Didn't actually watch the first season until a couple of weeks ago. But disregarding the cliched echi gags I found this anime to be quite original in some ways and it really got me hooked. Most of the characters were interesting and it's a first in a long time that there's an actual male protagonist who's not afraid to punch a girl in the face. I'm glad too see the second season is following the same pattern, a bit more gags though, but nothing that will put me off from watching it. I have no complaints here at least.

This one was also quite original in the start, the protagonist is an actual normal guy. No quirks, not weird fetishes, just a normal guy who has a normal "sister" relationship. They fight, they don't let each other go into their rooms and so on... Now the thing about his sister being a secret otaku was funny, and still is. But I honestly don't like the direction the anime is going with the incest insinuation. Even if it doesn't happen and there's a twist, it feels like the creators are just trying to play on that gimmick and shove it down the viewers throat. (Not to mention I hate it when normal characters solves situation with completely irrational and out of character solutions)

I honestly still don't know what to think of this anime. Is it original... not really... It's fun and cheesy. Echi jokes are a bit overused but somewhat effective. I do like the art style though, pretty original, and the action is pretty cool as well.

I honestly didn't know this was the second season of something so when I started watching it I was utterly confused. When I realized I went back to the original season (still watching it), so no comments on this for now.

I like it, it's cute, charming has a decent story and some interesting hooks and plot direction. It's still at the start and not much plot development has happened since they're still introducing the individual characters.

Too cute... the whole scenario, protagonist and story just melts my heart for some reason. Maybe it's because I'm a geek as well, but all I know is I'm in love (lame I know xD). And the intro... so good.

Watched the first 3 episodes, couldn't watch anymore. This is just my opinion but it's bad... Nothing about this is funny, original or heartwarming. It's just forcing girl on boy violence gags to the max.

My first impression of this was: "What the hell is this crap". But then I thought about it for a while and continued to watch it. I then realized it was the perfect parody, cutesy childish animation/art style with extremely adult themes. And lately there has been some really good action (Episode 6 to be specific). It's fast paced and some of the stories are extremely funny and interesting. Downside is, it's a parody so it's bound to have some bad or unfunny jokes or episodes. But all in all I would have to say this is borderline genius.
