>>14771673They're not bringing on Ina to advertise to Hatsune Miku fans, they have the Hatsune Miku aspect for that. They are bringing in Ina to advertise to the Ina fans. Didn't think I would have to explain something so obvious. There's a chance someone doesn't care about Miku but buys because of the artist, or they like both Hatsune Miku and Ina but don't normally buy and the collaboration aspect put it over the top. These are the very obvious outcomes they are hoping for, or the third more rare less controllable one of just buying cause you like the design. If you have any other questions, such as how to wipe your own ass, or even how to find it since you seem that slow, just ask.
