Characters

 * You Keika (Chinese: 杨敬华, pinyin: Yang Jinghua)
 * (Japanese), Li Lanling (Chinese)
 * He is the heir of an old and famous exorcist. He is a direct descendant of You Nei and is able to wield the sword Rakugetsu. Ever since his parents died, he lived a life of poverty. Soon after, he worked part-time as a fortune teller and computer recovery to make money. One night, in the junkyard he meets Tanmoku-ki fighting an evil spirit. After their meeting, he unfortunately died in an accident and became a spirit. Soon after, he is asked by Tanmoku-ki to form a "pact" with him. You Keika becomes a spirit shadow of Tanmoku-ki.
 * He is a carefree character, but is quite emotional at times. Initially very weak and unable to fight, he gains power later in the series, and is called The Most Powerful Spirit Shadow. Once he learns more about Ki, he proclaims his loyalty and resolves to protect Ki at all costs.


 * Tanmoku Ki (Chinese: 端木熙, pinyin: Duanmu Xi)
 * (Japanese), Liu Mingyue (Chinese)
 * He is the 13th Youmeshi and head of the Tanmoki, the most powerful exorcist family and a descendant of Tanmoku Rakugetsu. Being an illegitimate child, he is called in by the main family after his parents died. He formed a "pact" with You Keika. He always protects You Keika from people, going so far as to pass an order that no one is to punish Keika, even if he kills him. He also gives Rakugetsu (the sword) to Keika. His fiancée is Shin Shiyou.


 * Immediately after Keika's death, he saw Rakugetsu's spirit emerge and makes a bet with him that if he prevents Keika's soul from breaking for a year, then Rakugetsu will stop.


 * Ki has a rather cold personality with all the people around him, including his grandmother, who is his only ally in the household and even his fiance; but strangely, he cares very much about Keika. He has very strong spiritual power. To keep this body pure from impurities, he doesn't partake meat, and also keeps himself free from wounds, as he can't have blood transfusions even if he is severely injured. As a child, he had gotten a scratch from Rakugetsu, which sealed off a little of his power, but he gets it all back when Rakugetsu is finally sheathed. He even has to wear an earring so that his overwhelming power is controlled.


 * Shin Shiyou (Chinese: 秦詩瑤, pinyin: Qin Siyao)
 * A spiritualist and a holder of Nenyou constitution. Shiyou was chosen as the fiancée of Tanmoku Ki due to her powers that can heal the Youmeishi. Knowing that the spirit shadow will have a close relationship with his master, she is jealous of Keika, as Ki is always cold towards her. Even so, she trusts Keika and calls him the strongest spirit shadow. She is fiercely loyal to Ki, supports him and understands that he toils with his position.
