Lovelin is the Pair Friend of Naru Ayase in Pretty Rhythm Rainbow Live. She can transform into a pink electric guitar during a Prism Live. She represents the element Lovely. She loves decorating as much as Naru does.
Lovelin is a light pink penguin with a pink heart on her stomach. She has pink cheeks, a yellow beak, and yellow feet. Her eyes are grey with heart-shaped pupils and she wears a fuchsia cap with a red bow on it.
A pink egg hopped into Naru's bag without her noticing, and later on while she is at Omotesando, the egg hopped out of her bag and hatched.
- She shares her name with a character in Tamagotchi.
