- Ear Worm: The first season opening. Kake-kake-kake-kake-kakete!
- Les Yay: Along with romantic tension in general, is in the air when Arashi has to do a kiss scene for a visiting mangaka in need of inspiration.
- Moe: Yayoi, full stop. And Jun, both versions.
- Narm: Jun's extreme freak-out when she witnesses a firebombing in WWII Japan is way too long and just not scary enough.
- What an Idiot!: While spending time in Jun's body, Hajime realizes his balls are gone and his chest is bigger. Surely the balls fell off somewhere.
YMMV / Natsu no Arashi!
