Onirei (also called Oniri in some languages) is one of the characters who appear on the Battle of Bracelets Series. She makes her first appearance on the Expansion Pack of Battle of Bracelets: The Cursed Death: BoB 3: Forgotten Dreams. Onirei is one of the Dream Bracelets, specifically the Desire Dream Bracelet, since she controls desires of humans. As the rest of Dream Bracelets, Onirei is one of the enemies who serves Hypnos, her father and indirectly Hades. Her main abilities are the Pleasured Illusion, which lets her turn everything into a happy place, full of beautiful things that will attack the enemy; and Sand Control, which converts her into a mass of sand that she can control and makes her invulnerable to any attack except and attacks. Her main weapon is the Desire Orbitars, a weapon that concentrates the mind power of Onirei to throw lasers and is stronger if the enemy is stronger.
