The stories not that bad, I just think the main character is annoying, and the story doesn't make sense at time. Can't really give a reason why I think that, but that's my impression. Here's an example of the story not making sense, how is a bunny of all things going to fight other monsters with sticks, when he doesn't have thumbs. I know he's a former Demon King, but that doesn't change biology. He's a bunny.
