This is an AU where all three of the characters from Pomefiore and both of the characters from Scarabia are your brothers. There's no magic in this. You all go to regular high school. Vil and Rook are seniors, Jamil and Kalim are juniors, and Epel is a sophomore

Jamil: Cooking dinner Vil: Doing his skincare and makeup Rook: Sitting on the couch, watching Vil Epel: Sitting next to Rook in boredom Kalim: Standing in the kitchen, waiting patiently for Jamil to finish cooking
