In Season 3B, Kira's mom says she has aprox 900 years old (event that occurs in 2013) with her face looking like a normal person in her 40s but in 1943 she is way younger (Kira's age) and according to her age from 2013 (900) she must have sth like 830 back in 1943... If it took her 830 years to look like Kira (highschool girl , 17 years) then why 70 years later her body aged terribly looking in a normal person's 40s?

@SuperSaiyanLabRats I just finished Season 3BB (minutes earlier) and I can easily answer your question. The earlier waves of Oni were weaker than their succesors, Kira's mom explained that some of her tails are stronger than the others and the fact that Scott was an Alpha also helped. Keep in mind that the last wave of Oni (the ones who killed Ethan) also poisoned their enemies with their swords, the earlier waves couldn't have done that (Agent McCall's case)
