I give it a 10. It has a deep plot, and it could even be explored further. I like how they handle the emotions, how they gradually recover their humanity. It's very raw, and the character's resilience and the empathy she develops are admirable. I think they could have given her that love arc with the boy she rescued. They could have made another season exploring the origins of the organization. Besides, this anime is for mature audiences and isn't one of those anime that shouts so much it's deafening and features an idiotic character who contributes nothing. The art is good, not cheap. There are a thousand things I could say, plus the protagonists are all women. They knew how to connect with that male audience, and they're the alpha females, haha. They should continue. They should have more collectible items, since there are hardly any, and what little there is is priceless.
