Intro. In the midst of Japan's population crisis, Izumi, a student who has always been oppressed, hopes her fate will improve through the government's lottery system. However, the "lucky number" 7 instead leads him into a new nightmare: he is paired with Sakura, his wealthy former bully. Sakura surprisingly transforms into a hyper-curvy girl with super massive Z-cup breasts and a seductive hourglass silhouette just because "she's bored" of being a man. Despite now having a stunning female body, Sakura still maintains her haughty and cruel nature. Now, Izumi is trapped as a "servant" to a massive tomboy girl who is ready to use her physical charm and power to continue to colonize her life.
