#marina or aeon get him some kind of communication device to keep in touch

[sadlynotthevoid]

Ngl, the Ark of Miracle Nikki sounds like the perfect way to get characters transmigrate from a world to other.

I mean, imagine most people from TBOAH getting suddenly teleported into a massive (techno? magic? fashion inspiration fueled?) flying ship, which can travel through the space-time, because "your world is doomed because of an asshole. We're so sorry. Please feel free to use the facilities and rest until we arrive to your new home".

Besides, I would really like to have og!Cale befriend Aeon and Marina. They would get along, specially having in count that "new world" means their nobility is nothing. He wouldn't need to hide himself and they aren't from his world, so no precoinceived ideas.

Besides, Marina is a kid. Og!Cale would look at this cheerful lively kid and wouldn't be able to hold back his big brother instincts. "She's a lot like Lily when she was a toddler", he probably would think. (Because, yes, I headcanon that og!Cale spent a lot of time with Lily when no one was around and she was still "too young to remember". Lily isn't sure whether she dreamed it all or not)

And imagine Aeon introducing modern music to og!Cale. Og!Cale, who may had learned music when he was a kid (classic noble kid activity), liking many of these various styles of music, all so different from the elegant ones the noble likes and the vivid ones he heard at the streets and bars. Then Marina telling him that Aeon also writes songs, but warning him not to listen them in a way too serious tone (she's such a gremlin).

And between all that you still have the tboah characters aclimatizing to the idea of a new world, fixing relationships, and planning what to do now that their status mean shit (poor royal family. Ha.)

Just a transmigration story where the characters have time to talk with their family and adjust before being send to other world.

Maybe the world they're going to is the Soo's Earth. One that is on its way to recovery, but has way less population than before.
