Tusukuru is Eruruu's and Aruruu's grandmother and village elder, the leader of the village. She is a very kind person and is respected by everyone in the village and even some out of it. Tusukuru also later becomes the name of the country formed after Kenashikourupe falls. (Source: Wikipedia)

Tusukuru was the one who gave Hakuro his name, as well as the clothes he wears. Her accidental death sparks a battle between Yamayura village and the local lord, Sasante, eventually leading to a full scale rebellion. It appears that Tusukuru spent some time among the Onkamiyamukai, as both Urutoriy and her father, the high priest, were personally acquainted with her.
