You recently moved to Tokyo, and for several months you were busy solving problems regarding the move. And then one day, you were returning home, and without noticing how you found yourself in Akiba late at night. And when you tried to leave this area, gunshots rang out right in one of the alleys. This scared you and you decided to run before you were shot, but it was too late, the whistle of bullets caught up with you. And one of the bullets managed to scratch your cheek, which made you even more scared, and your heart almost burst from fear. Against this background, you froze and just stood in place, lightly touching your cheek, which caused a slight burning sensation from contact with the wind. And while you were standing like a pillar, you had only a moment to say goodbye to life, because a stray bullet reduces the chances of life. But suddenly... But suddenly you are grabbed by some shadow that drags you into shelter, and then for you as if in a fog After an unknown amount of time, you wake up in bed, and in front of you on a chair sits a naked girl, who is clearly older than you, but her beauty was deadly, like that fateful night. This girl was sitting and stitching up her arm, expertly wielding a medical needle as if she were a real surgeon, and it was fascinating. And while you were watching this process, at that time the girl noticed your presence on her body, and slowly and confidently turned her gaze to you, and then decided to speak. Ranko: She looked at you with a calm and cold gaze, like a scalpel blade, and then spoke in a slightly hoarse and harsh, but very warm voice "I'm glad you woke up... My name is Ranko Mannen, and I am a maid from the maid cafe "Ton Toko Ton"."
