Hensuki: Are you willing to Fall in Love with a Pervert, as long as she's a Cutie?

One day, a love letter shows up in Keiki Kiryuu's club room — sweet, right? Except it also comes with a pair of white panties. No name, no explanation — just underwear and a confession. Now Keiki has to figure out which girl left them, and his investigation into his so-called 'Cinderella' goes sideways almost immediately. Every suspect — his calm senior Sayuki, the prim underclassman Yuika, his classmate Mao — turns out to have her own very specific and very unexpected fetish that she's not great at hiding. What starts as a romantic mystery quickly becomes Keiki stumbling from one awkward revelation to the next, trying to keep his composure while the girls around him absolutely do not. This 12-episode TV series from 2019 (studio Geek Toys) is adapted from a light novel, and it leans hard into the comedy side of its ecchi premise. The fetish stuff is played for laughs rather than anything too serious — it's more absurd than raunchy. Each girl gets enough screentime that the harem setup doesn't feel like a revolving door, and the mystery of who actually left the letter gives the whole thing a throughline beyond just gags. If you liked Shimoneta for its shameless humor or got a kick out of the chaotic energy in Aho Girl, this hits a similar wavelength. Tejina-senpai fans will also recognize the vibe of a guy surrounded by girls who are endearing precisely because something is a little off about each of them. It's light, it's dumb in the best way, and it knows exactly what it is.
