Saikin, Imouto no Yousu ga Chotto Okashiinda ga. follows a family just starting to rebuild. When they marry, Mr. and Mrs. Kanzaki bring a teenage son and daughter along for the ride. But high school freshman Mitsuki Kanzaki is less than thrilled. Stinging from a history of absent and abusive father figures, she is slow to accept her stepfather and stepbrother.

But after an accident lands Mitsuki in the hospital, she finds herself possessed by the ghost of Hiyori Kotobuki, a girl her age who was deeply in love with Mitsuki's stepbrother Yuuya. Hiyori cannot pass on to her final reward because of her unrequited love for Yuuya, meaning she's got to consummate it... in Mitsuki's body?!

Now, Mitsuki's life depends on getting Hiyori to Heaven. But will she get used to sharing herself with a pushy, amorous ghost? Can she overcome her distrust of her new family? Can she bring herself to fulfill Hiyori's feelings for Yuuya? And might she be hiding some feelings of her own?


The anime was streamed by Crunchyroll during its airing. The source material has also spawned a live-action film and a light novel series.

This anime, unlike many other ecchi anime, has a story line that is not difficult to follow. Although, people seem to complain about not knowing the answers to questions, although they are right in front of them. For example, if you would simply watch the ending theme all the way through, you would learn all you need to know about Hiyori's past.

The art was not hard to look at, but some scenes were just a little off in appearance and the way characters bodies were drawn.

The voices were easy to listen to and matched the characters very well. I especially enjoyed the difference in Mitsuki's ...

Mixed Feelings
Saikin, Imouto no Yousu ga Chotto Okashiinda ga (or the shorter English title "Recently, My Sister is Unusual") follows the story of a young girl and an older boy who become step-siblings due to their parents marrying each other. The setup is pretty standard, but the catch is that the younger stepsister gets possessed by a ghost who's in love with the older brother, is forced to make moves on the brother to send her new poltergeist companion to the next life, and ends up falling in love with him in the process. Mysterious missing parents and ecchi, incesty hijinks involving a chastity belt then ...

"Recently, My Younger Sister Is a Little Strange" is what you get when people try too hard to make an ecchi show. First of all, why would you even make a show revolving around a high school girl wearing a chastity belt if the chastity belt has to be blatantly censored almost every time?

This is one of those shows that you know is going to be horrible right from the premise. An extremely generic and oblivious guy, Yuuya, gets a new sister, Mitsuki, after his father remarries. Mitsuki soon runs into a ghost, Hiyori, who has amnesia and can only remember that she loves Yuuya. ...
