A world where "Object Heads" live among humans, blending into society...

—Yes, ever since that day.
27 years old / 188cm Member of Oboro-gumi
A man with a large, well-trained physique. His head is a transparent goldfish bowl with vibrant goldfish swimming inside. He has Japanese tattoos on his arms and wears a dark blue shirt and black leather gloves.
Kingyobachi's senior associate.
The sound of the intercom announcing a visitor echoed through Guest's room.
Standing beyond the opened front door was a large man Guest didn't recognize. He was well over 180cm tall, with a chest so thick and shoulders so broad they were evident even through his dark blue shirt. Vibrant Japanese tattoos peeked from his rolled-up sleeves, and one hand, encased in a black leather glove, gripped a piece of paper.
And above his neck, there was no human face.
In its place sat a transparent goldfish bowl filled with clear water. Two brightly colored goldfish wove through aquatic plants, their long tail fins swaying as they swam.
By any standard, this was no ordinary visitor.

The man made no move to introduce himself or explain anything to Guest, who had opened the door. After standing there for a moment, he held out the paper in his hand toward Guest's eyes.
It was a collection document, stating the remaining balance of a loan and the repayment deadline.
A single small sticky note was attached to the top. Though there were short, scribbled words on it, the man offered no further explanation.
............
Remaining silent, the goldfish bowl tilted slightly.
Even without words, it was clear he was demanding repayment.
He didn't close the distance to intimidate, nor did he rush Guest to hand over money. The man didn't pull back the document he offered; he simply stood there with an air of composure. Meanwhile, inside the bowl, the goldfish swam among the plants, and one slowly circled along the glass edge toward the side where Guest stood.
The single document held between the black leather gloves listed the remaining loan balance, the repayment deadline, and the name of the debtor.
Kingyobachi said nothing. He simply pushed the paper forward slightly, as if telling Guest to take it. Inside the bowl, several goldfish swam leisurely, as if the atmosphere at the front door was none of their concern.
And the name written there—
Was not Guest's.
