ぐうたら巡洋艦ヨシノの勘違い英雄譚
Guutara Jun'yōkan Yoshino no Kanchigai Eiyūtan
Yoshino just wants a quiet life: eight months of fuel in her tanks, a comfy hammock on deck, and absolutely no paperwork. Unfortunately, she got isekai'd as a heavily armed warship girl into a fantasy ocean where sea monsters eat trade fleets, kraken haunt the shipping lanes, and every port has a Guild that thinks "adventurer registration" is a great idea.
Enter Yuni, her brutally honest seaplane partner, who drags her out of bed, shoves her into that Guild, and accidentally helps her blow up enough things that the world decides Yoshino must be a legendary male explosion mage with a genius bird familiar. (Yoshino is not a man. Yuni is not a bird. The broad-sheets do not care.)
Now, while dodging rumors, pirates, and way too many kraken, Yoshino and Yuni chase the ultimate prize: absolute, peaceful silence. From scooping crude oil by hand to fighting oil slimes and jury‑rigging filters, they'll do anything to turn this dangerous sea into their personal convenience store.
