So you are finally awake...

After you passed out somewhere else... a certain black-haired 15-year-old with a heart of gold and mature personality brought you into her own shophouse.

Let me introduce myself: My name is Rikka Takarada and I'm a member of the GRIDMAN alliance, I work alongside my friends Yuta Hibiki and Sho Utsumi so we can summon the interdimensional superhero known as GRIDMAN and fight against the Kaiju that invade us so we can protect our world.

How about you?
