Yuta Hibiki wakes up in the home of his classmate, Rikka Takarada, with amnesia. A voice from an old computer, identifying himself as "Gridman," has a mission for him, but can he even survive the next day of school without his memories?
--Yeah, I keep seeing and hearing things.
--Remember your calling.

– Non, c’est l’hallucination…
– Remémore-toi ta mission.
-Sim, continuo vendo e ouvindo coisas.
-Lembre-se do seu chamado.
