Meroko Yui
めろこ・ユイ
She has a hot temper and is sometimes very moody especially when it comes to her relationship with Takuto (despite her constant attempts to impress him, he doesn’t seem to notice her or have the same feelings).
Though she tries to help Mitsuki with her singing career, her ideas often get the girl into trouble.
In the anime, she is rather fond of changing her appearance into other characters, and her trademark phrase in the anime is “Mero Mero Change!”
