This manga was good up until this point, but the ending of this chapter went completely downhill. The author is really forcing a situation of continued battle a little too much. MC should have just killed Avel when he had the chance. And why in the world would Katua be protecting him when he hit her and tried to violate her? This is just too forced.
And the MC also went to far with his stupidity at the start of the chapter. Why the hell would he intentionally provoke the Goddess when he could have just refused normally? I get that he is super pissed off by her but that does not mean you should anger a divine being with power greater than you could even imagine.
