'''Sage Luka''' is a major supporting character in ''[[Secret of Mana]]''. She is the 200 year old Sage of Water, but looks no older than 18. She is a friend of Gemma and Undine.

[[Randi]] arrives at the Water Palace where Gemma awaits near the main entrance. While exploring the temple, the young hero seems lost and decides to ask a young maiden Luka’s whereabouts. Gemma reprimands the lad for being so casual and properly introduces Luka to Randi, who is shocked to see a young girl being at least 200 years old. Gemma then informs the sage that monsters are invading villages. Luka replies that she is aware of that since the ebb and flow of water brings me news from around the world. It’s because Mana’s power is growing weak that the young hero was able to remove the sword and when he did, the balance of Mana in this area shifted and made monsters reappear. Luka adds that there are enemies that seek to steal away the power of the legendary blade. By defeating those creatures, Randi can restore the power inside the sword kept inside orbs, just like the one the young lad found upon defeating Mantis Ant. The sage continues by telling Randi to seek the hidden orbs that can power up the blade and find someone that can forge the sword by releasing its stored power. She then wishes Gemma goodbye as he heads out to Pandora to seek an audience with the king and warns him about the [[Empire]]’s schemes to revives the [[Mana Fortress]]. Randi is surprised to hear about the same name mentioned in fairy tales, but Luka reframes it by telling him that the Mana Fortress is real. She adds that the Empire is going to unlock the seals from the world’s eight [[Mana Seeds]], remarking that strangers have already been lurking around the Water Palace. Before leaving, Gemma advises Randi to head for [[Gaia’s Navel]] where he will find [[Dwarf|Dwarves]] that are knowledgeable about weapons. After the old knight exits the temple, Randi finds himself alone with Luka, where he inquires about the Mana Sword’s purpose and the Fortress. He learns that he must become a hero worthy of the sword and that eons ago, ancients used the Mana Fortress in their final battle but failed to do so because of the inability to control Mana. Only the Mana Sword saved the world in the end. Luka then orders Randi to hold up the sword against the Mana Seed of water located behind her to synchronize its power within the blade. With a blinding flash of light, the Seed gives its power to the sword just as the sage mentioned. Sage Luka then prompts the young hero to visit the eight palaces throughout the world and gain their respective Mana Seeds’ power. She also entrusts a [[Spear]] blessed with holy water to Randi, noting that other weapons also gain power upon forging with orbs. She finally gives her last advice to the lad be telling him to search for the [[Underground Palace]] in Gaia’s Navel. The Mana Sword wielder agrees and heads to his next destination.

Luka makes a camo appearance in the online game, along with several Secret of Mana characters.

Luka's Japanese name sounds similar to rusalka, which refers to a female water spirit from Slavic folklore.
