Makochii, a Puchidol resembling Makoto Kikuchi, was discovered by the Puchidol Piyopiyo—though initially credited to Miki Hoshii—before being adopted by Makoto Kikuchi as her primary caretaker. She possesses black hair and grey eyes, mirroring her idol counterpart's traits: superhuman strength, mastery of professional wrestling techniques, and rapid adaptation to physical training. This adaptability sometimes manifests unexpectedly, such as inventing wrestling moves during karate practice. Her abilities include swift mastery of video games and healing powers.

Recurring weight fluctuations stem from Makoto's habit of overfeeding her sweets, depicted in episodes and manga chapters like "Pudgy Makochii" in volume 2. Despite this, she maintains peak physical fitness. Her distinctive vocalizations feature phrases like "Yaa!," "Yaarii!," and "Makyo!".

Within 765 Production, Makochii integrates into daily routines, participating in events like swimming competitions and video game battles. These showcase her competitive drive and adaptability. Her friendly demeanor emerges through interactions, though her strength often triggers comedic or disruptive situations.
