Yuzuru Otonashi features in the crossover *Kaginado* as a member of the *Angel Beats!* ensemble. He appears in a chibi style alongside characters from *Kanon*, *AIR*, *CLANNAD*, *Little Busters!*, and *Rewrite*. Within *Kaginado* Academy, he is part of the Afterlife Battlefront (SSS), led by Yuri Nakamura. The SSS initially engages in comedic rebellion against the world's order, aiming to destroy it and confront God, but their efforts consistently fail, appearing inept and absurd. Over time, Otonashi and the SSS integrate into the academy's daily life, participating in group activities and school events like sports tournaments and cultural festivals alongside characters from the other series. By Season 2's later episodes, Otonashi and his SSS comrades form friendships with non-*Angel Beats!* characters. They shift from Yuri's goal of world destruction to supporting these new friends during conflicts and competitions. This integration culminates with the SSS actively cheering for their friends in a fighting tournament, signifying their acceptance of the *Kaginado* world. Otonashi's presence remains primarily as part of the collective SSS group, without unique dialogue, actions, character development, exploration of his backstory, personality traits, or relationships from *Angel Beats!*.
