It's Impossible to Have a Secret Crush on Saiki [Crossover]

Kumoja Satsuki has the superpower to "turn into a bird every night." She always thought the ability was useless, until she met Saiki. "Chirp, chirp, chirp~" Even though I fly over to sneak a look at you every day, I absolutely do not like you. "Chirp, chirp, chirp!" Don't you dare touch my head! I'm super fierce! The psychic Saiki has a free-range skylark who only appears after six in the evening, and every day the bird enthusiastically confesses her love to him. She doesn't know that her identity has been exposed for ages. [Good grief, even if I turn into a male bird, I'm not doing a courtship dance.] Pairing as described in the blurb.
