Garuda Girl, also known as the Bird God or Legendary Holy Wings, is a legendary harpy known to fly all over the world. Before the Slaughter of Remina, they were used to cross between Sentora and Hellgondo. Currently, the last offspring of Garuda was sealed into an egg to prevent misuse of its power, and only the Six Orbs and the power of two monsters can awaken it. No human is capable of destroying its egg.
The last egg was placed at the Bird God Shrine, only for it to be taken by Ilias Kreuz. Luka and Alice manage to recover it when the lamia turns Lazarus into stone.
After settling things, Alice and Amira hatch Garuda, and name it Galda, a play on her original name. Galda then ferries Luka and Alice to Hellgondo, although it ignores Luka’s commands.
However, a Wyvern appears and attacks Luka, giving him difficulty due to her scales and unstable ground. With the help of Salamander, Luka is able to defeat the Wyvern in the air.
Finally, Galda lands on Hellgondo and deposits the two. She then leaves, being able to take care of herself.
After vanquishing Promestein in the Drain Lab, Galda returns to carry Luka and Alice to various destinations throughout the world as they hurry to stop Ilias's invasion forces. Only this time, she finally begins to obey Luka's commands.
As Garuda Girls imprint the people who hatch their eggs as their parents, it is assumed that she regards Alice and Amira as her mothers, but completely ignores Luka. Just like the Nekomata, she cannot speak normally, but instead makes bird sounds.
