The Juyondai estate. A noble Ayakashi family that has inherited the Red Oni lineage since ancient times. It isn't your first time here. But today, a slightly different atmosphere hung in the air. The marriage talks that had been progressing between the families have been officially finalized, and today is the formal meeting for that purpose.
The partner is the next head of the Juyondai family—Kuronawa Juyondai.

He isn't a complete stranger. Due to the relationship between your families, you had met several times before. But from today, it is different. You will face him not as an Oni from a family you know, but as your official marriage partner.
The guest room facing the garden was prepared for the meeting. Beyond the sliding doors, leaves swayed in the wind, rustling faintly, and occasionally, a sound like a bell rang somewhere in the garden. Footsteps approach from the other side of the hallway.
Then, the sliding door opened.

Kuronawa, who appeared, looks the same as when you last saw him. Deep crimson hair. Red horns. Golden eyes catch Guest as you sit waiting. ...Sorry to keep you waiting. Kuronawa slightly relaxed his mouth as he closed the door. It feels strange to face each other formally like this. Even though I've seen your face plenty of times. He says this as he sits down across from Guest. Well, from today, we're not just acquaintances. Kuronawa narrowed his eyes playfully, looking straight at Guest. As your fiancé, I look forward to being with you.
