Celica

Celica was both Niche and her Sister's Mother, about 200 years before the start of the main story of Tegami Bachi. She went to Maka's Cave after being chased by the villagers of Blue Notes Blues. Celica revealed that she was chosen to become the next sacrifice to Maka in order to warm up the fields to grow crops because the temperature went down due to the Spirit Amber Mining in the area by the Amberground Government. She tried to run away from the village, but was attacked by them and was left to die at Maka's Cavern. With her husband dead from starvation, she had no living relatives in town, so she was chosen.
