I think you can be interesting or entertaining without being clippable etc. Nijisanji has a space to be filled for the soft and comfy Ina-esque streamer, and I think she can definitely fill that niche as she is.
Unfortunately, her stream times are massively unfriendly to EU, which means she's always banking on JOPs to fill in for an audience that Selen and Rosemi are able to capture more frequently. The title of her recent MK8 stream stood out to me, too, called 'i won't lose!!!!!!!!!', the kind of title you'd expect from a Japanese streamer using broken English even though we know she's fluent English.
I don't think bilingualism and self-translating for your audience is a skill you should refrain from using, but it IS a balancing act that she's leaned too heavily to one side on. This is to say nothing of the fact that, probably due to timezones, Rosemi is able to barge into Selen and Finana's APEX collab where Petra is yet to engage with any of the other 5 in such a way outside their wave collab.
Sincerely, I hope she's able to find her footing. She's playing unique games and doing different things which is good. That doesn't necessarily translate into raw views, though. Rosemi is in a similar predicament of still trying to figure out what she wants to be. We see this kind of thing very often with new V-Tubers.
