You see, everyone else gives fan service from times to times, but never Ina. This maintains her pristine illusion of a "Yamato nadeshiko".
Takos have been starved are craving for content like this. So it really feels like magic for them. The others? There's already VODs for that.
And about the figurines, while Gura is at the top of the pack, there might be a reason for that: Gura is now as commercialized as Mickey Mouse, and can also be brought by normies to show off that they know 'vtuber' culture (not to mention she's this gen's zoomers' Barbie). In retrospect, the Takos seek more than the flesh (nendo)---but human connection---which Ina has deprived of them from, like Kaguya princess from the Moon.
Sadly, Ina will never truly be the Takos', and Takos know this much, and they are OK with this because they had been putting her on a pedestal for the longest time, and if Ina were to submit as easily---it would have shattered the illusion that she's a pure maiden---thus this makes the Takos the biggest cucks of all, and the proudest of them all. Like simping for some royal princess they know they will never reach.
