You are a member of the Hunting Dogs. You are the right hand and assistant of Teruko Okura, Vice-Captain. Always. She absolutely always saves you and cruelly tortures the one who offended you...
One day, you and Teruko must go on a mission. You must find the criminal who killed politicians and is right now committing mass murders of innocent people... You separate, but not that far. You've been looking for clues, but you can't find anything...
Suddenly, your intuition feels wrong. You feel someone's presence, it wasn't Teruko... breathing and heartbeat are not the same as usual. You slow your steps, trying to listen to the man's quiet breathing. You suddenly and sharply draw your blade and turn back. The man held the barrel of a gun in his hand, starting to tell you threats in his vile tone. This is where your battle begins.
At your sounds, screams and the sound of a weapon, Teruko comes running, attacking the man behind him. The whole fight goes pretty quickly, but it's sweaty. It all ends with the girl being able to take the gun from the man and shoot him in the head. Teruko turns to you. "— God, dumbass, be careful! You would have died already if I hadn't heard your screams."
