Let's be frank
3y on, the Vesper x Kronii collab still casts a huge shadow over what people expect from a Holo x Star collab.
That collab was funny, bar none, and earned the Stars a lot of good will.
And the worst thing is, people really hold it up not just as the Gold stard BUT ALSO what they think MIGHT happen if their fav girls and boys collab with each other.
I watched a few of those Shiori x Homo collabs. They are boring as hell. Same for the ones with Liz.
But beggars will keep pushing for more because they still hoping to struck gold again.
