Main characters

Shotaro (将太郎, Shōtarō)

Voiced by: Mayumi Tanaka (drama CD)

A young Dokeshi known as the "Kyokotsu", Shotaro's power allows him to mimic the abilities of animals by biting animal bones (e.g. the bone of a bird will give him the power of flight) with his condition to use his power being that he must do one good deed every day or he'll lose something "precious" inside of him. Childish and simple-minded, he's an avid fan of the "Charisma Justice" TV show and even copies the main character's "Justice Blade" attack, but has trouble remembering that it comes on every Sunday at 10:30. It is later revealed that Shotaro can draw power from any bone, and even call upon the memories and personality of the deceased. He greatly values his friendship with Emine and thus diligently performs his good deeds. Even though normal people hate and despise Dokeshi, he holds nothing against them.

Mana (真夏)

Voiced by: Saeko Chiba (drama CD)

A 16-year-old human girl who accompanies Shotaro on his journey to find his missing friend, Emine. She's constantly entering contests in order to get money. Originally from China, Mana is a highly skilled martial artist and is even capable of fighting on par with Dokeshi. Her fighting style is called "Hinoki-Ryu" and is only taught within her family. However, due her father's preference for her brother, Mana was neglected. She likes fortune telling, as it helps her make decisions, but she absolutely hates it whenever someone calls her "Garbage" as her name spelled backward in Japanese "Anam" means "Raw"; essentially making her "Raw Garbage".

Tool (トゥール, Tūru)

Voiced by: Yūji Ueda (drama CD)

A kappa who loves kiwis (a pun, as the Japanese words for "cucumber" and "kiwi" sound alike), he possesses the unique ability to hear the emotions of people and objects. He normally lives in a garbage dump, but occasionally visits the city to buy kiwis. He hates most humans because he thinks they judge others based on appearance alone. He also has a complex when it comes to his lack of hair, flying into a violent rage and chasing down anyone who dares call him a "baldy", as Shotaro found out the hard way. His primary weapon is a giant pickaxe he can swing around using a length of rope attached to the end, all of his attacks are named after different kinds of snakes. As a Kappa, he also has the power to rip out souls, but unlike normal Kappa, Tool can only use this ability on inanimate objects.

A Dokeshi known as "Bai Ze" and Shotaro's childhood friend whom he's been desperately searching for all this time. Emine's power allows him to manipulate his blood and shape it into various demonic weapons, his condition is that he must perform one wicked deed every single day or he'll lose his treasured friendship with Shotaro. Despite still caring for Shotaro and their friendship, Emine believes the nature of their respective conditions makes it impossible for them to get along.

Known as the "King of Spin", Nofix has the power to manipulate rotational energy, allowing him to stop bullets by spinning them in the opposite direction and enhancing his body's natural healing process by spinning his own cells among other things. His daily condition is unknown as he's never shown doing or speaking about it. Besides his crazy and bloodthirsty nature, Nofix's also completely and utterly obsessed with Yohei, having a sexual (and perhaps even romantic) attraction to him, so much so that he's vowed to murder anyone and everyone who he associates with.

Zuno (ズーノ, Zūno)

A Dokeshi with long nose hairs, Zuno is the chief of the Fear Factory's Intelligence Division. His power enables him to use his nose hairs to pick up electromagnetic waves, allowing him to listen in on target from afar. His condition erases a recent memory of his whenever he utilizes his ability and, as a result, he cannot lead a normal life or even remember his assignments without help from his assistant, Assi. Despite being employed by the Fear Factory, Zuno is not a bad person and, according to Assi, he only joined the Factory because his condition prevents him from working at a normal company.

Assi (アッシー, Asshī)

A normal human with strange glasses that have the letter "A" engraved on the lenses, his job is to help Zuno remember things. Much like his boss, Assi's not a bad person and only works for the Fear Factory because his lack of intelligence prevents him from doing anything else.

Solence (ソレンス, Sorensu)

Other characters

Charisma Justice (カリスマジャスティス, Karisuma Jasutisu)

Two Dokeshi brothers with the same ability and condition: to manipulate the water content of their body, which allows them to change shape as well as attack with water; afterwards, they must eat dried food.
