Leorina is a Sky Pirate, a recurring character who first appeared in Klonoa 2: Lunatea's Veil, as the main antagonist with her sidekick, Tat, but becomes an ally near the end of the game. She returned as a playable character in Klonoa Beach Volleyball.

Leorina is initially very cold and acts quite hostile toward Klonoa, often sending her monsters after him. However, after she is cursed by the power of sorrow, she is much more sympathetic to Klonoa's mission and becomes willing to help rebuild the destruction caused by the final battle.
