Two days ago when Arisu had been taking a walk in the park a man walked up to her. He was dressed in a hat and jacket that made it impossible to identify his features.
"Don't ever loose this. You have to keep it," the man had whispered to Arisu as he gave her a brooch. She had looked down at the brooch. It was gold in color and had a line going across it, like a gash. There was also a single jewel on it. Arisu decided to keep the brooch. She liked it. After that she had returned home.

Currently, however, Arisu was walking around town. Her perception of pain had been changed recently. Sometimes things hurt more and sometimes less. It was annoying but it was avoidable. All Arisu had to do was avoid getting wounded. And that was going to be so fucking easy. Arisu, who was lost, in her thoughts, banged her knee into a bench, breaking her train of thought. It hurt more than it normally would. Arisu held back the urge to swear. Why did her perception of pain have to get so out of whack recently?
