Anime First Impressions: Recently, My Sister Is Unusual

Today I'm going to be reviewing what is very likely smut.  There's no other way to describe what I'm talking about.  The show I'm referring to is Recently, My Sister Is Unusual.  The show is about some guy likely in high school who discovers that his step sister suddenly started acting weird.  Weird, as in, like she's possessed by something and also is coming on to him.  Romantically and quite possibly sexually.

Basically, this is probably softcore porn featuring technically-not-incest.  And I already know for a fact that this is going to be messed up.  My only question is how messed up does it get, and how comedic of a spin does it take.  It's possible that this may actually be entertaining, but my hopes are definitely not high for this.  Currently, the show has a 2.6 star rating on Crunchyroll, and when you consider that every show on Crunchyroll is incredibly inflated, that score is probably closer to a 1.6 rating.  Also, confirmation that it's smut comes from a friendly warning:

Yeah, this is going to be incredibly perverted.  Crunchyroll does not give 18+ warnings lightly.  I am going to regret this.

Recently, My Sister is Unusual - Episode 1
0:00  Looks like a normal day in Japan.
0:15  Our main character wakes up to the sound of an alarm clock.
0:30  One day, he woke up and found that he had a younger sister.
1:00  Breakfast with the whole family, something every family should do.
1:30  Apparently, the father is flying to India soon.
2:04  It seems that the two kids are still strangers to each other, and each other's respective parent.
2:35  That was an awkward goodbye.
2:45  And now our main character is talking with a friend about this whole thing.
3:10  His friend has a serious fetish for little sisters, which is apparently culturally acceptable in Japan, and is surprised he hasn't slept with her yet.  Hint: DITCH THE FRIEND.  HE'S A TOTAL PERVERT.
3:50  Our hero looks out the window during his class to see that his new sister is terrible at athletics, but she is making friends.
4:05  And naturally the teacher is talking about marriage between siblings and how that used to be common.  Okay, maybe this is a cultural thing with Japan.  Or maybe this show is just bullshitting.
4:30  Another incredibly awkward conversation between brother and sister.
5:00  After trying just about every honorific, he finally gets her attention.
5:15  Okay, why did she just fall backwards off the stairs?
5:35  Well, she's dead.  That was a great show!
[Actually, this is where the fun all starts. And by fun, I mean smut.]
5:55  Darn it she only fainted.
6:04  Well no wonder she starts coming on to him later!  He's staring at her as she sleeps, and we all know how girls find that to be irresistably sexy.
6:30  Seems that she doesn't remember what
6:33  Damn, that heartbeat was so loud it knocked a painting off the wall in the next room over.
7:02  Oh no, here it all starts.  She just grabbed onto his coat after spending the last 30 seconds panting.
7:12  Wow, the most stereotypical porno music just started playing.  And now she's rubbing her hands across his back while in a hug, talking about how much she's always loved-
7:29 "DON'T TOUCH ME" she says as she kicks him out of the room and almost knocks down a doctor who was walking by.
7:39  Gee, I wonder what gave you that idea.  Though to be fair, that's the exact thing you tell a doctor after such a circumstance.
7:42  Finally, the opening theme.  It's exactly the kind of thing to expect.  A sickeningly sweet j-pop song.
9:16  Good it's over, and now it's sunset.
9:36  So, the mother is driving her home, and apparently she's about to run off as well.  What a setup to a wacky romantic comedy about technically-not-incest!  To be fair, Oreimo is also a wacky romantic comedy about incest, but it's a good comedic show which uses the incest as a subtext for social commentary.
9:55  And immediately she runs into her room.
10:40  She overhears the two talking about how they're going to both be leaving the house for a bit.
10:45  "Why did I do that?"  GOOD QUESTION!  So, apparently she also thinks that she was possessed or something.
11:15  WTF.
11:30  So, the reason she fell off the stairs is because some girl in a pink dress with angel wings suddenly appears, said she needed her to disappear, and flew into her.  I'm pretty sure that would cause anyone to fall off a flight of stairs.
12:00  So she wakes up to discover she's wearing bondage gear underneith her skirt.  She suddenly starts panicking.
12:05  Thank you censorship.  And I say that with no sarcasm whatsoever.
12:11  Hello magic floating pink dress angel girl.  Oh, she's a ghost.
12:20  I think screaming is the only right thing to do in this scenario.
12:40  And the ghost starts raping her or something.
12:55  Oh, the ghost was merely stealing her body.  But did they really have to animate it so that it looked bad?
13:20  Okay, yeah, smut 100% confirmed.  The first thing the ghost does now that she has a real body is masturbate.  Thank you censorship, but seriously?!

Okay, yeah, this is smut, just like I feared.  I'm done.  Such a shame too, because the rest of the show looks like it could have been good.  There's decent humor, the plot summaries I've read sound insane in a good way, and if not for the outright smut this would be an entertaining show.  Unfortunately, it crosses the line in my opinion, so I can not recommend it.
