Online! The Unbeatable Game, Vol. 1 — Midori Amagaeru

It's not about winning… It's life-and-death!

One by one, students stop coming to school, and rumors spread that a cursed video game is behind the disappearances. Mai Yashiro wants nothing to do with it, but then a mysterious console appears in her bag. A creepy voice gives Mai a choice: play the game or lose everyone she cares about. She chooses to protect her loved ones, but any sense of relief is short-lived. It turns out dying in the game has terrible real-world consequences. Thankfully, she's not alone, and she teams up with her schoolmates Asagi and Sugiura to beat the game. The odds are stacked against them, but they're playing to win -- even if they have to risk their lives!
