Unfortunately, Rokujouma is one of them.
Initially, this is just your normal haremish anime which just uses the grand old concept of girls moving suddenly into your room, with a good comic setting. Nothing wrong with that. And they play games in order to decide the room allotments. Nothing wrong with that. But when they suddenly change the narrative from playing games to something else, like I don't know, supernatural interference, then you suddenly contort the characters in such a way that you don't know them anymore. That's when it goes to shit.
To start with, the initial few episodes were laudable and funny in their own way. Everything looked like we will experience a slice of life with nothing to worry about. Then suddenly one of the girls starts to develop a problem with the hero during a beach episode. Then another girl develops a problem, then another. The cycle continues. And it all ends in the same way: The so called normal hero suddenly being able to absorb infinite energies that he shouldn't have been able to, along with the all the other girls just teaming up and destroying the enemy. EVERY TIME. What is this? The gender-swapped Avengers?????
At one point, this grows really annoying, so much that at a time when one of the girls has to face her enemy fair and square, when the suspense is built up fairly, and when the interesting element comes within, the hero just rushes in to save her and determines by some writ law, that they will all gang up on the enemy and destroy her, even when the enemy was actually the one who arranged a magically isolated location so that no one else would get hurt and she would get to test her skills well. And said hero doesn't even trust the girl's claims at all, just because of a selfish desire to preserve his inferiority complex.
I am getting ahead of myself in this part, but long story short, don't watch this anime if you think that you liked the first few episodes. Cause then you will definitely hate the last few. This is that kind of anime.
