Change 123 is a story about a girl named Motoko Gettou how suffers from DID or Dissociative identity disorder in short Multiple personality. Motoko has a hard time living her life as the other personalities try to live there will protecting her from harm. She soon meets a befriends Teruharu "Hideo" Kosukegawa how is a bit of a perv but very kind and soon helps her with her multiple personalities. So the stories is about living a normal life while having a unique mental disorder. I really liked the flow of the story from the start to the middle but the ending really sucks.
Good Points
1. Comedy is very good (specially the snake bite ^^)
2. As a martial arts genre kind of manga its very nice like Baki
3. Ecchi there are nice ecchi scenes in the manga not to point of hentai kind but very nicely time moments.
Bad points
1. The Ending had little to tell about the whole story. It just left with little answer.
2. Characters had little growth in the story or should had more influence like:
Motoko's grandmother, should more more story about her family in her mother side. More depth on Motoko's mother. And Zero. Zero is the problem the dark personality in the story, but in the end she was nothing. (I want to explain it more but I cant because of the story it self is like that)
Overall I give this a 5 I'm very disappointed about the ending because I'm a fan of the series and well just read my "PERSONAL" thoughts about it below.
"MY PERSONAL THOUGHTS"
It was really good but what the hell... what kind of ending is that!!! totally creepy, like having your old girlfriend become your own daughter... I know I'm being one side but I expected more from this and a longer better story, not a rush shit ending. This sucks and I just finished the last chapter and I'm really disappointed.
