Story(5/10): story is pretty simple really... its about a guy who doesn't have many friends. you can read it in the synopsis in MAL so im not gonna talk about it.
Art(9/10): possibly the strongest point in the anime.. it is really good to look at. no problems with it whatsoever.
Sound(8/10): I didn't really like the OP and ED but they were acceptable. voice acting is pretty solid too no problem there.
Character(3/10): now okay this is where things go wrong in this anime... the characters are so bad and there is no development whatsoever except for like yozora and sena. you have a pretty decent MC no problem there... Yozora is a total bitch but she plays that role perfectly so no problems there either.. Sena is kinda air-headed but she's cool too. But lets come towards his little sister.. okay i get she's a weeb and likes to cosplay.. but come on... every time you show her is it really necessary that she has to be in that role? she has no character imo. Also the nun is pretty good but her poop "jokes" aren't funny. Also there is a weird dude or a lady idk what the hell it is i cant remember. the perverted scientist rika uses too much overused jokes and in the end she is a nuisance instead of being funny.
Enjoyment(5/10): the comedy is terribly placed and therefore it is kinda hard to really enjoy this anime.
well I wouldn't say it was a complete waste of time.. but it was a waste of time
