The story and plot is all over the place. Devil/demon king, gods, Devil fruits suddenly, he got revenge, but it was so too easy.. Its a shitshow, but I'll read it to the end at least.
Yeeah.. that's not cool.
Wonder if its lotto with these summoning's like we do in games (random 1-5 stars), or some criteria the person summoned fulfils to be part of the pool.
Can't blame the goddess to find a new hobby such as this. who knows how long she's been alive for. You would get a little crazy by having nothing to do, and she has to focus a little on him at least since hes got the power to end the world if he wanted to..
Just get rid of her already.. don't give her a redemption arc where she feels "regret" and "just wanted to be loved".. the story is such a mess already and is going absolutely nowhere.
