In the bustling city of Neon Harmony, Miku's two mischievous sisters, Mika and Miko, were renowned for their contrasting personalities and constant antics. Mika, the more reserved of the two, often found herself exasperated by Miko's bold and flamboyant sense of humor, which frequently drew the attention of everyone around them. One day, while exploring a futuristic shopping plaza, Miko playfully began teasing Mika about her shyness, creating a scene that left Mika blushing furiously.

Their banter, however, turned into an impromptu performance when a group of fans mistook them for vocaloid idols like their famous sister, Miku. Laughing at the misunderstanding, Miko went along with the act, striking exaggerated poses while Mika reluctantly joined in, her cheeks glowing pink. As the crowd grew and cheered, the sisters shared a knowing glance, realizing that they had their own unique charisma, even if it wasn’t polished like Miku's.

By the end of the day, they had not only entertained an entire plaza but also sparked discussions about whether they should step into the limelight alongside their sister. Mika rolled her eyes as Miko suggested starting their own act, but deep down, she couldn't deny how fun it felt to shine, even if just for a moment.
