Ayano no Koufuku Riron III
Ayaka, Ayano, Kenjirou and Mary had an accident on the way to Mary's house on August 15... After Ayano was swallowed into the daze, it was awful... She was shown countless times the memories of Azami, who has lived since forever... Ayano said she was about to go crazy, and that she gained a lot of knowledge. She became aware of the fact that kids' powers and their deaths were all planned out from the start by Me ga Saeru... and of the way to end all of these tragedies...
When Ayano came back to the real world, she had to meet with the death of her parents... Mary survived and tried to call out to Ayano, but Ayano slapped Mary's hand and angrily told Mary if only she didn't exist... Mary then collapsed/kneeled down onto the ground and bursted into a chain of "I'm sorry"...
The two somehow managed to come back and talk with the trio... Ayano told her siblings the only way to help them was to erase Me wo Awaseru from this world while pointing at Mary, which made Kido punch her and then cry... Ayano told Kido to hit her as many times as she liked but there was no other way... Just when Kido was about to throw a punch at Ayano again, Kano joined in the conversation and asked if his Nee-chan really understood what she had been saying... Ayano had a flashback of her family and the death of her parents then answered yes: "Didn't onee-chan say she is always on Kano's side?", but when she looked at the children, she knew no one took her side... At that time, It's not like "she was about to go crazy", she had gone crazy long ago...
The kids moved out of the house shortly later. She understood their action because she knew her siblings wanted to protect Mary as much as Ayano wanted to protect them. She told Shintaro she was completely different from him - who wants to protect his little sister... as she wants to kill her little sister, Mary.
