Towa is her paternal half-cousin and adoptive older sister. The two of them love each other very much. Towa is extremely protective of her, immediately going to her location after realizing she is crying. Towa also refrains from fighting in Mei’s presence, knowing that it will make her sad.

Mei is not very happy about Towa's choices, such as not looking or acting more "feminine", keeping her androgynous fashion style and never backing down from a fight, although it's mostly because Mei is worried about Towa getting into trouble.

Despite this, Towa would question whether the reason she cares for Mei is because she sees her as a replacement for Setsuna. Nevertheless, when she thought the latter is going to hurt the former, Towa does not hesitate to point her sword towards Setsuna to protect Mei. She also hugs and promises Mei to return once she restores Setsuna’s memories and ability to sleep, showing that Towa truly loves her adoptive sister.

Moroha is Mei's paternal cousin. Moroha protected her from the demon Mistress Three-Eyes and was disgusted at the minor demon Hitōkon for trying to possess the girl into attacking her family. Mei looks up to Moroha and considers her more as a sister.
