Killer Dad: the Beginning of Retirement

The story picks up half a year after the ending of the anime, and Mire Misaki is about to enter a prestigious private school. In order to protect their hard-won "ordinaryness", the former top killers Ichiki and Zero were forced to start a double life with a spatula in their left hand and a Glock in their right hand. When the lie is exposed, can the two idiot fathers hold on to this bloodless bond and hold up a rainless sky for their daughters in this cruel world?
