W: Wish

It's an ok-looking series with a neat premise. It's not that any of it is totally original, but it's done pretty well considering how short the series is, not to mention the short duration of each episode. I particularly like the opening theme. Not even in the top 10 in terms of my fav anime music, but it's worth at least one listen, even so.

I had a good part of the story figured out half way through, but there were some elements that caught me by surprise, so I wouldn't say it's totally predictable. The series could really use a re-writing and expansion, much like ... was done with Kanon with the remake Kanon (2006). There's some neat (albeit cliche) secondary characters that could have really been given some depth. As it is, only Junna, Senna, and Haruhi get any notable development. Even that's pretty shallow.

I guess the thing that really puts me off on my ability to really enjoy the story was the borderline-incestuous relationship between Junna and Senna. I understand the Japanese culture views siblings a bit differently than Americans do, but this was going a bit far, in my opinion. I'm just thankful this doesn't even get ecchi. I'd have had to stop watching otherwise. The final unfolding of the story makes everything a bit more clear, but it's still a bit disturbing. Perhaps I'm just not used to this kind of story, but still...there's a line...

Despite cringing at every cry of "Onii-chan!!!", I still managed to finish it. Again, I liked the story and think it's a great baseline for a good plot, but it needed more fleshing out and less "special sibling bonding". My advice: just try to follow the story and ignore the suggestiveness involved. Not easy, but it can be done.

Overall, it was okay. But don't let the genre tags fool you.
First of all, it's not a romance. Unless you think of an overly clingy little sister as romantic, I guess. There are no romantic feelings involved in neither side whatsoever.
Also, I wouldn't really consider it Harem. There are 2 girls clinging to him, which both are in some way (it's complicated) his sisters. That'd be a pretty small harem in my opinion.

So, if you want to watch this because you're looking for a harem/romance, you most likely won't be satisfied.

Considering the short duration of the show, the story was fine. As it also ... includes a supernatural aspect, some things are left unclear or simply have to be accepted 'as is' for it to work out. It's rather predictable, nothing mindblowing.
