Kyousuke Natsume appears in the crossover series *Kaginado*, depicted in its signature super-deformed, chibi art style while retaining recognizable features like his auburn hair and red eyes. He maintains his role as the charismatic leader of the Little Busters group. The series places him in comedic situations alongside characters from other Key franchises, including *Kanon*, *Air*, *Clannad*, *Rewrite*, and *Angel Beats!*. In the first episode, "The Climax, Etc.", Kyousuke participates in a baseball game with fellow Little Busters Masato Inohara and Kengo Miyazawa. He hits a home run and then says farewell to Riki Naoe. This goodbye escalates into a comedic physical altercation when Rin Natsume objects to its length, sparking a fight over Riki's attention. *Kaginado* focuses on lighthearted, episodic meta-humor rather than exploring Kyousuke's original complex background or narrative arcs, such as his creation of an artificial world to prepare Riki and Rin for tragedy or his self-sacrifice to prevent a bus explosion. His personality traits—his tendency to propose absurd ideas and his role as a guiding figure—are presented in a simplified, humorous manner fitting the crossover's comedic tone. His inclusion is part of an ensemble cast; his appearances are brief and center on parody or situational comedy, not character development. This includes meta-commentary, like scenes where characters debate the meaning of the title "Kaginado" itself. His original story elements remain separate from the *Kaginado* narrative.
