Tsuina-chan suspiciously keeps tweeting about Synth V
Someone tweeted about wondering why Tsuina greeted Aoi and Akane to Synth V ("for research?"), commented that Rikka is also on Synth V and that Synth V is on their mind.
Tsuina quoted it and laughed evilly ("ufuffu, is that so?...
) and goes on to elaborate, for reasons that definitely aren't suspicious, that Synth V also works on Mac and that is a very nice selling point.
AHS is having a booth called Voice Connect where they will be selling Voiceroid goods. I'm not really sure what she means, but she mentions stuff also being sold at a Synth V event.
I could see Tsuina crowdfunding a singing voice. And I would be in line to buy it, haha.
