Kiki serves as apprentice to Aries Mu, bearing the distinctive tilak dots on his forehead like his master and grandmaster Aries Shion. Identified as the youngest depicted Lemurian, he spent his childhood in Jamir, Tibet, under Mu's guidance. There, he encountered Dragon Shiryu seeking cloth repairs, initially teasing him before assisting in delivering the repaired Pegasus Cloth to Seiya. Kiki exhibits a cheerful, occasionally mischievous personality, yet demonstrates seriousness during critical missions and unwavering loyalty to Athena and the Bronze Saints. His primary non-combat role involves utilizing telekinetic powers to manipulate objects and people. During the Poseidon conflict, he transported the Libra Cloth to the Bronze Saints. In the Hades chapter, he detected the trajectory of Thanatos's attacks and participated in defending Seika alongside Silver and Bronze Saints. He never engaged in direct combat within the original series or its Hades OVAs, focusing solely on support functions. In the spin-off series *Saint Seiya Omega*, Kiki matures into the Aries Gold Saint, inheriting his master's responsibilities. He becomes the world's sole master cloth repairer and trains his own apprentice, Raki. Stationed at the first Zodiac Temple despite Sanctuary being under Mars's control, he repairs and enhances the Bronze Saints' cloths, citing loyalty to Athena and belief in the young warriors' potential. This action constitutes betrayal against Mars, leading to confrontations with Martian forces. His elemental affiliation is earth, and his combat techniques include Crystal Wall, Stardust Revolution, and Starlight Extinction. He also masters atomic destruction, teleportation, crystal manipulation, and the cloth repair technique. During the Pallas conflict in *Omega*, Kiki continued cloth repair operations at Sanctuary. He repelled an assassination attempt by the Pallasite Dione using Starlight Extinction. Later, he repaired cloths for multiple Bronze Saints, addressing their doubts about cloth functionality. He joined other Gold Saints in escorting Athena to Pallasbelda, defended repair outposts against Dione's forces, and contributed cosmic energy to breach the Gate of Time alongside fellow Saints. He later escorted Athena through Vanaheimr and participated in battles against Hyperion within Pallas Castle.
