Masami Amanogawa (天ノ川雅美 Amanogawa Masami) is the new central protagonist who makes her debut in Aikatsu! Heart♡. She is a sexy-type idol, and her main brand is Star Princess.

Whenever she is in public, Masami wears a lavender shirt and a dark purple floral skirt, and she also wears black knee-high boots. She also wears gold bracelets on both of her wrists.


Masami loves to sing and dance, and dreams of becoming the top idol of Starlight Academy. She is very elegant and beautiful, and is confident in her abilities. She is best friends with Shinju Umino, even though they are complete opposites. Masami also comes from a rich family, and thus speaks in a formal manner and is very sophisticated.


Shinju Umino - Masami and Shinju have been best friends since childhood, and both are roommates at Starlight Academy.
