A friend of Asaga's who was always sickly with a hereditary disease. As he stayed sick he grew angry with the outside world, he went to Psyren and offered Asaga a card but he refused. In Psyren, he is a figure wearing, holding a rifle that uses his PSI energy. After he kills all but the five survivors, he takes aim at them and destroys part of the building. Amamiya says he's a Burst user and he also uses Rise to fight her physically. After using Trance, Amamiya realizes that Tatsuo was transformed into a Tavoo by having an orb implanted into him. Tatsuo regains his mind after being hit by Ageha's, however his core remains because it is integrated to his body. Because he does not have his card, he stays in Psyren, revealing that he will die when his core runs out of energy, but will look for a way around this. He describes his time as a Taboo as being trapped in someone else's body, and regrets all the killing he did. He appears later on chapter 69 when he saved Asaga from some Taboo. He is later shown with a new Asaga as they are planning to take down a tower. Tatsuo appears again during the W.I.S.E attack on Tenju's Root, riding atop Hiryu's dragon PSI. He uses his gun to poke holes in the dark sky, revealing the sun and causing the Tavoo in the area to disintegrate. (Wikipedia)
A young girl traveling around collecting commendations. She goes where fortune tellers tell her to go. Shotaro is her first friend. She was born in the Chugoku, the land of martial arts. She practices Hinoki Ryu. As a child, she was weak and lonely. She eventually decided to cheer up.
Mana Tsuburaya is a second-year Coppelion, all of whom are considered defective since they constantly emit neutrons, making Mana and her peers into walking biohazards that waste living beings through their mere presence, except for other Coppelion. As one of the most powerful Coppelion, Mana can wield a wide variety of special abilities mostly revolving around psychokinesis and the control of gravity, such as the ability of flight (which she's using almost constantly to move), levitating other objects, stopping bullets, and creating violent shockblasts. Mana is working under Dr. Coppelius against Ibara and the others because he promised that he'll find a way to fix her defect. Alongside her best friend Meisa, she is a former member of Exploration Unit that went renegade just like the Ozu sisters. Mana's most notable personality trait is her being very quiet and stoic, initially to the point of appearing eerie to her adversaries. After her introduction in volume 10 she couldn't be seen uttering a single word until a volume later.
In order to balance the immense positive magic of the Clow Cards, Clow Reed created the Nothing Card (ç„¡), containing negative magic equivalent in magnitude to the other fifty-two cards. Anything that comes into contact with it will cease to exist. Nothing appears in the second movie and is terribly lonely in the beginning, unable to interact with others without destroying them. The only beings that can interact with her safely are the other Clow Cards. As a result, Nothing tries to steal the Clow Cards (now Sakura Cards) so that she would not be alone again. Nothing's presence is vastly encompassing, once detecting Eriol's attempt to call Sakura about the card and destroying the phone lines as a result. Nothing continues to steal the Sakura Cards and destroys everyone and everything that Sakura holds dear; Nothing likely views Sakura as a villain who stole her "friends" (the Clow Cards) and intends for Sakura to suffer the same pain of loss that it has felt for centuries. In the end, the Sakura Cards try to return to Sakura, and Nothing falls into hysterical despair, believing that her friends have abandoned her. However, Sakura convinces Nothing that it can be her friend, too, together with all the Cards. She returns Nothing to a Clow Card form and then transforms it into a Sakura Card by merging it with the Nameless card to form The Hope. All the damage and deaths caused by Nothing are then miraculously undone. Nothing is composed of a spherical force field of emptiness where nothing exists. In the center of this force field, one could make out a young girl with long, silvery hair wearing a frilled dress. There is a constant expression of sorrow on the girl's face. When captured and changed into a Sakura Card, she is clasping the winged heart that was the Nameless card and has, for the first time, a smile upon her face. Wikipedia entry
