Oriya ???? is it the name of the author.... Oriya is actually a regional language of India...

Also Oriya might be a way to spell a Russian name Olya in a Japanese manner.
Just like Origa (originated from Olga). Actually Olga and Olya are the same name with Olya being a pet name. I heard that the manga has started as a piece of original fanfiction wrote by Oriya around 2012 which evolved in manga in 2015. So my guess is that Paperheans is the illustrator here. Kind of exciting. (.
