Thanks for the chapter!
So she's ultra powerful but restrained due to his low stats. While selfish she seems nice for an ultimate class demon. Likely will eat him into extreme debt with a black hole for a stomach that'll never be satisfied. Personally I'm a little tired of seeing ultimate demons portrayed as loli-babas. Would be nice if she matures physically (and mentally as she acts like a teenager) as MC gets stronger. In any case, she seems to have taken a liking to him and she's just what MC needs to get that push to get stronger. Hopefully he'll maintain his ideals of what an adventurer should be without developing scummy habits like his former party, albeit tempered with wisdom so doesn't charge towards a heroic death stupidly.
