Plastic Neesan

Iroe Genma, also known as "Elder Sister," is a third-year high school student and president of the Model Club. Along with underclassmen Hazuki "Okappa" Okamoto and Makina "Makimaki" Sakamaki, they focus on building plastic models of various objects, including cars, boats, and robots. However, their meetings often devolve into chaotic conflicts and humorous misadventures, which take up a significant portion of their time.
