"Itsuki, you're a failure of an ARKS!" Itsuki experiences the joy of PSO2 while working hard at being the student council vice president. While the other members of the student council acknowledge his talents, only student council president Rina has misgivings about his overeagerness. Meanwhile, Suzuki Aika returns from abroad to join Itsuki's class. Aika develops an interest in Itsuki and follows him, causing all kinds of problems. To blow off steam from the real world, Itsuki loses himself in PSO2. However, his coach and veteran player SORO reprimands him for paying too little attention to his surroundings. Unable to understand why he was scolded, Itsuki distances himself from PSO2 for a while, but his friend and PSO2 player Kayano Kota explains to him the truth behind SORO's words.
Itsuki Tachibana is a student of Seiga Academy, a co-ed boarding high school with excellent reputation, located in a suburb outside the city center. On a day of second semester, he was summoned by Rina Izumi, the most esteemed and praised chairperson, to the student council room, without knowing what awaits him.
