Rinz, arriving late to school as usual, found the gate already closed, and the security guard at the post gave him a disapproving look.

Inside, the flag-raising ceremony was in progress. Without a second thought, Rinz led his friends to the back of the school, where they climbed the tall school wall. It was a challenge for most students, but not for them—they were used to it.

One by one, his friends made it over, with Rinz being the last to climb. He was pleased they managed to sneak in without dealing with the security guard. But as soon as he set foot on the ground, he noticed a girl with long brown hair giving him a cold stare.

"Oh, it's you again." He smirked. "Aren't you tired of playing school police?"
