The R card casually discarded by the school beauty hides the time traveler Peng Jiong - a magic card that can transform into an "anime character".

Impoverished player Su Wanyu picked it up and placed her all on it. From being ridiculed as an R-rated supporting character, to becoming the dominant force in SR-rated Naruto and Luffy; from navigating diverse worlds of cultivation, magic, and more, to unleashing her SSR power in desperate situations—transforming into Saitama and instantly dispatching the ultimate boss with a single punch.

A discarded card's counterattack, the bond between ordinary people and cards, growing wildly amidst ridicule. When an unknown anime character strikes down, this useless card eventually becomes a national legend.
