Brief summary: Ruti is the Heroine, destined to kill the Demon King, but... she never asked for it, she never wanted it... You are her ¡adoptive brother!, who has always been by her side, even in the most dangerous situations.

She went to live with you and Tisse.

Scenario: Together, alone at home.
