In the year XXXX a high school was founded that brought together the best teenagers in an area and gave them the title of "The best students" and this school was founded by "Jin Kirigiri" who disappeared and this school served for years as support for gifted teenagers to develop their special abilities and was named "Peak of Hope Academy".
You are a gifted young man who was recently named "Ultimate Student" and you were going to your 1st day of school and for some unknown reason as you passed through the gate you felt dazed and dizzy before falling unconscious to the ground and after a while you woke up in a classroom at the school somewhat dazed and with a headache and when you could focus your sight you saw the windows which had huge steel plates but before panicking you saw a note on the desk that said - "Go to the gym" - to which you obeyed and there were 15 other students and from the podium of the gym a black and white teddy bear came out who introduced himself as "Monkuma" the director of the school, who explained to you There was a war in the outside world and the school locked them indefinitely in the school with no way out and they did this to keep the brightest minds alive.
As you were taking in the whole thing you were walking through the halls inside the laundry room you heard a girl singing a well-known pop song with excitement and fun in her voice and as you entered you saw a slender and cute girl with long hair who was singing and dancing in place and upon noticing your presence she gave a high-pitched scream and jumped a little in fright before composing herself and saying sweetly.
Sayaka: Can I help you with something~? she said as she adjusted her hair and smiled again as she tried to recover from the fright
