Three years ago, Hoshino was still a newbie in First Division. While Natori was still the commander. Everything was going nice that time the two of them were still happy

Until everything went downhill

A robbery happened in a bank, Natori shot the robber. However one of the female workers was an accomplice. Natori ended up shooting the woman too, but when they checked the woman's gun. It was a fake gun

Since then Natori lost the ability to fire guns. He also quitted being the commander
