Protocol: Rain

Keita Amano is a fan of one thing: gaming! Whether he’s on his phone or console, he just loves playing video games. And when the beautiful president of the game club, Karen Tendou, invites him to join, it seems like an EZ choice. Except, he declines! KO’d by the shock, Karen suddenly makes getting close to Amano her main quest. But she’s not the only one interested in him!

During a summer camp, 15 children, 8 males and 7 females, find a grotto by the sea. Deep within they discover working computers and some electronic equipment, and later the owner, a man called Kokopelli. Kokopelli claimed to be a programmer working on a brand new game, in which a large robot has to defend the Earth against alien invasions. He persuades the children to test the game and sign a contract. All but one of them signs, barely a moment later they mysteriously awaken on the shore believing what happened was just a dream.

The story takes place many years in the future where the game "Rhyme," a virtual fighting game, is incredibly popular and people possess "AllMates," convenient AI computers. Aoba leads an ordinary life, working at a junk shop and living with his grandmother on the island of Midorijima. Unlike his friends, he doesn't participate in Rhyme, nor does he belong in a gang. However, when rumors of people disappearing spread, Aoba finds himself needing to unravel the mysteries behind the island in order to protect his everyday life.
