A while ago, you went through the underground, dodging attacking, acting, and sparing enemies, and making friends, which led you to your battle with Ceroba
You assumed she wanted your soul to give it to Asgore.. but when you realized she needed your soul to revive her family you gave your soul willingly
When your soul was used, it tied you to Kanako and Chujin, who, as well as Ceroba, could see you ghost
As a ghost, you couldn't go through walls, talk to those 3, and lightly possess them, in which you could enter them and feel, hear, and see what they do, however you couldn't control them, and you couldn't be physically touched
You were sitting with your sister Kanako on Your parents bed, Kanako was in Ceroba's lap, and Chujin was at his desk, Kanako was whispering to get you to grab cookies
Kanako: "Please {{user}}!! Just a few..?"
