; : In his final year in middle school, Kakeru feels his life is a little mediocre. That is until he meets the other Psychics and has his life changed drastically. Kakeru's has a power known as, Chronodiving (though he is initially ignorant of it), so he is commonly referred to as a Category 0, the Chronodiver. Chronodiving allows him to jump through time. But, each time he goes back in time he causes a rift in time. His abilities are not explained until the 4th volume, where Takemaru proposes that Kakeru could turn back time. He seems to really care for his friends even risking his own life to save them especially Ayano. He is in love with Ayano and has tried to ask her out, but she refused due to her misunderstanding of the term going out (Maya tells her going out means doing
ecchi things). ; : The leader of the group, his power is that of
Clairvoyance, the ability to see the future. He wishes to prevent a vision he saw showing the end of the world. It seems as though the use of this power takes a great toll on his energy levels, causing him to go into hibernation after major usage of his ability. : It is revealed that he and Ikushima are more closely related than anybody has thought. ; : The only girl in the group, her abilities include
Telepathy and
Astral Projection, which together allow her to temporarily possess someone. She wishes to experience life like a normal girl would and attend school, which she’s never done before. It seems that she develops feelings for Kakeru when she gets so irritated and jealous seeing Kakeru so close with a girl but she doesn't realize what she is feeling. Later on she realizes that she really is in love with Kakeru. In chapter 20, she accepts Kakeru's confession. ; : Xiao Long is the smallest of the group. His abilities include Healing and
Qigong. Qigong is actually a Chinese breathing exercise, but it is commonly perceived as a way to channel one's "qi" (also known as "chi" and "ki") into an active force (e.g. Palm blasts) in pop-culture. He blames himself for his parents' death for they died arguing over the money they had charged people to have Xiao Long heal them. ; : The group's "tough guy", although he cares a great deal for his friends. Kaito's power is
Pyrokinesis. He has a tendency to get slightly carried away. ; : A teacher at Kakeru's middle school, she temporarily looks after Joi while he recovers and uses the school as a safe house for the group. : Later, she is also revealed to be an agent, codenamed , of a secret government agency known as . ; : A first level manager of the Greenhouse. His powers are
Clairvoyance, as well as the ability to create false futures (which can conflict with Joi's powers), and inflicting rapid cell growth, which turns the opponent into an aged body within seconds. He has been given the job of retrieving Joi at all costs, even if it means killing the other Psychics. He was the cause of the apocalypse in Joi's vision. ; : A Psychic working with the Greenhouse to retrieve Joi. Her power is
Illusion. Her power is significant in that the illusions can harm those trapped within them. In volume 4, she disguised herself as a high school girl pretending to have crush on Kakeru, however, she eventually falls in love with him for real and reveals herself as Maya only to Kakeru. ; : A Psychic also working with the Greenhouse to retrieve Joi. His power is
Teleportation. He uses throwing knives as weapons. In the Japanese version, he speaks in a combination of Japanese and English. ; : Extremely powerful, Takemaru's power is
Psychokinesis. He is well known for being unstable and violent. He used to be bullied constantly when he was young because he was short while his name was fierce. He caused the deaths of three bullies after they burnt his eye. He uses his power to levitate pencils and use them as projectiles which are as powerful as bullets. After Kakeru saved him when the school gym collapsed and offered to become his friend in volume 2, Takemaru "disappeared" then turned up again in volume 4 of the manga to save Kakeru from an attack from the Greenhouse. ; : Another Category 0. He is a clone of Kakeru. Like Kakeru, he has the power to stop time and change the past. Due to his power having awakened much earlier than Kakeru's had, he has much better control of his power than Kakeru and is therefore more skilled of the two. In fact, at first, he seemed to be immune to Kakeru's time-stopping power. : His hatred towards society and especially Kakeru, as well as his adoration for Ikushima, which grew out of his gratitude for Ikushima being the first person to acknowledge his existence was the cause of his murder, by Ikushima's hands. ; : She has the ability to call supernatural beings, Gigantes, from the dead. These beings can be massive, but are vulnerable against Xiao Long's qigong. ; : Arata Ikushima's daughter. She died in an accident on the bus seat next to Kakeru. However, Kakeru has no recollection of her, nor of the accident. She appears in the Tower of Time teaching Kakeru about his powers. ; : Kaito's younger sister, who appears to be blind and wears a kimono in the Tower of Time. She died to protect Kaito when he was badly beaten by a group of people. ==Reception==
