Agree, like I always was curious if I got a chance to see Daim Yokai female descedants in Inuyasha(when I watched it first time)...and she actually lived up to expectations.
I couldn't call her evil either, case she wasn't enjoying by killing humans, she just did it to save her mom. And she was strong, I loved her hybrid form tho, like we saw her mom and what her form exactly is, but Abi used half-human and half-bird form, with that fire attack. I feel like she was really strong, but hmm wasn't possesed with power idea, that is why she lose to Naraku.
And yes, I hate how her life ends...she could be intetesting chatacter. But it is what it is...
Still, maybe we get more Daim Yokai in yashahime, so there is still hope...
Kagura was weaker than Abi, from my point...
Like yes she has that wind attack, but Abi is Daim Yokai who could turn into full bird form, and that could be damaged only by something like Tessaiga.
If we talk about characters, Kagura and Abi are absolutely different girls, so it's not easy to say who is better.
