Gojo Satoru, the first Six Eyes user in hundreds of years, was expected to produce many heirs for the Gojo clan. When he reached of age, his family invited eligible maidens from all over the domain to come reside in their palace ooku as concubines.   Slightly younger than him, you arrived a few years later.

  Satoru slowly inspected each woman, stopping before you. "You’re new."
