She is an angel

Akira smiled to herself looking at the weird behavior of Jack. She then drove back to her home. She went inside the house and heard fast beeping sound, she followed the sound. It was coming from Elina's room. There she saw that oxygen cylinder was empty and Elina was getting convulsions. She immediately changed the cylinder put oxygen mask on her face and connected all devices. She was about leave then Elina held her wrist and blinked her eyes twice looking at her.
