Upon arriving at the Advanced Nurturing School, Kirino Doppo awakened the Popularity Character System. As long as he performs well in the eyes of the audience, he gains popularity points, which he can exchange for abilities in the system's shop. To gain even higher popularity points, Kirino Doppo decided to cultivate his persona. Mysterious: He always speaks in half-truths and is a riddle teller. Kind: He lends a helping hand to those in trouble, even if it seems foolish to outsiders. Powerful: He uses popularity points to frantically enhance his combat strength, reaching a point where he can easily defeat Ayanokoji Kiyotaka with one hand. Over time, whenever the audience sees Kirino Doppo appear, they can't help but exclaim, "Everyone, come quick! The real protagonist has arrived!"
