Kotomi Ichinose appears in the crossover series Kaginado, retaining her core traits while adapting to its comedic ensemble style. She sports her signature indigo hair in two small horsetails secured by pink beads. Exceptionally intelligent yet socially awkward, she is often found reading complex materials in the library. Her infamous violin playing, causing listener distress, remains a recurring gag. Her background includes the tragic childhood loss of her parents in a plane accident, which led to prolonged isolation. Academically gifted, she consistently ranks in the national top ten across all subjects and reads foreign language texts proficiently. Within Kaginado's multiverse, she interacts with characters from other Key series. Her close friendship with Tomoya Okazaki, originating in childhood and rekindled in high school, remains significant. The series acknowledges her eventual relocation to America for advanced studies. Kaginado portrays her adult life, showing her romantic relationship with Kyou Fujibayashi culminating in marriage. Together, they adopt a daughter named Aina Fujibayashi. Her thematic connection to parallel world theories, referencing her parents' research, surfaces as she discusses these concepts. Her behavioral quirks persist, including speech patterns ending with "nano" or "no" and quoting literary works like Robert F. Young's *The Dandelion Girl*: "Day before yesterday I saw a rabbit, and yesterday a deer, and today, you." The parody format amplifies aspects like her violin playing (transitioned from trauma response to joke) and her social awkwardness/genius for humor when juxtaposed with characters from different universes.
