致同桌的你

Can be done in Simulated Universe 6, during your first encounter with Cocolia in story, or in Forgotten Hall 15. You have a fraction of a second to reset the game and retry the battle if some other unit defeats Cocolia. NOT possible in Echo of War.

Spoilers warning... Serval was Cocolia's best friend as they shared a passion for rock music. The fact that Serval has to deal the final blow against the human version of Cocolia (and not the transformed version) depicts a personal and heartfelt conclusion to their relationship. The Chinese version (致同桌的你; roughly translates to "To you, my deskmate) could be a reference to an article of the same name from Yanbian University News, written by Wang Xuechen. It's written in the style of a letter addressed to the writer's friend, with the writer reminiscing about how much fun they'd had together, how much they miss their friend, and how they look forward to seeing them again. It could also be a reference to the Chinese young love movie 同桌的你 (although the rough translation says My Deskmate, the English title is My Old Classmate). It follows the story of Zhou Xiaozhi, a quiet and delicate transfer student who meets her deskmate, Lin Yi, a naughty boy who sits in the last row in class, and experience their time in junior high, high school, and college together.
