The Deadweight at the Jujutsu Academy

Hagiwara Kazuyuki attends Yokohama Jujutsu Academy, a school full of powerful people, but he's useless and can't do anything. One day, while walking in the forest, a curse with a scar on its face fell right into his arms of its own accord. His underclassmen: "Hagiwara-senpai is amazing! He caught the most evil curse!" Hagiwara Kazuyuki: "??? I didn't do anything." After that, whenever he went for a walk outside, curses would kneel at his feet and beg for mercy. Whenever he browsed the storeroom, he'd find high-grade cursed objects that had been left behind. A few months later, the useless guy who couldn't do anything made it to the top of the school rankings and became the best student at the jujutsu academy. Hagiwara Kazuyuki: "??? I really didn't do anything." Only later did he learn that while he was utterly useless, he had absolutely incredible luck. Then he discovered that, for some reason, all the powerful people liked him, useless as he was. Theme: But lying flat is shameful.
