Mukiiiii~ if I'm being isekai'd into a magical world, first off, you're one of them that's coming with!

Ideally, I'd prefer it be a peaceful world wherein we have to accept this is our lives and rebuild what we can. If it was a war turned world wrought with danger, I'm not sure how happy I would be about it because, even say my close friends get plot armored from fatalities, there are chances of making friends here and losing them, which I think would be too painful for me to accept in a world like that. Though, if we're talking war as like a flashy competition (like in the anime Dog Days) then I could probably deal with it better!

Going back to a more peaceful world, it'd be like a challenge, hopefully we're not going too far back to like stone world levels of "rebuild life", but I do like the idea of trying out a new world, probably of a medieval setting or since it's less frequent, maybe a sort of sci-fi future that has a magic mix! I think a world like that would be neat! Part of it would also be because, while I'm not a story writer and don't make interesting tales, I have been brainstorming a world (or two) around my characters, one being Anthro Leaf who does live in a futuristic cyberpunky setting, so it's really easy to imagine wanting to be in a world I'm developing in my head, though under a more peaceful situation than the story focus I've given my own character!

If lightning could be an element, it's something Leaf would have, he could shoot shockwaves with his fists, but also he can be an on-demand battery where he'd try to utilise a guitar with mini-speakers in his camo pockets to play music on the go, maybe work it into his fighting style defensively and offensively! And he can serve as a means of blackouting or giving charge to areas that have or lack electricity, his uses would be endless! Alternatively, an unexpected element would just be anti-magic, the ability to neutralise magic which would canonically explain Leaf unable to use magic, and would come with complications in its utilisation which, unless a technology is powered by it, wouldn't be affected by such an element. Otherwise, he'd just keep building on his own fighting skills! (I know I keep saying Leaf as though to distinct him from me when in this case I'm supposed to be him, I'm just used to referring to him as the character!)

To try and answer in a short way, the ideal scenario would be some kind of sci-fi fantasy world, one where technology exists and perhaps magic! Preferably one in which isn't at war or going through some kind of political or corporate crisis, though some kind of adventure or series of circumstances would still be nice to go through as a kind of trial to earn our right to enjoy this life, we wouldn't want it to be too boring if we have it easy right away! Sorry if it's a lot of rambling to get to the answer you wanted ^^;
