I draw gay people

Both Ikemen Revolution and Ikemen Villains are set in nineteenth-century Britain. Alice (Rev's MC) falls into the magical world of Cradle after pursuing a man resembling the White Rabbit. Kate (Vil's MC) discovers a secret organization known as Crown, which harbors criminals cursed by fairytales. So what's the connection here?

Cradle's existence suggests that there may be some validity to other fairytales, providing potential insight on the origins of the Cursed. The disparities between humans from the Land of Reason and humans from Wonderland explains why magic functions differently in the two games; i.e., citizens from the Land of Reason have the ability to nullify magic from Cradle. Given the secrecy surrounding the Cursed, it's reasonable to assume Alice would be unaware of Crown's existence, hence why she's frightened by magic. Likewise, it's understandable that Kate wouldn't know about Cradle, regarding Alice's Adventures in Wonderland as only a work of fiction.

What about Ikemen Sengoku and Ikemen Vampire? Vampire is set in nineteenth-century France, whereas Sengoku takes place in... the Sengoku period. Shocking! Despite this, their connection is more apparent than the aforementioned games. Mai (Sen's MC) is taken from modern-day Japan to Sengoku-era Japan when she accidentally encounters a wormhole. Mitsuki (Vamp's MC) is transported from modern-day France to nineteenth-century France after she mistakenly enters a portal. In short, the time travel narratives share similar characteristics, leading me to believe it's the same world.

Lightning round. I already have to suspend my disbelief to accept the existence of fairytale magic, so why not do the same for time travel? Technically, Alice arrived in Cradle via a gateway, which she did again in the Looking Glass route sequels. Said gateway confirms dimension jumping is possible in Rev, connecting it to Sen and Vamp. Furthermore, if the Cursed can exist, then why can't vampires? Though the canonical nature of the story can be questioned, I faintly recall a Halloween event where Crown transformed into undead beings with a taste for humans. That sounds exactly like vampires.
