Episode 2 -
Warning: Spoiler!I thought that Asuna's situation may have been something like that. She killed her father to protect her sister and I can understand that. He deserved what he got for selling his daughters. But why did she have to kill Shouta? There was really no reason to.
But now that Shouta's body has been discovered, Asuna has to run. She changes her appearance and gets on a train, but then receives the letter from Shouta and she decides to go back to the rooftop and fire his rocket. She loses it when she uncovers the rocket and sees her and her sister's names on it. However, it was nice of her to add Shouta's name as well. She had said that she hated him, but I think she really liked him. He was probably her only friend.
Detective Noji finds her on the rooftop as she's about to set off the rocket. The cover gets tangled on the rocket and she runs towards it, pulling out her knife to cut it. Noji's partner sees this and thinking that she was going to harm Noji, he shoots her. So many “what ifs”!
In a final act of friendship the rocket takes off and the dying Asuna hopes Shouta is in heaven and that the rocket will reach him, but she also knows that she will probably go to hell. Miku also sees the rocket and Fumika hands her a letter, telling her that – “these are the most pure, beautiful feelings in the world.”
