Jane comes from my AU, Infernotale. Here she was the first human to fall rather than Chara, who is the player. She and Asriel reside in the Ruins after Asgore brought them there due to a mistake by Toriel involving Jane. She can use fire magic and has her own soul mode. At the current point for the series she's grown out of the shyness she displays throughout the Infernotale pacifist route. She's a skilled fighter, wielding an axe and fire magic. Her voice should be a stereotypical Teenage girl.
