Entropy's Servant

"I see. If someone's wronged me, it's fine if I just take revenge, right?"

After having presumably died, Arthur is reincarnated into a 'fantasy', almost game-like world by its Goddess of Light with only a few memories on set subjects, and, grateful for this second chance, he decides to try to help this world as well as he can.
However, after a 'certain event', it turns out everything isn't as nice as it seems, and...?!
Now serving the Goddess of Darkness and determined to get revenge and win his adorable goddess's heart in the process, what will the man who has taken control of the Monster army do?

(Updates on Tuesdays, 19:00 GMT.
If you live somewhere else... figure it out~?)
(The cover is a WIP, technically. Still working on the full version~)
