Aoi Aihana

Overview
The childhood friend of Haruto Soraki. Appeared in Haruto's dreams speaking of a promise to see each other at a well 7 years later to see the Akitsu Carnations bloom. She had the mysterious disease LMD and is the second longest stayer at the hospital (after Haruto), making her the first to meet him there. As the character glossary suggests, her loved ones likely died before she was admitted to the hospital.

Appearance
Aoi has short yellow hair, some of her bangs falling in the middle of her face. She has dark blue eyes and a large red hairbow with white on the tips, her most notable accessory. Her outfit consists of a white shirt underneath of a navy blue vest, some sort of red neckwear on there as well. Her skirt and socks are gray and she has on black shoes.

Plot
She goes through similiar events as Haruto in the timeline which she survived as Haruto told Dr. Ichiki to remove her memory in case such things happen. She was given the lungs of Haruto, curing her LMD. However she needs to take immunosuppressants every month as they are not fully compatible.

Experiment
She was in the experiment with Haruto (see page Haruto Soraki for more information) and presumably time leaped 17711 times into 7 years ago to save him (meaning she is probably 89,282 years old). However Haruto dies even if they both take the antidote (maybe from the method they took it). The antidote must be taken with water. But since there is no water nearby in the test chamber, they take it the emergency way (drink it like from a straw) which has risks.
