Why is every new Yuri so edgy? That's fine if that's what you're into, but there's been such a drought of nice wholesome romances. I guess the arts pretty good though.
I'm not sure where this drought you're talking about comes from, I couldn't tell there was such a drought in the first place.
This is an interesting start, I like that the blackmail bit was turned on Serina. I was expecting other things from the tag, so it's a nice surprise to see that Reiko's got more bite than bark.
