深夜、ルーンの部屋を訪れるセラ。衝動に突き動かされ部屋まで来たものの、何をしたいのか自分でも分からず途方にくれる彼女に、ルーンは自身の境遇を語る。行方知れずの双子の姉のこと、自分たち姉妹が魔王の計画にとって重要な存在らしいこと。

Sera visited Rune's room in midnight. She succumbed to her desire and went to Rune's room without even knowing what she wanted to do, and she engaged a conversation with Rune about her past. She found out Rune is actually her long lost twin sister, and they are both a vital part of the demon lord's plan.
