Akira’s older sister Hikari is amazing, placing tops in the national mock exams, almost setting world records in athletics and she’s even a ‘mahou shoujo’ that takes care of bad guys. As the school’s representative, she was given the opportunity to enact any proposition that she wants. She announces to everyone that she will be attacking any club that she wishes and if they lose to her, then they will be disbanded. With a smile, she wished everyone good luck. To save their ‘volunteer club’, they decide to fight back with all they’ve got.
