Just any type of system, world-hopping type of manhwa/mangas. If possible: female protag and the story has to be meh or above. Edit: How about the Chinese kind? The system, world-hopping, because I found one called Romantic Relationships System, so I was wondering whether there were any other that is similar.
Mangas, novels adaptations: Saving 80,000 Gold in an Another World for Retirement Takarakuji de 40-oku Atattandakedo Isekai ni Ijuu Suru Isekai Izakaya Nobu The Other World Dining Hall GATE: JSDF Fought Here The last 3 already got anime adaptation
The Gamer Read this manga/manhwa(?) a long time ago. It's about some ppl having a gaming system. Stopped it couple of dozen chapters later, was awesome~
Not world hopping. There are dimensional barriers (might have a different name) that lead to pocket dimensions (or something similar), but those are created by the spirit of Earth itself, so... Good manga/manhwa(?), though. It's still going.
I read it from: Manga Rock Mangakakalot Mangago Mangadex Mangahere Kissmanga Or self-translated sites.
