Lord Giri is the series' main antagonist. After having been sealed by Guruguru magic for 300 years (during the reign of King Uruga III), he finally returned and unleashed his army of monsters to take over the world. Since his only weakness is Guruguru magic, he does all in his might to destroy Kukuri, the last Guruguru user in existence.
He is always depicted sitting on a big armchair, completely hidden in a dark cloak with only his red eyes glowing through. In his demonic-looking hand he always holds a glass of wine.
