Welp here we go again folks. Another new code girl, another overpriced introduction gacha.

I imagine they must've had to pay a pretty penny to be able to directly sell an exclusive unit that is otherwise only available as a code from Japanese merchandise. It would explain why more "Exclusive Code" girls aren't behind released on Nutaku despite there being a dozen already by this point.
I've already given up hope on ever seeing the Nico Premium girls...

The pattern always seems to be to lock the code girls behind an initial paywall before reselling them directly, at a "cheaper" price half a year down the line.
Honestly, they should just sell the character directly the first time. I don't know why they still don't do that. I'd be willing to consider purchasing her directly for 4500 points, especially if there were some slight bonuses in the deal. But they do what they always did to "Exclusive" girls for the first time, put her behind a step-up paywall.

Such a shame. Sasayuki is one of my favorite JPN artists too
