High school student Ayane Tanihara logs into the virtual reality online FPS game Assault Addict to rescue her missing upperclassman, a senior she admires who disappeared while trapped inside the game. She forms a team with three other players to navigate the dangerous virtual battlefield, but each of her companions harbors their own hidden motives and secrets. The missing senior also possesses a mysterious side that complicates the mission. As they search for the senior's avatar, a character named Angie, the team must clear increasingly difficult combat stages while facing internal conflicts. During their journey, one teammate named Kaede confesses to having mistreated the missing senior in the past, creating friction between Kaede and Ayane. Before they can locate Angie, the next mission begins and enemy tank units appear before them as their interpersonal tensions reach a breaking point. The cyber-military action story unfolds across a blended reality environment where an online FPS game becomes a life-or-death battleground, forcing the high school girls to confront both external enemies and their own complicated relationships. The complete manga spans three volumes, following the team from their initial deployment into the virtual battlefield through to the resolution of their mission to free the trapped school council president.
