agendas, adding layers to the unfolding mystery.
Ultimately, Neku and Shiki must learn to trust each other and work together to overcome the Game's trials and understand why they were chosen to participate.
