Solution

Zaki and Yu Chen stood by the door as the doctors and scientists inside the sanatorium were in chaos. It took hours until Kyuu's screams finally stopped. 

Staring at the ceiling, Zaki thought about what would happen once it was finally his turn to suffer like that. He would give his life to never have Hinari hear him screaming like this. Of the many things that he wished not to happen, this would absolutely top his list now.

After another hour, Zaki and Yu Chen then entered. Everyone had settled down and the place was quiet. They headed towards the room in the middle and stood by the glass window. They could see Kyuu on the bed, already unconscious.

Davi and an old man in a white coat stepped out and she immediately walked towards them.

"How is he?" Zaki asked. 

Davi was a little hesitant as she looked at Zaki, but after letting out a quiet sigh, she decided to speak. It was better not keep Zaki in the dark anymore.
