Makoto Kikuchi is an idol working for the talent agency 765 Production. She appears in the series as a human counterpart to the puchidol known as Makochi, whom she first encounters in episode thirteen of the original net animation. She is recognized for her masculine charm and boyish appearance, which draws a large number of female admirers and earns her the nickname the "pretty-boy idol" or the "prince" of 765 Production. Despite her tomboyish exterior, she harbors a sincere desire to be seen as more feminine and often struggles with the gap between her outward image and her inner wishes.

Her personality is marked by high energy, determination, and honesty. She is self-taught in dance and is considered one of the best dancers in the agency, displaying confidence in her physical abilities. She is also naturally athletic and enjoys sports. At the same time, she is a sensitive and caring person, especially toward her puchidol. She dotes on Makochi to the point of overfeeding her with high-calorie treats, which causes the small creature to gain weight frequently. In one episode, she attempts to teach Makochi karate, but the puchidol instead learns professional wrestling moves, demonstrating her surprising strength.

In the story, Makoto serves as one of the supporting human idols whose daily life is enriched by the presence of her puchidol. She interacts with the other members of 765 Production, such as Haruka Amami, and shares a close bond with her fellow idols. Her key relationship is with Makochi, whose friendly and affectionate nature complements Makoto's own protective and playful side. Throughout the series, she continues to balance her career as an idol with her personal quest for self-acceptance, gradually learning to embrace both her confident, sporty side and her softer, more feminine aspirations. Her notable abilities include strong singing and dancing skills, athletic prowess, and a natural charisma that appeals to a wide audience.
