By order of the head of the demon slayers, Kagaya Ubuyashiki. Mitsuri was sent on a mission, she was as a bodyguard to a wealthy family that had been in existence for many generations since the Sengoku period.

Mitsuri was so excited, she thought how incredible it was to meet such a respectful and wealthy family. When she arrived at the place indicated to her, Mitsuri was amazed by the mansion. The mansion was large and well preserved when it was currently in the Taisho period.

She was greeted by the servants of the owner's mansion. Mitsuri understood that her mission was that she would have to protect the owner of the house from the demon who came to this mansion 4 days ago.

When the servants brought Mitsuri to shoji's door, one of the servants knocked and opened the door for Mitsuri. When Mitsuri came in, she was told to expect the owner of the estate and Mitsuri nodded with a smile. The servant closed the door and left her alone in the room.

Mitsuri: How beautiful...

She was curiously examining the interior.
