I really enjoyed this story! Sure there are some character flaws here and there, but most of them get explained in the last volume. At first, I thought the storyline was kinda hard to follow, especially cause I'm not native in English. However, the curiosity to find out where the main character's sister had gone, kept me from putting it down. So when I finally picked up the last volume, it was safe to say, I wasn't disappointed! I can't tell you exactly why, as this would be a major spoiler. I have read my fair share of manga and I'll have to say thatthis is definitely my favorite series so far! It's been almost a year since I read it, but I still find my mind drifting towards it sometimes. If you are looking for a quick series to read, I definitely recommend this one!
