This is my first review so bear with me...
This manga is one of my favorites for so many reasons:

Story - 9
This is one of those stories where at the end, you feel immensely satisfied, but sad that it didn't go on forever.
Unlike some stories of the time-travelling genre, this is pretty realistic as far as fantasy goes. When Noriko first arrives in a strange world, she doesn't understand the language there, which is pretty rare in other stories of this type. She has to put forth some effort to get along in her new world. And she has a realistic yet optimistic view of things; she's not some happy-go-lucky, tra-la-la ditz like other shojo heroines. She's tough, I like that in my heroines! And Izark... he's so handsome and so loveable! You feel sorry for him because of his "fate" but at the same time, he's such a nice guy and he always puts on a brave face, so you find yourself cheering for him. Not to mention he's one heck of a warrior!

Art - 9
The art is simple and beautiful. It's an older manga, so for those of you who mostly read mangas with the newer-style art, the drawings in Kanata Kara might take some getting used to. Personally, I think this is some of the best artwork in an "older" manga that I've seen, and the body proportions are good.

Character - 8
The development is smooth and pleasant. The way things progress, it all feels so natural. Only once or twice during a few chapters did I ever feel like the story was dragging a little, but it always picked up the pace again in the next chapter or so. If I had to choose, I would prefer a story to lag a little than to rush things too quickly.

Enjoyment - 10
There's a reason this story is one of my favorites. I enjoyed reading this manga, and it doesn't leave an overly-sweet aftertaste either, unlike a lot of stories in the shojo genre.

Overall - 9
This manga is really a classic. I think almost anyone who reads this will find themselves laughing & crying with the characters.
