Chihaya Kisaragi features in the spin-off *PUCHIM@S*, primarily focused on caring for a Puchidol named Chihya. Miki Hoshii discovered this Puchidol on a tropical island, and Ritsuko Akizuki assigned Chihaya as its caretaker. Chihaya initially balks at the responsibility, citing its demanding nature. Yet, she grows increasingly fond of Chihya, ultimately deciding to adopt her permanently. A running gag sees Chihaya persistently trying to name Puchidols "Gonzales," only to have her suggestions consistently rejected.
