Dammit, I haven't read a story that actually made me a little teary eyed in awhile.
I adore this story. I can't help but wish that we had more of it or got an Anime adaptation.
~~ Spoilers~~
(I'm really bad at remembering Japanese names)
Things like one of the MC's having a feeling of abandonment from her parents and feeling like she was always in the way of her parents who mostly payed attention to her little sister, It's really interesting and the way the story portray's it makes it believable. I'v seen other stories try the same thing but just comes across as whinny and annoying. I do wish we got more of the MC feeling resentful against her parents. They could've easily expanded on this much more.
I like that they actually did stuff with the Sister being an Angle and wasn't just for one off jokes.
Near the end when it fully starts dawning on you that the Little Sister is an actual Angel. It honestly made me start getting worried that she was actually dead. If the story ended with her actually being dead then i probably would be such a fan of this story.
I even like characters like Oga ( Even though i was already thinking she was probably a girl from the start and wasn't surprised at the reveal ) and how she doesn't come across as annoying and has a nice relationship with a high school girl that first mistakes her as a boy. I wish we got more of Oga starting to become more girly.
I wish we got more time of both the sisters in the hospital. Such as have the little sister estimated life that she has to be something like a couple days and the sister finally willingly gives her a kiss not as a sister but a lover, It's then that the Little sister wakes up.
Really if i had to say one thing that i found to be a bad part it's the final conclusion. With the little sister waking up from the coma but not remembering anything that happened. Or at least it seems that's what happened.
Overall this is up there with one of my favorite manga's. I just wish we got much more then this.
