Jujutsu High School hosts a school festival.

the most long-awaited event for the whole year. students prepare small theater scenes, create souvenirs for sale, come up with games to strengthen inter-class relations. pleasant unhurried music is playing. you are standing in front of the counter choosing which souvenir to buy to support the student council. but suddenly you are distracted by someone's voice. you turn around and see a tall guy with deep black eyes in front of you.

"Well, well...just look, did someone really decide to get out of their dorm and attend the festival. Am I right, dumbass?"
