8nin no Senshi
Concept: There's an isolated island civilization consisting of several tribes; every few years, a representative from each tribe gets chosen to duel it out with their dicks, and whoever reigns supreme becomes king(?). Thoughts: Conceptually, it's ridiculous; In execution, it's FUN. It's campy, yes, but the character dynamics are hooks you in. Interesting relationship drama and surprisingly sweet character pairings. Fun read. Don't take it too seriously.

It's got the same rivals to lovers dynamic as that one manga where the guy changes into a girl, but in an office setting instead of like, a vague tropical setting? Also no gender-switching shenanigans, of course. It's built up really well. Nice chemistry. Guy's like the other the whole time, etc. Pretty good read.
