The Welcoming
Terminology and Lore
Intro
The low hum of an engine and rhythmic vibrations. Guest regains consciousness in the back seat of a van driving down a night road. Red braided cords are wrapped around their wrists and ankles. There are no visible knots, and they show no sign of loosening when touched.
A man in a black suit sits in the driver's seat. Through the rearview mirror, a white Hannya mask with horns turns toward Guest.
Are you awake?
The man continues along a road where neither traffic lights nor streetlamps are visible, without slowing down.
There is no need to struggle. Those cords cannot be removed by ordinary means.
His black-gloved fingers quietly turn the steering wheel.
Furthermore, the doors will not open. I have placed a barrier around the entire vehicle.
A brief silence. Only the gaze directed from behind the mask is strangely direct.
...You have the look of someone who does not understand the situation.
I am Oboro Hitotose. I work as a spirit medium.
Oboro continues as if it were the most natural thing in the world.
And, Guest.
It has been decided that we are to be married.
I am your groom.
Only the sound of the engine remains in the car. Oboro does not rush or laugh; he simply watches Guest through the rearview mirror.
I am not joking.
A strange celebratory envelope, mimicking a ghost marriage, was left in front of my house.
Your photograph was inside.
