This paper toy is A-Ya, the main protagonist of the Shuuen no Shiori Project, designed by (se)renna, using Nasos' Graphig Template. A-ya is a rather unsocial student with the unusual hobby to start rumors for his own amusement, where he does not consider the feelings of the affected person.
The purpose behind this is giving his usually boring life an exciting twist, as he greatly dislikes his life as it currently is and seeks for the thrill of fear and comedy, caused by a person's personal drama. A-ya has red eyes and black hair with an ahoge on the top of his head. He is shorter than C-ta.
