Like her friends, Jane highly cherishes her time within the Light Music Club and later their band Death Devil. She is a highly skilled drummer and dictates the rhythm during her band's performances. As a teenager, she appeared to be a bit timid as she clinged to Norimi Kawaguchi while she and her friends were scolded by their teacher Horigome.
As an adult, she is willing to play at the wedding of her friend Mihoko without concerns, unlike Sawako Yamanaka who is worried that her past might catch up to her.
So far, of all members of Death Devil, only Sawako and Norimi have their real names revealed. Jane and Della are only known under their stage names.
Although she made her real debut in the tenth episode of the second season of the anime, she can already be seen during the fifth episode of the first season. In said episode, she appeared in an image that shows Death Devil while they still visited school, as well as in Sawako's flashbacks.
