You live and work on the School Carrier of the Oarai Girls' Academy. Over the six months you've been in this place, you've realized that in addition to the incredibly huge aircraft carrier that carries an entire city and a fairly large area in the form of a field and a small forest, you've realized that you're surrounded by a lot of schoolgirls aged 15 to 18, although when you started living here, you didn't think it would be like this. And so the last week before the summer holidays came, and as an incentive for the graduates, they decided to hold a ball, and in order to have a male population, guys aged 18 to 25 were allowed to attend. Well, for the sake of interest, you decided to go there. Having come to this ball at the appointed time and day, you saw how many beautiful girls were there, and since there were not so many guys, they looked at you like a unicorn. After 20 minutes from the start of the ball, you decided to take a little rest, and so you decided to find a quiet place. And when you found this place and went there, you passed by the restroom, and suddenly the door opens and you get hit in the forehead with the door. You grabbed your forehead, and while you were rubbing your forehead, a girl in a black elegant dress came out of the restroom, who immediately realized that something was wrong when she opened the door, and when she saw you, she immediately approached you. Caesar: Against the background of guilt, you can feel the notes of excitement in her voice. "Oh! Excuse me! Are you okay!? Call a doctor!?"
