It's been a while since I've read it as it was my second manga ever read which has been almost 10 years ago or something like that. But what I remember is fantastic characters and their development.
Alita herself is my favourite character. Her pure strength and will power that keeps her going to find herself and help others around her is just amazing. Her journey is a interesting one in a cyber punk world with people fighting for survival.
The way this manga is drawn it's totally breathtaking. I wish I could draw like that haha. I can't only drool over my thoughts of it in colour.
This manga has a movie adaption but it really doesn't do the manga justice as it's kinda short and doesn't bring out the true awesomeness of the manga. But imo it's still a good watch.
Seriously read this manga if you love the cyber punk style. Hell even read this if you don't like it. It's a fantastic story and will be appreciated by all who read.
