The game "Girls Breakers" is a mysterious title rumored to grant eternal life upon completion. When her older sister, Haruka Akina, goes missing after entering the game, Manatsu resolves to obtain the game and venture inside to save her. The first enemy she encounters is Ralfas, a special effects martial artist who controls electricity. With no combat experience, Manatsu is quickly defeated and punished by having her body violated instead of being revived. Defeated repeatedly by successive enemies and subjected to relentless torture, Manatsu struggles desperately to survive until she finally reaches the final boss, Berga. However, overpowered by his overwhelming strength, she is crushed and meets the worst possible ending.
