[Hider=Idea 5 - Reverse Isekai]Fifth up is something that probably works best in a 1x1 scenario. It's kind of like a reverse isekai.[hr]

Basically, instead of random Japanese teen getting merked by an isekai truck and transported to a magical realm where everyone has cool magic and superpowers, it's someone from [i]that[/i] realm getting killed by like, a falling boulder or something, and they are instead transported to the modern day. 

One of us would play the person from the modern day, while the other is from the other realm. Said person from the other realm would still have their magic and any sort of equipment on them, but struggle to adapt to modern technology and society. Meanwhile, the person from modern day would probably act as a sort of guide for the other, and would have to teach them about how things work in the modern era.[hr]

That's the basic premise. There are all sorts of variables we'd need to figure out and create. Like where does this take place? Tokyo? Chicago? Somewhere in Rome? Or what kind of world did the other person come from? Somewhere high fantasy with dragons and sorcerers? Somewhere with Magitech like airships and magical tools? The options are abundant, and you could play this anyway you wanted. [/Hider]
