Ai Hasebe

Age: 12

Ai Hasebe in the present timespace, is another of Haruka's classmates, and one of her best friends. She is an expert in soccer, and she has a crush on Isami that doesn't initially seem to be reciprocated. When Isami gives Haruka the same gift he gave Ai, Ai becomes briefly angry that she's shown no special affection.

In one future timespace, she is a respected soccer player, but damages her foot to the extent where she has to have it amputated. After becoming depressed, she almost commits suicide by jumping off of the hospital roof, but is saved by Isami. In Karasu's timespace, Ai is a respected scientist – Lady Amamiku – who attempts to use Haruka to save La'cryma, and still close to Isami.
