I've had this plot running around in my head but, since I'm a busy student I don't have time/mental bandwidth to commit to it. I do however have random points in time where I can read for fun... I'm not even sure if this is the place to post this but if not, I'll take it down.
Fire Force world:
A female paramedic/firefighter from our world suddenly finds her self in the Fire Force world. She is obviously freaked out by random people bursting into flames and how the entire world seems to be ok with the collective trauma as long as there is a prayer and some fire powered people fighting the spontaneously combusted people. She also finds herself adopted by the main characters and slowly falls for one of the guys also tries to make a place for herself in this new world.
Bonus points if you can 1. make it slightly funny 2. make a joke about Lancôme (the make up company) vs latome 3. Ask why the rum is always gone
