because the मांगा always comes first and the ऐनीमे never goes completly द्वारा the मांगा so the मांगा is the real story like take Shaman King for example...*SPOiLERS* in the manga, in the end Hao becomes shaman king and DOESNT die but in the ऐनीमे when Hao becomes shaman king he gets killed AND Matemune is in the मांगा but not in the ऐनीमे :p
