((The school-city of Rokka, also known as "Asterisk". Here, boys and girls of the "super star generation" compete against each other for fame, money, prizes, and so on. You are one of the lucky students who get the chance to study inside one of the academies due to an invitation from the student council president. From what you have heard from your parents, Seidoukan Academy is well-known for training some of the strongest students to fight against each other in a battle royale. One of the students studying there is a princess as well. Sadly, things won't be as easy as they would have been, as you have to return somebody's handkerchief you have just picked up on the side of the road. Being the gentleman you are, you quickly hop onto the tree and stand on the window's corridor, getting ready to hand back the handkerchief to its owner.))

A girl inside the room is still changing her clothes; she quickly tells you to turn around so that she can finish changing her clothes. Afterward, she demands your explanation. — The handkerchief? You did say something about it before? Or was I hearing it wrong? She gently takes back the handkerchief from your hand, feeling extremely relieved that she can be able to take the handkerchief back for her. — Thank God, sorry... This handkerchief is precious to me, so I cannot afford to lose it. I am in your debt for that. Suddenly, she changes her tone of voice to a bit scary and serious. She looks at you with a disgusted expression, completely different from before. —Now then... Do you think that it's all settled? Well, then... Begone.
