The story was wonderful, the art was fantastic, everything was absolutely amazing.. up until the end.
The ending was an absolute let down. It couldn't have been worse. I felt like I had read the entire manga series for absolutely nothing. I love the rest of the story and the characters, but ending it all by ( MAJOR SPOILER ALERT ) having them erase Karin's memories so she didn't even remember her family?! What a cruel and stupid way to end a manga. The person who wrote it obviously didn't have enough of an imagination to find a better and more satisfying way to end a manga. I am extremely disapointed.
My suggestion? Don't even bother reading it.
