@Joey102 Not the Goddess, but when he figured out who the Heroine is. Going by his reaction she's the one that kicked the shit out him the first time, and they both forgot about each other until now. She probably committed suicide after beating him since there was nothing left for her to do, came to our world, committed suicide again, came back to the original world, and the Goddess gave her immortality so she couldn't leave again.
Now, this manga could go into two directions. Stick with the gag manga style and they try more creative ways to kill the heroine, or do the logical thing and go after the goddess that did this to her.
@Tamerlane Dishonored dwarf literally too angry to die. Outlives his own gods. So awesome that his presence causes even bards to become iron-willed sword swinging heroes.
The corruption plan was the most promising so far, I mean if she became evil and went against the world - her goddess would have been forced to go against her so her blessing wouldn't have mattered
