Usui, Horokeu

Horohoro is an Ainu from Hokkaidou, a prefecture in Japan. In the English anime, he is described as from "the Northern Woods" instead of from Hokkaido. Horohoro's main goal in the Shaman Fight is to save the Koro Pokkuru ("Minutians" in the English anime), a tiny spirit people. As part of this goal, he intends to plant a vast field of Butterbur. His guardian ghost is Kororo ("Corey" in the English anime), a spirit who is smitten with Manta Oyamada. Also in the manga, he becomes the third strongest of the Five Elemental Warriors and gains the Spirit of Rain. His furyoku is 120,000 (as seen in chapter 276). This, oddly, makes him "technically" stronger than both Yoh and Tao Ren, who have more importance in the series than him, who only have 108,000 and 100,001 furyoku respectively.

Horohoro is good-natured and cheerful, but he gets serious in dangerous situations. He argues constantly with his teammate Tao Ren, and they do not seem to get along at all. However, it is shown that he really does care for him when, in the manga, he tells You Asakura that if he can't save Ren, as his friend, HoroHoro would never forgive him. Horohoro is also very secretive about his past not willing to talk about it even to his friends. In addition, Horohoro can also get very competitive, even going so far as to turn Ryuu's arms to ice and shatter them during the fight between The Ren and Funbari Onsen. Horohoro's name sounds and is spelled (in Katakana) like "boroboro," which means "crap." Characters mispronouncing/misspelling his name is a running gag in the series. It's later reveled that Horohoro's real name is Usui Horokeu.

In Shaman King: Kang Zeng Bang,

[Spoiler] Invading plants, he got furious by Kalim mentioning his true name. He claimed that he threw that name because that was the named that killed the girl he loved. It was revealed that Damuko, Horohoro's childhood friend and crush, was actually Kororo. [/Spoiler]
