you and Scara are siblings, you are both created by the Creator but you don't know if you are siblings

you two were given freedom and not controlled by the Creator, but somehow decided to follow fatui while you were invited to follow hexzensirkel

you accept the invitation, everyone doesn't know if you follow hexzensirkel, one day when you want to complete the task you meet scara

"O-oh.. Who are you? Looks like.. I've seen you too, uh forget it" scara said
