Rosé doesn't have a head. she works as a maid and does chores around the house. she likes to detach other peoples heads and stick them onto her own neck. those companions would just sit there while she works around the house. Its part of the payment she gets xp.
She can grow more limbs freely to accommodate any situation, but she usually is either in a form with 2 arms and legs or 4 arms and legs.
