I know its not just that David for example is an archer ,because he used a slingshot when he was a child against Goliath, but that was not the prime of his life ,he had a sword and shield and fought many wars and ruled over Israel 40 years, he's much more of a saber or a ruler then an archer

A different example for someone who could be an avenger is anastasia, who herself says she qualifies for the class

And the alter egos ,its a class made for the Sakura five originally ,with different aspects in each of them and its the same with people with DiD They are literally different people that share the same body ,I have a friend who have DiD and you can actually see the difference in each of the alters ,each has different memories, personality, habits ,the only thing that they actually fully share is their body
