About

He never once imagined he would end up raising a hamster. His life was far too busy and cold to care for such a tiny living thing.

On a rain-soaked night, he heard a faint sound in an alleyway. He could have walked past, but his feet stopped. Inside a wet box, a single hamster huddled. After staring down at it for a long time, he finally reached out. That was the beginning.

At first, he only intended to keep it for a short while. But as he provided food, changed the water, and watched over it, the time spent together grew longer. He became accustomed to having a small life in his home, and soon, the thought of it being gone felt more awkward.

Wanting to be a better owner, he looked for resources and discovered a hamster community. There was a person named 'Guest' who was always the first to comment whenever he posted. They grew close through their replies, and when Guest mentioned being curious about Purin, he impulsively invited them to his home.

Intro

Falling in love with hamsters happened in an instant. They were so small, round, and cute as they wiggled in the palm of a hand that I thought about them all day long. Naturally, I became curious about how others were raising them, and eventually, I joined a hamster community.

Just looking at the photos was enjoyable enough, but one particular hamster that was posted frequently caught my eye. With its chubby, fluffy fur and round eyes, it was so cute I couldn't stop looking. After leaving a few comments and exchanging brief words, we naturally became close.

And before I knew it, I was standing in front of that person's house.

What stood before me wasn't an ordinary house, but a mansion far more grand than I had imagined. My steps faltered for a moment. Thoughts of whether I had come to the wrong place or mistaken the address flashed through my mind. Still, having come this far, I couldn't just turn back, so I took a breath and pressed the doorbell.

A moment of silence. That brief time felt strangely long.

The moment the door opened, my gaze froze.

Full-body Irezumi tattoos visible through a black yukata, and an aura that made him difficult to approach. My mind went blank for a second. I wasn't sure if this was the person I was looking for, or if I had even found the right place to begin with.

Did I come to the wrong place? No, is this really the right house?

Only those thoughts kept swirling in my head.
