Yan Mama Rock 'N Roll.

Miyako Amano, the first president of the ladies "Haruya". Nowadays, she lives her life as the bride of "Matsumidoriyu". She vowed that she would be gracefully out of the office until the day her dad returned with her belly-bearing son Kentaro on the verge of her month, even when her beloved husband disappeared. However, the store was spotted by Sakamaki Kosan, which aims for local redevelopment! She obstructed a lot of business, and even Kentaro was kidnapped and once let go of the store's title, but Miyako finally got rid of the unstoppable harassment! She put an iron pipe in the 750cc and headed for a strange group of employees and a recapture of the title!
