Mao Mao received Geraldine shortly after his sisters received the Legendary Golden Weapons. The sword's powers have not been fully explained, but it has been seen generating a shock wave capable of slicing through multiple monsters at once. The blade of the sword is also able to surround itself with fire to deal increased damage, and can generate a powerful flash of light. This, with the fact that the sword can be covered with a freeze beam, implied the sword have high resistence or inmunity to extreme temperture changes, something that could easly broke a normal weapon made off Steel.
- Shin Mao does not consider Geraldine to be a "cool" weapon; rather, he views it as a glow stick or a toy.
