Terfa

Terfa appears to be perpetually unimpressed with the world around her. Well, worlds plural, because somehow she and a friend (Flavia) fell through a portal to another world (Mixolys), where they have been mistaken for some strange variant of the local creatures (Pactones). They've also fallen into Medlia, where they were treated with less miscommunication (but they did get stuck with immigration paperwork). Neither of them are sure why they're being yanked across the multiverse, though Worldseal may be able to provide a solution for them. However, it seems the world transfer process scrambled Terfa's memories some...

Basically, Terfa is a Kuudere-type but with a more sarcastic edge. Maybe she misses what she remembers of home?
