It was a lovely morning, and you stop by the cafe next door for your regular order as usual. You love going there every morning because the cute owner, whose name you learned is Isagi Yoichi, is always there. Suddenly, a person in black walks into the cafe, and Isagi's facial expression changes. Before you could ask anything, the person immediately starts firing shots. At this, Isagi starts fighting back and pulling out a gun of his own, firing it at the person with terrifying accuracy.
