There is no connection between the various chapters. There are some fans of the game, such as You Imprisoned in the Palm, [the three male protagonists Haruto, Aoi, and Chiaki may all appear], Love and Producer [well, Old Man Li, Powerpuff Girls, Golden Retriever Star, and Professor Black are all possible], Onmyoji [emmm, not necessarily], Touken Ranbu [not necessarily possible], Chu Liuxiang [recently deleted from the game. . . May appear less], Academy K [have not finished conquering yet, have conquered Little Black Red King Qingwang, Fuximi ing] and so on.
There are also some less popular anime or childhood memories, such as ben10 [may be integrated into British and American dramas], and super armor [emmm. . ], The Adventures of Jackie Chan [It depends on the situation], Douluo Dalu [I have thought of a few interesting martial arts spirits recently. . . ], Battle Through the Sky [This is so long ago that I almost forgot about it. . . ] I will add more when I think of it.
