Rinku is a young demon who uses yo-yos to attack. Rinku is childish and playful, and often annoys those around him. He controls his yo-yos by channeling his aura through the strings. During the fight for control of the Makai, Rinku is one of the demons that Kurama trains to fight for Yomi, though they eventually all disband to fight individually in the Makai tournament. At the end of the manga, he becomes stricken with Sasuga, a female demon who defeated him in the Makai Tournament, and it is hinted that they are in a relationship together. In Volume 18 of the English manga his name is translated as Link.
