The characters are bland, dry, and given a singular defining characteristic each. With the exception of best girl Rui, none of the characters show much development at all. The series is very disjointed and they feel more like general ideas of functioning human beings than fully fleshed out characters.
The series starts with two teens getting it on in the name of science. I mean, what better reason to lose your V card than simply because you want to understand what it means to have sex? Sudden plot twist shows that the two horny teens are now siblings! What a twiiiiist.
As it progresses you get to meet the rest of the wannabe harem: a hot sister sensei, a bodacious babe with a tendency to flock towards any male willing to give her the slightest bit of attention, and a shy green haired cutie that really doesn't want to be lumped into this harem. Don't get too excited now, only two of the girls really enter the picture beyond a mere mention of their existence.
The younger sibling, which I already introduced to you as Rui, is a socially awkward blue haired beauty that really just wants to feel literally anything. She is like a robot in a flesh suit just yearning to feel any tingles of those pesky little things called emotions.
The older sibling, who was the main protagonists love interest and teacher long before becoming siblings, is a drunken mess of a human being that is currently partaking in an affair with her *gasp* old high school teacher! Anyone detecting a bit of foreshadowing here?
Pick your ship now: big sister or little sister? If you said big sister you are garbage and cannot sit with us. Anywho, the love triangle follows the three now siblings in the ups and downs of what it means to be a horny young adult with no sense of self control. The whole being siblings thing could really be played up more as it kind of falls into the background which is sad because I am a garbage human being that wanted some more incestual mockery to occur. How in the world did the parents not notice any of the steamy sibling on sibling action going on around them? I guess they too were probably too busy boning to give a shit about the real world.
Our horny protagonist gets the best of both worlds for the better part of the series until the older sibling realizes that he has legit feelings and not just puppy love and the younger sibling has one of those "whoa, what is this feeling? Is this a feeling?" moments and realizes that she may actually like this empty shell of a plot device. There is the usual will they or won't they back and forth in the relationships as the series attempts to give you emotional whiplash but all in all it falls together rather nicely.
So what reason do I have to rate it as good instead of it being rated as the total mess that I clearly reviewed it to be? Well, the answer is pretty simple really. I am trash and the show gave me the feels.
It is not handled the best and the characters could really use a personality dialysis but the story line (what little there is) is pretty decent and by the end I found myself audibly rooting for my sister of choice, much to the dismay of my partner who did not wish to be inflicted to this trashy soap opera of an anime. The art is really pretty to look at, the music is decent, the opening theme is fire, and the way the first season ended was exactly what I had secretly been hoping for. I love when unrealistic happy endings are ripped away from the cold hard hands of the fans.
Look, this series is not great. It is probably pretty bad to a loooooot of people. If you like soap operas, trash television, hentai plot without any actual sex, not like we are blood related sibling love, or just making yourself suffer than you may actually enjoy this series and should give it a shot just for the fun of it.
