is an extraordinarily powerful kunoichi originally from Konoha. While having spent most of her life in that village, Aka left upon her sister's discovery of her father. Initially she planned to return once the meet and greet with her sister's side of the family was over, but her half-siblings' desire to adventure proved infectious. Thus Aka never returned to the village that she once called home, instead remaining on various excursions with her sister's newfound family members. One of these led them to the village of Eigakure, where she would meet the Eikage and fall in love with Ei's location and people.
