No buddy, the sacrifices that I talking about is when Michiru-chan sacrifices her life to revive Nana from dying. And killed the twin girl? Well you know.. Tsuruoka is dirty sly human who forced Nana to kill Koharu-chan. She remembered about Moe-chan grandmothers that said please don't let her astray, so she killed Koharu-chan unintentionally. She didn't want Moe-chan dirty her hands.
That's because Hinata never really had any attachments towards others except for her original family and Sasae loves his current family so when he saw that Hinata finally made a friend and is happy with her he just can't bring himself to hurt her.
Got one. Sacrifices? What sacrifices. If your talking about the people she killed that's not a sacrifice. That's plain murder. Well she didn't break free, she killed the twin girl even though she wanted to run away and redeem herself and she can't redeem herself no matter how hard she tries. Sure she found out that talented people deserve to live but she still almost killed one and did kill one. She killed the one who knew her identity.
the art is good too, it captures the atmosphere of every scene correctly. the story is decent, but it does portray the society in real life if not exaggerated. the drama / tragedy keeps you on edge. overall, its an easy 4 out of 5 star by the almighty me.
And yes for justice for all families and people who loved the characters that killed by Nana, Nana is deserved to has redemption but punishment is inevitable. I bet she will beated up or tortured by Nanao until Nanao deciding he will forgive Nana and Nana will go to jail or executed in the end of manga for her crimes. But I don't want Nana to die, punishment is okay but please don't give her execution, she is just a victim that framed by Tsuruoka to kill under his order.
