Oceana Louvier is a main character in Endless Ocean:Blue World. She is the granddaughter of Jean-Eric Louvier, and plays a big part in running L&L Diving Service. She is fairly young, roughly 16-17 years old during the game. Oceana is one of the diving partners that can assist the main player.

In-game description

"Jean-Eric's granddaughter, who works as a dive guide with L&L Diving Service. She grew up in the Pelago Commonwealth with the South Pacific as her personal playground, so Oceana is a first-rate diver. Usually bright and cheerful, she also has a slightly solitary and obstinate side, perhaps because she lost both parents when she was just a young girl. She also loves the Internet and kittens." 


Early Life

Oceana grew up in the South Pacific, allowing her to get to know the Ocean well and gain plenty of experience diving despite her young age. Her father died when she was very young, perhaps as a baby, toddler or preschooler.

Abilities and Traits


Oceana is a pretty friendly individual. She is always willing to help her friends. She is usually fairly bright and cheerful, but does have a more emotional side, possibly due to her losing both parents at a young age. She also likes the Internet, kittens, and sea slugs. She seems to have a strange affection for some of the weirdest

creatures, such as giant isopods . She is also smart, as she worked out the origin of the Song of Dragons before even Hayako Sakurai could.

She is known to have a deep anger for the thoughtless damage that the human race inflicts upon nature and wildlife. She wishes she could do something to end it all.


Despite her young age, Oceana is a very skilled diver, and even helps to provide training for new divers. She also has a talent for spotting small areas on the sea floor containing small creatures.


Out of the characters in the game, Oceana has some of the strongest relationships with the members of the L&L Diving Service. She is very close to Jean-Eric Louvier, largely because, having lost both her parents, he is the only family she has. However she does sometimes get annoyed at her grandfather's overprotectiveness. She also develops a strong relationship with the player character, who becomes a sort of role model figure to her.

Diving Abilities

When you pick Oceana to dive with you, she is able to give you tours of the current area you're in. She will name landmarks and give information about each one. She can also go into small holes, which has been helpful throughout the main storyline.


  • Oceana's name in the European version of the game is Océane Rouvier.
