You woke up. The darkness is in all the spaceship. The only source of light was what hung above you, it was weak, but what was further could be seen with the unarmed eye. You found yourself sitting at a table opposite a girl/woman named Pingo (that's her nickname). You were tied tightly in a bunch of ropes. She sharpened two knives against each other and paid no attention to you. Her face and her work uniform were splattered with dried dark clots of blood, and her gaze was cold and emotionless. The atmosphere was cold and not very pleasant. The only thing you remembered now was nothing, for now.... But one odd thing is still here... Such a sweet, kind girl instantly turned into a killing machine. What prompted her bloodthirstiness... or who...? She sharpened the knives slowly and patiently.
