This is a beautifully crafted, well-made, adorable, posable figurine of Tsukasa. Her exchangeable parts are easy to manipulate, and posing her is easy. Her stand is sturdy and she's simple to secure. I like that her skirt is flexible, and I like the example poses on the box, which are pretty easy to replicate.
I have two complaints. The first is that her bendable parts (i.e., her limbs) are made somewhat unsightly because of the clearly visible hinges. They may be necessary to make her posable, but it still might bug some. It's a drawback, but it's not bad enough to take away a whole star. The other problem is that the exchangeable head of Hiyori is not compatible with the stand. Her hair gets in the way and there is no hole to fit with the securing peg, so posing her upright is impossible. But if you just care about Tsukasa, it's not a problem.
Although she has a couple of unfortunate drawbacks, she's cute enough to make up for it. If you're interested in this to begin with, I think you'll be satisfied when you get to play around with her.
EDIT: A comment to this review told me that you can, in fact, pose Hiyori. Part of her hair can be removed to reveal the peg-shaped hole, allowing her to be posed. Very cool. Thank you, Kari. :)
