The Silver Guardian

Suigin Riku is a dedicated gamer at Shinryou Private Academy, an elite school filled with wealthy students—status he doesn’t share. Scraping by on multiple part-time jobs to cover tuition, he ends up in a dangerous situation when he jumps into a pool to rescue his cat despite not knowing how to swim. He’s saved by Rei Riku, a popular classmate and the daughter of a game developer, and the encounter leaves him captivated.

Online, Suigin spends his free time in the RPG Dungeon Century, where he grows close to a girl he meets in-game. When the servers shut down, he expects that connection to end—until he learns the next day that the girl was Rei all along. Rei soon offers him a replacement game, a tomb-raiding title called Grave Buster, but her sudden kidnapping pulls Suigin into its world. Inside the game, he fights to reach Rei while unraveling the mysteries buried within Grave Buster.
