(Average+) Cautious Hero: The Hero is Overpowered but Overly Cautious

Series in one sentence:
SIKSH PAHQK.

Series in more sentences:
A young goddess is tasked to summon a competent human to save one of many Earths under attack by high ranking threats. 

Upon seeing him and his stats, she becomes instantly smitten, but soon learns his behaviour is less than appealing. The rude and overly cautious boy is quick to pick up on the rules, though, and the goddess is often reduced to being the third wheel tagging along.

Another RPG world anime, though this one tries to stand out with its assholish main character and good animation. The facial expressions the goddess makes were pretty Western at times, it was fun to see.

The start was good, near the middle it became needlessly perverse, and at the end the entire tone shifts into something that made everything that happened prior feel misplaced. I truly liked the big reveal, that was some good tragedy, but that one episode where they had to fight off a horny goddess was the stupidest shit and then there's this other scene where the main character is "training" while in a lewd position with another goddess. And it's never explained why and how that training even worked. These kind of things make the ending feel like it belonged in a completely different anime. 
I'm on the fence whether or not these rejected hentai scenes were disrespectful to the main character, as the majority of the series does have a heavy focus on comedy..

But needless nudity annoys my prudish brain, and anime has no chill, man. Drawn-out sex jokes bring down the story and waste everyone's time, and it's the reason why I'm giving this show an average+, opposed to a good rating.

I still had fun, mostly.
