I created a pool for this and uploaded the two pages from his pixiv page. I'm guessing SC50 is a reference to some sort of comic event where this will likely be sold in the future? If so, it'd be nice if it could get uploaded and added to the pool here.

Until then, enjoy the few pages we do have.

SC50 is Sunshine Creation 50. And yes, it is a comic event. It's still upcoming though, so you'll have to wait a little.
