Based on ZZZ/SL: Apex Predator by Saeko_Kaburagi on WN and Reincarnation Station or whatever its called
R!Belle = Reincarnated Belle ps. Belle is not a perv like in the story above
Harem R!Belle x Kafka x Arrlecchino x Ei x Evelynn(zzz) x whoever
It's all the Hoyo verses in one (honkai verse with zzz being a world with tyvet a different dimension that u need a specific lost gate to enter with the Archons being the only ones in that dimension knowing this, gates only appear on the ZZZ world) and R!Belle has a system that changes the gates she goes in to other worlds this is where others from title comes in (the gates only change when Belle herself goes in) and streams her adventures to potential allies so she can make her own team which the main team ends up her harem the system is only a progress tracker and team management type not counting the stream functions belle can bring anything back(includes people) but it has to be within her relative strength range and she can train people in other worlds power systems but it has to match that person and she can repeat/continue gates though Wise is still her proxy.
