For seventeen years, Samantha Kisaragi wished for only one thing: a normal life, free from the chronic illness that made her a fragile glass doll in her family’s eyes.
One morning, her wish is granted by... a tiny, floating mochi with a god complex? This smug spectral "System" offers her a miraculous, perfectly healthy body. The price? She must now complete a series of insane missions, from the mortifying to the life-threatening.
The rules are simple: succeed and level up. Get stronger, faster, and maybe even a little more charming. But if she fails, the penalty is a fate worse than any illness: her body will warp into a 'Cursed Physique'—a seven-foot-tall mountain of grotesque muscle powered by the same old fragile constitution. A titan's strength with a body that could collapse from a stiff breeze.
Now, this former shut-in is being forced to get buff, all while juggling a top-priority quest to save her perfect older brother from a shadowy, five-star threat hunting him down. And as if that's not enough pressure, the System is also demanding she "Ignite the Flames of Passion" and make someone fall in love with her, pushing her into ridiculously close and awkward situations with her bubbly best friend.
With only a cheeky floating dessert for a guide, a terrifyingly competent senior known as the 'Ice Queen' as an unlikely ally, and a clock ticking on both her brother's life and her own romantic prospects, Samantha must learn to be a weapon. She was a girl who just wanted to be normal. Now, she has to become a monster to protect everything she loves.
