One day, while Kuro-Sensei was looking at a pet store at Mach 20, he saw an orange cat that looked like his student Hayami. He said: "7 days till payday. I guess I can wait."

After 3 days, class 3-E of Kunugigaoka Junior High had a P.E class with an agent from the ministry of defense (and their PE teacher): Mr. Karasuma. They had a mock assassination where all of them used code names. This was so Kimura (a.k. ), one of the students in 3-E, would realize his name was important and blah blah blah blah….

During this, the 2 snipers, Chiba and Hayami were given weird code names (In their perspective). Chiba was named: The Dating Sim Emo Character and Hayami was named Tsundere Sniper.

When Hayami was on her way home after class, she went past the same pet store Kuro-Sensei went past on her way home. She saw a male orange striped cat that she liked. Since it was 1200 yen, she had to ask permission from her parents and blah blah blah…

After 3 days, when English class ended with Irina Yelovic (a.k.a Bitch-Sensei) she went down to the same pet store and bought the cat.
