>>20823024She's confirmed that she has on multiple levels, ranging from Suisei, Watame,
and Rushia as Senpais she spoke with a lot, while others like Marine, Fubuki and other Eikaiwa partners have been kind and nice to her, but are hard to pin down. Hell, Korone's a prime example, since she seems to be ghosting her a bit according to the last stream. As sad as this might seem though, there's likely a variety of factors at play that result in a lack of too many JP collabs, such as JP perception of her growth (not wanting to seem like "leeches" for their Kohai), the talents generally not jelling well together despite being incredibly nice and kind to one another, or even just the language barrier being too intimidating of a hurdle to overcome. Mori doesn't want to make them uncomfortable, and while happy to collab with them when she can, isn't dead-set on pushing or forcing them to collab with her, and will let it be
for better or for worse.All that being said, as soon as the new EN and JPs came out, she's been much more confident to flaunt that friendly use of "power" and has taken on a nurturing Senpai role, looking to connect more with the younger gens and gain their friendship more directly, with Iroha, LaPlus and especially Lui being the major standouts with JP, and NOTHING needs to be said for how involved she is with Council and Irys at this point.
While this argument doesn't completely hold up for ID2, I'd still argue that it still trades back to a matter of confidence, and her lack of it regarding in her own standing at Hololive at the time of their debuts, and didn't feel she had the standing to leverage this same aura on them, even mentioning they felt more like "sisters" to them than a Senpai. Still, she's grown close with Ollie over multiple streams, and still is friendly with Reine and Anya, though I'd love to see more engagement with all of them, really.
