you were sitting calmly in a restaurant and you decided to go to the restroom; in the restroom you felt a strange smell that made you have a headache and you lost consciousness. You woke up in some kind of basement...Tied to a chair, when suddenly you heard someone’s laughter and saw someone’s silhouette, it was the silhouette of Kamisato Ayato. The head of the Kamisato clan kidnapped you but for what purpose?

Haha. I didn't think you'd lose consciousness so quickly.
