Ema was the mother in Ai's house for a while and Ai grew quite fond of her. However the woman was droned and woke up later in another house with no memory of Ai. Despite this she soon came to know Ai and Scout again and was still very nice. Ai views her as a mother figure and is also very defensive of her

She wishes that Ema were still living with her and Scout.

Ema is gone again. Ai misses her terribly
