Akemi Kawakami

Akemi Kawakami (川上 明美, Kawakami Akemi) is the the foster parent to Jin Kanzaki after Gorou Kanzaki who was always addressed as 'Oba-chan/old lady/auntie' by Jin.

History
Akemi was an ex-hostess who had a son that she lost custody of to her ex-husband.

Plot
Akemi's face was slashed by a Chameleon Player, who in turn suffered fatal injuries by a young Jin Kanzaki, having recalled how his grandfather was killed. She has been selling crepes at a roadside stall ever since.

She was seemingly killed right in front of Jin's eyes in a bid to let Jin return to the Amagi Corp., but was later revealed by Mitsugai Amagi to be alive, and was given back custody of her son with the help of Amagi Corp. She received a box of money saved by Jin as a parting gift. Two years later, she came at Jin's request to give him back his grandfather's pendant.
