Tsukasa Amane

Tsukasa is the twin sister of Tsukuyo Amane. She grew up with her father, helping him with the chores and errands at home and at his bamboo workshop where his apprentices live. She also handles the family’s finances, grocery shopping, and cooking. 

One day as she was heading home from school, a friend invited her to hang out but she declined due to the full workload she has at home taking care of her father’s apprentices. Her friend wonders if that’s the kind of thing a child should be doing, but Tsukasa believes it to be a place for herself. Her father is very outdated in his mode of thinking and believes that women should do all the housework. Tsukasa still loves and respects her father, but whenever she asked him about her mother, he refused to answer any questions. 

When everything becomes too overwhelming for her, she goes to a shrine to play her flute. She bumped into Kanagi Izumi one night on her way to the shrine, who told her to be more careful so late at night. Just then, Tsukasa saw someone who looked exactly like her but she disappeared before she could say anything. She spends all the next day thinking of the encounter when she bumps into Kanagi again. After telling Kanagi her story, Kanagi encourages her to go down to the shrine again and meet this doppelganger of hers. Tsukasa does just that and that night she runs into the girl who looks identical to her. They both start talking at the same time, and then she introduces herself as Tsukuyo Akidzuki. As they talk, they discover they were both named at the shrine and both play the flute. After examining the flutes and thinking of their names, they come to the conclusion that they must be twin sisters. 

Tsukasa’s father came from the poorer artisan ward whereas her mother came from the richer Mizuna ward. Due to their class differences, their marriage ended up falling apart and the two girls were split between their parents with the mother changing her last name. Thereafter the two girls began to hang out everyday together since neither of them had any real friends due to their after-school activities. But the more time they spent together, the more differences they noticed and the girls began to bicker. Eventually they had a large argument and decided to part ways.

After a particularly difficult day at home where she lashed out at her father, Tsukasa ran away to play her flute but decided to go to a lake since she didn’t want to bump into Tsukuyo. She ended up heading into a witch’s barrier where Kanagi saved her before she passed out. She woke up in the hospital in a room where she receives a call from Mifuyu Asuza, informing her Tsukuyo is in the hospital room next to hers. She walks over to Tsukuyo’s room and apologizes. The two girls accepted each other once more, but they were worried they would fight again like their parents due to their difference. Kyubey appeared and offered them a contract. Both girls wished to never hate each other and they’ve been almost inseparable ever since.
