恋する極道おにいさん [Koisuru Gokudō Onii-san]

A short, three-issue comedy manga from Square Enix (2021–2022), Koisuru Gokudō Onii-san follows a yakuza enforcer whose tough-guy exterior crumbles when he falls head over heels for a sweet-natured office worker. The series plays its absurd premise straight, leaning into the contrast between violent underworld posturing and flustered, puppy-dog romance. While brief, it's a polished example of the "yakuza in love" subgenre, delivering its laughs and heart in a tight, self-contained package.
