Answer:
Improved 1/30/11: No. Your all wrong. Maka is 14. Soul is 15. Liz is 16. Patty 15. Kid is 14. Tsubaki is 14 and Black star is 13. In the manga they are 15-17 now. But in the anime, they all range from 13-16. I did my digging and it's true. This person wants answers not guesses...
Please post the chapter where you supposedly found that information.
The only thing ever stated about Maka´s age was in Chapter 75,where Giriko refers to her as a 14/15 year old.
Where exactly is it said that Soul is any older than Maka?Be it anime or manga wise,I`m almost perfectly sure no one stated this.
