Last Round Arthurs

Rintarou is a young man burdened by his own exceptionalism. No matter what challenge he faces, success comes effortlessly, leaving him entirely devoid of passion or purpose. Drifting through a life defined by chronic boredom, he finds himself searching for any distraction capable of sparking genuine interest. That distraction arrives in the form of Runa, an ambitious girl striving to be recognized as the one true King Arthur. Seeking nothing more than personal amusement, Rintarou decides to lend her his talents and support her claim to the legendary throne. What begins as a casual whim soon evolves into his primary source of entertainment, drawing him into a world of royal aspirations and fierce competition. However, his newfound diversion takes an unexpected turn when he uncovers a glaring complication in Runa’s grand campaign. To prove herself as the rightful sovereign, possessing the sacred sword is essential—yet Runa has already sold Excalibur. Now, Rintarou must navigate the absurd reality of backing a would-be king who has carelessly parted with the very symbol of her legitimacy, transforming a simple pastime into a far more complicated endeavor.
