Protocol: Rain

Shun Tokinoya is a second-year high school student living with his mother and younger sister. Following a tragic accident that claimed his father’s life and left his sister injured, Shun abandoned the competitive video game he once loved. Now dedicating himself entirely to his studies and a part-time job at an esports café named FOX ONE, he spends what little free time he has reconnecting with his childhood friends who share his gaming background. His quiet routine shatters when he discovers that FOX ONE is burdened with massive debt. Determined to save the establishment, Shun and his friends set their sights on the Xaxerion Championship, hoping its grand prize will provide the funds needed to clear the financial ruin. Carrying the heavy weight of guilt over his family’s tragedy, Shun forces himself back into the competitive online gaming world he swore to leave behind. His return quickly draws the attention of Bakuretsu-kun, a former teammate from his past, setting the stage for intense rivalries as Shun fights to secure his family's future and redeem himself in the arena he once walked away from.
