In the near future, technology has developed to the point where most things have been digitized, from everyday items to entertainment. Makito is a game-loving student who is full of curiosity. He tries every game that comes out, but he had lately been dissatisfied with them. One day, he received an invitation to the closed beta of an augmented reality (AR) game called ‘Harvest Onreal’. It was the highly anticipated newest work by Cymell Corporation, which had produced the prominent AR game ‘Cherry Blossom’. He was very excited to play it even though he had never seen a game labelled as a ‘live game’ genre before. He signed up for the game without reading the user agreement at all and later found out that he could not exit the game nor turn off the AR. Makito got others around him caught up in it as well: game-loving lady-like underclassman Lilia, the most powerful (and short) upperclassman Komachi, transfer student Yuuka who he met by chance at the beach, and his genius programmer younger sister Sumi. They gathered together as the ‘next generation club’ with the goal of clearing the game.
