Tenshi (Kanade Tachibana) originates from *Angel Beats!* but integrates into a crossover series' shared setting. Her background as a deceased student in the afterlife is acknowledged, recontextualized within a comedic environment. She maintains her reserved, stoic personality, consistently displaying calmness and minimal emotional expression, contrasting sharply with surrounding chaos. She arrives in Season 2 alongside the Afterlife Battlefront (SSS), led by Yuri Nakamura, who declares their intent to destroy this world and confront its creator. Initially aligned with this goal, she participates in schemes targeting the world's structure or inhabitants. Her abilities include summoning clones and unleashing destructive power, notably triggered when her mapo tofu is ruined, causing widespread damage to environments and participants during events like fighting tournaments. Throughout the series, she frequently interacts with Kagari from *Rewrite*; their similar appearances and voices lead to shared scenes highlighting parallel characteristics. As the SSS engages in repeated comedic failures—failed bus hijackings, ineffective confrontations—their rebellion weakens. By Episode 21, many SSS members, including her, abandon their antagonism, joining group activities and forming bonds. This shift demonstrates her tacit integration into the community without overtly rejecting her original mission. Her development concludes by emphasizing coexistence over conflict. In later episodes, she collaborates with Yuri and others during the cultural festival, showcasing reluctant but tangible acceptance of the world. Her arc ends without returning to destructive objectives, instead cementing her presence within the ensemble.
