>>97443274Shiori is Alice because she is both black and white themed like a chess board and reads books, hence she is the one who enters the story, the protagonist (also she is victorian era girl coded in general)
Biboo is the White Queen because obviously she is white/silver colored and also has a vaguely royal/ojousama-esque design and a crown, her ability makes people her subjects but she is mostly benevolent
Nerissa is the Queen of Hearts because she is evil-coded being a demon and has a dominating mistress vibe as well as literally ruling over people's hearts
FWMC being Tweedledee and Tweedledum is self-explanatory
ERB being the Red Queen is also self-explanatory; red, a leader, a regal brit named Elizabeth
CC is the Mad Hatter because she is victorian era teaparty-themed and drinks tea, has a wacky, teasing/sadistic personality
Raora is the Chesire Cat because BEEG CAT
GG is the March Hare/Dormouse because she is the Mad Hatter's sidekick and is generally small animal/mammal-themed in appearance and is crazy, like a mad march hare
