S Rare Soubi no Niau Kanojo

Seko Daiko is a second-year high school student defined by one overwhelming trait: he is an unapologetic cheapskate. His relentless dedication to frugality knows no bounds, driving him to extreme measures just to save a few extra coins. Whether it means unscrewing every light bulb in the house to cut down on electricity or forcing his siblings to eat nothing but baked bread crusts for breakfast, Daiko treats penny-pinching as a serious way of life. For a long time, he firmly believed that this ultra-thrifty lifestyle could continue indefinitely without any consequences. He had mastered the art of avoiding expenses and saw no reason to ever change his habits. However, his carefully constructed world of absolute financial restraint is suddenly turned upside down by an impossible scenario. In a bizarre twist of fate, the very survival of the world now rests entirely on Daiko's shoulders, with one unthinkable condition: he must spend money on a mobile game. For a boy who has built his entire existence around saving every last cent, being forced to open his wallet to prevent global catastrophe presents a hilarious and agonizing dilemma that challenges everything he stands for.
