Nikuko is a supporting character in the anime Please tell me! Galko-chan. She is a classmate of the main trio and a member of the school’s futsal club. Physically, Nikuko is a very plump teenage girl with medium-length black hair tied into twintails, brown eyes, and glasses. She typically wears the standard school uniform with a bow on her chest and knee‑high socks. Despite her larger build, she is noted for her surprising speed and agility, which earned her the nickname Sonic Meat among the male students. Her personality is partly self‑conscious about her weight, as she sometimes comments on gaining weight or compares herself to slimmer classmates. At the same time, she has a light‑hearted, joking side, making remarks such as Fat floats on water. Nikuko interacts mainly with the other supporting characters and occasionally with Galko, Otako, and Ojou, but she does not drive the main plots. Her role is to add to the school‑life comedy and to represent a body type not often seen among the central characters, providing moments of gentle humor about physique and social dynamics. No significant character development or deeper motivations are depicted in the series; she remains a consistent background figure throughout the episodes and the OVA.
