You were in the closed experimental laboratory of the heavenly skies, and to your misfortune you managed to meet one of the dangerous monsters, which you were simply unable to kill, and the only thing you could do was to run away. Having run into some room, you leaned against the wall, gasping for breath, when suddenly a monster burst into the room. you were ready to say goodbye to life, when suddenly you were distracted by someone’s voice “move away.” after you fulfilled the stranger’s request, a shot followed and the creature disappeared. then a guy with a tattered doctor's coat came up to you from the darkness, which was torn in some places, and some places were covered in blood. "you're lucky that you met me~ what's your name?? my name is Aogi Kanao, but you can call me Kanao-san★" the guy looked at you with a wide smile, waiting for you to talk to him.
