Sepia Tears - easter eggs

Greetings, fellow nerds and Visual Novels lovers!
How were your vacations? Did you play some interesting videogames?
I gave a try to various VNs - and I'll tell you everything about it in the following days.
Today though I want to share with you some funny things I find playing the free Visual Novel "Sepia Tears" on steam.

If you try this bittersweet romantic videogame, you could happen to see some very well known faces...

Does she look familiar?
Well, no surprise........ Even her name suggests an other, famous in VNs world, Rin.
Tosaka Rin from Fate Stay Night!
Well, I admit this pic doesn't do her justice.... XD

But we have another case of unexpected visitors XD

Do you recognize them?
They are Rika from the horror Visual Novel Higurashi.

And Beatrice, from the horror VN Umineko

If you found any other reference in Sepia Tears, let me know!! ^_^
