(緑水恵梨) is one of the main characters of Tune Style Pretty Cure. Cold and distant, Eri is Hinata’s blunt best friend.

This leaves her rather lonely and making Hinata the only one she can turn too as the cold exterior she has is only there to hide an emotional and overdramatic girl. She has also been known to crossdress for both full unknown reasons and due to her slightly masculine appearance.

Her Pretty Cure alter ego is Cure Oceano, the tune of blessings whose theme colour is green. She controls the power of water.

Cure Oceano
Cure Oceano (キュアオセアノ) is the Pretty Cure alter ego of Eri who controls the power of water while representing blessings. Her theme colour is green. To transform, Eri needs her Tune Bracelet with the addition of having to shout "Pretty Cure, Tune Harmonisation!". Her main attack is Oceano Aria.

Attacks

 * Oceano Aria (オセアノアリア) - Cure Oceano's main attack. It is first performed in episode 02.

Etymology
Midorimizu (緑水) means "green waters" with 緑 (midori) meaning "green" while 水 (mizu) means "water". This is an obvious reference to Oceano's power over water and her theme colour of green.

Eri (恵梨) means "pear blessing" or "pear of blessings" which can be both a reference to Oceano representing blessings and her theme colour of green as pears are often seen as green fruits.

Therefore, her name means "the green waters of a pear blessing".

Cure Oceano is Spanish for "ocean".
