He goes by the nickname Meruka Kuramitsu (倉密 メルカ, Kuramitsu Meruka?). Dissatisfied with the prospect of a regular and unexpressive life that he can predict with 100% accuracy, he works as a for hire bomber and is famous for his ability of escaping from his captors. He is fourteen years old when he chooses a nickname based on a comic character he liked as his alias.
He refers to both his adult self and his young self as a robot that simply idles by life following common instructions. However his pessimistic behavior is usually counterbalanced by Mana's curious and cheerful disposition, and she usually requires so much attention that Mitsuru doesn't really have the time to feel down.
Kara no Kyoukai: Future GospelEdit
In 1998, during the Möbius Ring chapter, a 14 year old Kamekura takes an interest in Shiki Ryougi when she saw his face and recognized him as the bomber right after he fulfilled a job. At that point he noted that he must take her out to protect himself, and began to pursue and set traps for Shiki. However, she easily escaped from all his traps and he is trapped by Shiki, who overpowers his ability with her Mystic Eyes of Death Perception and permanently damages his right eye, sealing off his precognition abilities for good.
Because Shiki correctly noted that Mitsuru needed to "pave the path" of the present using what he saw with his left eye in order to achieve the logical result that would be shown in his right eye, and thus what he sees is not the future per se, she is able to defeat him. As the "prediction" could actually be killed, it would destroy the "certain factor" of his calculations. When Shiki destroys his right eye, Kamekura is unable to make accurate predictions and encounters unknown unforeseen events; the detonation of the bomb he set up is delayed by five minutes, and he is defeated.
In Möbius Link, 10 years after his defeat in the hands of Shiki, he is close to 25 years old and works for Mikiya Kokutou's agency while keeping his main job of being an author of children's stories. He owed Shiki's criminal syndicate a huge financial debt in a twist of fate and got this current job to repay this debt, thanks to Shiki's mercy. His work for Mikiya usually involves doing background checks and sometimes he will be requested to partake act on proper investigations. Occasionally, Mana Ryougi usually kills time reading books or speaking with him in his office; Kamekura will grudgingly acknowledge that Mana is his savior, as she recommended him to the agency when he was in extremely bad economical shape, forgiving his many debts to the syndicate.
Mitsuru is a professional bomber hired by individuals mostly for the destruction of property, as none have brought forth enough money for murder. He does everything from the bomb warnings to the actual deed. He works with explosives mostly suited to the destruction of buildings and construction sites, so they would require certain preparations if they were meant to take a life. He works on lesser jobs that are more showy than destructive using tools like incendiary bombs made from a mix of aluminium powder and iron oxide and chemical explosives made from fertilizers and engine oil. The bombs, while capable producing enough explosive force to kill a person, are more comparable to fireworks, props meant to fool and incite people and accomplish his job. He then blends into the fleeing crowd of people to escape, best making use of his precognition to always avoid capture. The preference for explosives is due to them being the best equipment with which to make best use of his Precognition.
His first three explosives against Shiki include a flashbang-like explosive at a construction site, an incendiary landmine planted on a road near Ahnenerbe, and a timed alarm clock-bomb, for demolition purposes, placed in the ruins of a purposeless abandoned building. They are all empty areas, so she is able to escape unscathed. Though she decides to enter the empty building on a whim, his precognition allows for him to foresee ahead of time to place the bomb and have it hit zero just as she enters. The fourth is an incendiary bomb hidden in a parked truck on a bridge, but she is able to avoid the large-scale destruction at the last second by jumping into the river. That is in line with what he has predicted, so he moves to his final plan. As his precognition is a matter of inevitability matched with reality rather than probability, he believes his final bombs will kill her.
His final explosives meant to kill Shiki consist of three metal pipes on the roofs of parked cars inside a parking garage, activated by a switch that sets off an unassuming, simple fuse. It is a three-point trap meant to cage her in the most efficient way and certainly kill her. The location is chosen for its low ceiling and poor line of sight due to being filled with columns, cars, and other obstacles. Each pipe is packed with a large enough concentration of gunpowder to require both ends be sealed and five hundred 2mm carborundum shrapnel. Differing from bombs meant for destruction, they are made specifically to kill Shiki, as the shrapnel will travel in all directions for ten meters with assurance that they will strike the target. There is no method of escape, and using the coming of a family to dull her senses momentarily, her fate is to have her bones ripped from her flesh. While the scenario was weighed together to keep anything like the signal having an issue, a malfunction with the remote, or a mismatch from happening, Shiki killing the future causes the gunpowder to refuse to detonate coincidentally until he tries again five minute later.
Mitsuru possesses Precognition in his right eye and the ability to achieve the future in his left eye. Able to foresee the future like watching a film, he right eye is able to see something like the ideal score on a test five minutes later, a day later, or even a month later. The left eye views the present and projects the methods by which the viewed result can be actualized like the method of achieving that ideal score. Like having a test’s answer sheet filled in before him, all the necessary measures for fulfilling the future are instantly projected in his left eye upon viewing it. If he acts according to the image, the film playing in his right eye becomes the unchangeable future. He doesn't view it as the future, but rather the "obvious result" created from the accumulation of the present, causing a variety of emotional issues for him.
While reality cannot be determined by formulas because it is a fluctuating value unable to be determined until the answer is obtained, he is able to fix the value beforehand to make the answer unshakable. Weighing together the variables called reality, he actualizes the "successful future" at the cost of his own free will. Ignoring "wishful observations" like his own interests and emotions, he views himself as a slave for the purpose of bringing about the determined future. When given a job like destroying a floor of a hotel with no casualties, he wishes for the result, sees the hotel wrapped around by black smoke, and simply acts on the vision. He can even see variables like the resulting casualties and property damage. While the method by which the future is achieved may slightly differ, such as someone taking a different path or people arriving slightly later, the overall scenario will play out according to his wishes. The only time it completely fails is upon meeting Shiki and having not seen her name with his right eye that day. It is the first time his right eye has failed in such a way, bringing about his obsession of wondering if he is able to kill her.
One main difference from predicting the future is that he must be actively watching the location of the future in order to bring it to absolute completion. He cannot be an indirect third party if he is to weigh all the variables together. Even if he can measure the factors of reality and understand the result, he has to see "that instant" himself because it is the future seen with his own view. His first three attempts at Shiki's life fail because he only sees "a future where he placed explosives in a place he lured Ryougi Shiki to", when the absolute condition of having her dead would require him to see a vision of her dead body. This puts him at a disadvantage when the target knows about him because it is known he is located in their line of sight. He can see multiple possible outcomes when not fully present at the site, allowing him to plan contingency futures based on the different outcomes.
The ability, calculation of the future, differs from and exceeds prediction of the future. The future is normally uncertain and unable to be reached out to because it is not there, and prediction only allows for seeing a possibility of a future that may eventually occur. Calculation is an abnormal ability able to determine an outcome through his own will which will definitely occur. This proves to be a weakness against the Mystic Eyes of Death Perception, as they would have been unable to kill an uncertain prediction. He cannot reach out to a coincidence, so he gives the invincible future form with his eye. Reaching out to a certainty gives it a clear form, but that also means it is able to become broken. It is no longer unknown after having been determined, so with it having form, the concept of death applies to it even more so than the invisible, twisting spirals created by Fujino Asagami. The future is bisected and extinguished, causing his perfectly set-up bombs to temporarily malfunction without reason. His right eye, also feeling as if had been bisected, loses its light, and the ability to see paths in his left eye is unable to see a fragment "a future where escape is possible."
