Greetings from pixiv.
The pixiv Writing Challenge ~ Obsession ~ starts on Monday, November 9th.
This contest accepts novels under a theme that changes periodically.
The theme this time around is "obsession".
Feelings you can't let go of and memories you can't forget. Doting love and jealousy born from loving someone too much, relationships built on mutual dependence, a reunion with someone you still have feelings for. What kind of fate will an "obsession" that takes hold of your heart and refuses to let go bring? Why not tell a story that's uniquely yours?
The winner of the top prize, chosen via lottery among the contestants, will receive a set of useful how-to books on creative writing (5 volumes).
In addition, 10 runner-ups will receive a gift of their choice: an Amazon gift card (1000 JPY value) or pixivcoban (1500 JPY value).
