Why do I say this? Well, it's quite simple. Most harem anime seem to be similar in story line because they know that their target audience would probably care more about the girls and ecchi than a compelling story or whatever.
NouCome took an interesting approach by wrapping a story around the consequences of CHOICES. This is instantly evident by the first episode.
Where most harem anime would rely on accidents or sticky situations to initiate ecchi scenes, this anime straight up yells "CHOOSE!" and makes the MC directly enter that situation out of his own will. I can see how that was a relief for the writers. That being said, NouCome has just enough ecchi scenes to BARELY qualify as a ecchi genre anime IMO.
Of course, innovative concept aside, that alone isn't enough. Fortunately, the MC also differentiates himself from the normal tropes of a harem. The only thing that makes him more interesting that any other harem MC is his sense of humour and the literal choices he is forced to make.
These two concepts combine to create an absolutely HILARIOUS anime. Almost every episode is filled with meta jokes, an ungodly amount of references, and overall just a side splitting experience. The MC alone is the most funniest character in this anime on his own. There are moments where you do feel bad for him, but most of the time, it does lead to some amazing comedy scenes.
The humour alone is enough to save this anime in my opinion from it's flaws.
Despite it's many unique offerings, it wasn't able to save itself from what I consider to be the biggest flaw, which is underdeveloped characters.
Almost all the characters in this anime, including the MC, don't evolve overtime and in the case of the female cast, remain adhered to their stereotypes till the end of the season. There were multiple character developments that the anime was smart enough to feature, but never bothers exploring further at all. But then again, this IS a 10 ep comedy after all so it would be harsh to expect too much of this. That being said, a little character development never hurts.
Absolutely do not expect a decent story out of this anime as is the case with most harem anime. The overall story, while being wafer thin, ends with a very underwhelming ending. Much like the characters, there are a LOT of questions about the mechanisms of the MC's affliction that almost never get answered.
Overall, it's absolutely amazing that they even TRIED to be different. That gets points in my book. It's almost tiring to see the same tropes recycled over and over again even if I'm mostly there to beat the shit out of my dick to. NouCome's uniqueness outshines it's commonly seen flaws. It's therefore, much easier to just enjoy the amazing comedy and tasteful ecchi while laughing along with God at the MC's plight.
ABSOLUTELY recommend it. Go ahead and give it a watch.
