Since they were kids, Kaoru and his childhood friend Houko have had one rule: the loser in judo buys the winner a meal. But now that they’re in high school, Kaoru just can’t keep up—Houko only gets stronger every year, and he’s stuck paying the bill. Then, after one crushing loss too many, Houko teases him with a single remark… and Kaoru snaps. He stakes everything on a final match: “If I lose this time, I’ll buy you meals for the rest of my life!” A judo match that could decide their future—childhood rivalry, pride, and maybe something more are all on the line!\*

Long ago, alien creatures appeared in their town. Her childhood friend boy shielded Mechanic-chan and lost both arms in the process. She also lost her left arm at the time, but in order to repay the boy who protected her, she became a mechanic, and is now building his prosthetic arms.

Ryuk, a boy with a unique skill "Porter," which allows him to carry a massive amount of items, was being exploited as a chore boy for the S-rank party "Black Lion of Foresight."

Despairing in this hopeless situation, suddenly he meets a shrine maiden girl, Mio — and then?
