Aki

A random ghost who joined the Skybreakers to alleviate her chronic homelessness problem. Originally from a place called Limbo, which is basically another one of these everyone-gets-isekai'd universes except much more dour and only for losers, she offers the really limited role of "can make people spooked". She's not even that good at it.

Biography
In short, she died and doesn't remember much about anything back when she was alive. Then, she was a ghost for a long time, and with her sister they spent their time doing ghostly things like "slightly moving chairs around" and "whispering but only when it could be plausibly explained as a natural phenomena like a TV being left on or unusually chatty house acoustics". Then she got exorcised. Doesn't like talking about that.

The majority of her life...er, afterlife was spent in Limbo, which isn't really like the normal one in any way and is just for those few people that both Heaven and Hell didn't want for some reason. I.E. Losers.

She is an industrious lady, and got a lot done. Most of it revolved around guiding those who recently entered Limbo into a more stable state, and being the sales clerk at a record store.

Then she got kidnapped by the usual bullshit and now is in a big crossover RP. Yaaaay.

Personality
Likes to exaggerate and make up stuff.

Swordsmanship
She learned how to hit people with a sword via practice. Like, not even with references or mentors or literally anything to go off of beyond like one worn reel from ''Seven Samurai. ''It's a miracle that she has any skill in it at all. I mean, really, it's probably because she's practiced for a few hundred years.

Ghosty Illusions
Aki's a ghost, right? And she knows how to do stuff that scares people. She's honed it enough that she actually can do more than whispering scary things in people's ears, like creating ghastly images and hiding people and still whispering like before. Doesn't really scare people, though.

Lame Magic
She says she can do literally anything with magic, but all she can actually do is cooking and housework because she's too lazy to do it the normal way.
