Kororo

Kororo(コロロ, Corey in the English anime) is a Kuroppokkuru and the guardian ghost of Usui Horokeu, nicknamed Horohoro.

About
Kororo is a Koropokkuru (known as Minutians in the English anime) a tiny spirit people and the spirit ally of Horohoro. She is a nature spirit and can therefore, unlike human ghosts take a solid form without being placed inside a medium.She can also control cold on her own. She is later revealed to be a human girl who Horohoro fell in love with, who reciprocated his feelings, but Horohoro's father made him avoid and ignore her, unintentionally leading to her death when she tried to follow him to ask him why and she fell down the mountainside into a snowdrift. When the Koropokkuru came to guide her spirit into the Great Spirit once she died she refused to go and chose to become one of them, so that she could live and stay by Horohoros side and one day find the real reason why he ignored her as she knew he loved her. When Horohoro finally finds out her identity she explains and tells her story and finally promises to stay by his side forever. People who meet her are often smitten by her cuteness. Her people the Koropokkuru are in danger of being wiped out because there are almost no more Butterburs/Fuki left for them to inhabit. Though Horohoro initially blamed himself for her death and threw both his name, identity and soul away he later takes them back once she forgives him. She is the main reason for Horohoro's participation in the Shaman fight as his dream is to apologize to her and create a vast field of Fuki which she loved so much.

Past
Kororo was once a human girl, born Kurobe Tamiko, but nicknamed Damuko, whose family moved to Hokkaido because her father had a building project, constructing a dam that would destroy everything in the area around it, something that led her to be shunned. In her school she tried to befriend a boy named Usui Horokeu, even giving him the nickname of Horohoro, because the nickname "Usui-Kun" did not sound good and because "Horokeu" was hard to pronounce. At first Horohoro rejected her, but as she explained that she wanted to befriend him because they were alike(both of them were lonely) they became friends. However because of her father's dam, the Ainu Tribe Elder forbade Horohoro to see her, in turn leading him to not talking to Damuko.

Half a year later Damuko asked Horohoro why he ignored her, even wanting to hold their promise of seeing the Fuki fields in the spring. But following him into the mountains she had an accident and eventually froze to death. There the Koropokkuru tried to guide her soul to the afterlife but she refused, wanting to know the reason why Horohoro ignored her. There, Gororo appeared saying that the only way to stay on this plane was to become a nature spirit like them, and protect the lands and its people, which Damuko accepted.

Invading the Plants
While Horohoro fought with Kalim of the Ten Patch Officiants, Kalim called Horohoro by his real name and trying to make him reveal his true self. Horohoro would in his anger reveal the events that happened between him and Damuko something that made Kororo take her true form as Damuko and reveal to Horohoro how she became a Koropokkuru. She also explained that Gororo told her that once becoming a Koropokkuru she would stay in that form until her master's "Ice Thawed" where she return to her true form once. As she turned back to her original form, Horohoro hugged and apologized to her.
