For high schooler Akiteru Ooboshi, the whole youthful experience thing—like fun, friendships, and even having a girlfriend—is a complete waste of time. So when his best friend’s sister, Iroha Kohinata, keeps teasing him, Akiteru naturally finds it annoying. She practically lives in his room, she’s always on his bed, she’s just a raging storm of clinginess! Why is she only annoying around him?!

The verdict

Senpai’s take

Worst of the seasonBad but funFall 2025

Navel-gazing, self-aware slop about Japan's youngest indie game producer fixing manic pixie dream girl classmates, with wildly out-of-pocket subplots like fake-dating his cousin and blackmailing his teacher. Far too much going on for any romcom thread to land, and the big twist is guessable from episode 1. Characters act like psychotic aliens, but it beats therapy: three flaming dumpsters.
