When the MC dies he chooses reincarnation and is gifted with an ability or an artifact. Due to the goddess' haughty attitude he chooses her instead thus our problems began. The goddess is that of an op arch priest with terrible luck and acts like a spoiled 10 yrold. (Of all the character in the story she's the one I dislike most.) The only way she can return to heaven is to defeat the demon king with the protagonist. (Also the MC can return to his world after defeating the demon king). At first I'm find with her but she still doesnt change after 6 volumes gets on your nerves a little. I don't mind he's getting dragged into problems but the author could do a better job initiating the conflict.
Fighting orcs when they are out number and outmatched but still manage to barely win?
