I kind of think it that way. Sora is the idol (dancer and singer) type but leans toward JP audience, while the respective VSingers AZKi aligns/clicks with JP and Suisei has more chances with kaigai-nikis. IRyS on the other hand, is more of EN introduced to JP but accomodated to EN viewers/listeners.
Its padoru-padoru season after this halloween
Suisei has a surprisingly large fandom of kaigai-nikis. I think she has an idea of it, given her English-only karaoke & her duolingo streams, though those are all a long time ago.
I remember the hololive subreddit had some guys that collected all livechat over 3-4 months and Suisei had 3rd or 4th most English speakers, after Coco, Akirose and I forget the 3rd, if she was fourth.
Coco's meme review with Suisei also had more viewers than normal.
and if we look at Holotalk, going by release date, these are the view numbers.
1. Marine (590k views).
2. Fubuki (500k views).
3. Shion (350k views)
4. Subaru (417k views)
5. Miko (324k views)
6. Mel (220k views)
7. Aki (204k views)
8. Suisei (325k views)
9. Roboco (181k views)
10. A-chan (388k views)
11. Kiryu Coco (422k views)
12. Matsuri (274k views)
13. Tales of Arise (91k views)
14. AZKi (152k views)
15. Haachama (171k views)
16. Sora (185k views)
17. Choco (141k views).
if we look over it based on viewers instead.
1. Marine (590k views)
2. Fubuki (500k views)
3. Coco (422k views)
4. Subaru (417k views)
5. A-chan (388k views)
6. Shion (350k views)
7. Suisei (325k views)
8. Miko (324k views)
9. Matsuri (274k views)
10. Mel (220k views)
11. Azki (204k views)
12. Sora (185k views)
13. Roboco (181k views)
14. Haachama (171k views)
15. Azki (152k views)
16. Choco (141k views)
17. Tales of Arise (91k views)
Obviously Marine and Fubuki got a huge boost for being the first 2 guests. Though given their popularity overall I think they'd be among the top regardless. Coco was during her graduation, so a lot of people tuned in. But again, Coco had a massive English following for obvious reasons, and would no doubt get numbers. Surprised by Subaru being where she is, A-chan makes sense given she's basically able to answer very interesting questions. Shion was third, so got a boost.
Also to note, I think Kiara moved Holotalk to better fit her European schedule after Miko.
but yeah, the Holotalk numbers are a good representation of how many kaigainiki fans each Holo has in my opinion. And as we can see in the airing date order, Azki and Roboco (one before and after Suisei) were far behind Suisei in numbers. Hell, after Suisei appeared, only A-chan and Coco got more viewers.
Also Kiara, if you're ego-searching and came over my post, I love how organized you are. I can quickly access your YouTube page and get playlists for every game you've ever touched, and more abstract stuff like drawings, old membership videos you've made available to all and your collabs. As someone who primarily watches VODs this is a huge timesaver, and it made it very easy for me to find the view numbers I just put up. I know a lot of the girls try to maintain playlists, but you truly go the extra mile and then some.
The concert was great, I'd advice anyone to buy the ticket. But I know how the internet works, so if you're not buying it, at least torrent it. Getting to hear Suisei call out the "Please wear a mask, don't record the performance, please don't be a bother to those around you" in her seemingly normal voice was such a treat, and watching her perform on stage seeing her dream get realized was nothing short of euphoric for me.
