Danbooru-based image board with a specialization in high-quality images.
For some reason they decided to place these high-res PNG images (for the game package covers and tapestries) in their official site.

Good for us, though :P

why is there no thumbnail?
Fixed one of the char's spelling according to the official site.

Also added the third artist listed in the same site for now until further info released claims otherwise.
Hmm, I must be brain farted for a moment to misspelled her name.
But please don't add 夕凪セシナ in there, this artist had nothing to do with this 4 main heroine.
You can tell that from that from their style, it's not that hard to distinguish them.
