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?
She always slacks off
whenever Yotsuba isn't around.
Sie macht sich immer ’nen Bunten,
wenn Yotsuba nicht da ist.
Ella siempre holgazanea
cuando Yotsuba no está alrededor.
Sans Yotsuba,
elle fout jamais rien.
Ela sempre se descuida
quando Yotsuba não está por perto.
