The fictional universe of the Japanese manga series Blame! is home to many characters and locations, created by Tsutomu Nihei.
Main characters
Killy is a main character of Blame!. He is a cyborg tasked by the governing AI agency with finding a human in the 5.3-AU radius Megastructure who still possesses the Net Terminal Gene, a genetic marker necessary for safe access to the Netsphere, from which the functions of the Megastructure may be controlled. He is equipped with a Gravitational Beam Emitter (GBE), a compact but immensely powerful weapon capable of creating holes miles long in the Megastructure. He is soon joined by Cibo in his quest. Looking to be in his early to mid-20s, he is a glum-looking person, never smiling (except madly when shooting on occasion) and has a slight slouch in his normal standing position, he is not afraid to fight, and readily shoots the GBE. He also often shows superhuman strength and endurance, being thrown through solid walls and floors before standing right back up with no apparent injuries. The GBE is so powerful that he is flung backwards by its sheer power, often into walls and the ground, but he always gets up. Even in its lowest power, his arm jerks up and back from the force of it. During the encounter with the giant Safeguard outside Toha Heavy Industries, he fires at the Safeguard with the GBE at Level 4 Extra power level. The recoil from the GBE is so powerful that he is thrown back a considerable distance and his right arm is broken, exposing bone and tissue. Killy can survive injuries that would kill an average human as well as recover faster. In the times when he is quiet, he injects drugs into himself in the forehead, and when he is low on power, he may inject it straight into his hand. He has an electronic connector to create signals to stop Builders and to transmit information from one person to himself, and vice versa. He also has no memory of his past, or how he obtained the GBE. Killy distrusts Silicon Creatures on sight, and destroys them whenever possible; whether or not they are hostile towards him or his objectives does not bear any weight on his judgement. In Blame!², however, he rescues Pcell (part of a new, relatively peaceful generation of Silicon Life) from the Safeguard, indicating either that his priorities have changed or that he no longer considers Silicon Creatures to be a serious threat.
(anime film), Asuka Aizawa (Japanese, ONA) Cibo is the head scientist of the Bio-Electric Corporation in the Capitol and joins Killy on his quest for the Net Terminal Gene. Killy's first encounter with Cibo is in the lower levels of the Corporation in The Capitol, where she has been imprisoned for attempting to access the Net Sphere with an artificially created version of Net Terminal Genes. Her failed attempt to access the Net Sphere led to the appearance of the Safeguard, which destroyed the entire lab facility that Cibo was conducting the experiment in. The death and destruction resulting from Cibo's failed experiment led the governing body of the Corporation to convict and imprison her. Cibo's first form is the decaying upper torso of a woman kept alive by machinery inserted into her body. She convinces Killy to take her with him by stating that he needs her hacking skills to access the files he is looking for. Afterwards, she transfers her mind to a replacement body and aids Killy in destroying the Corporation's President. Following that, Cibo leaves the Corporation to travel with Killy. Later in the manga, Cibo's physical body is killed by the Safeguard, but her mind takes over Sanakan's body. However, Sanakan's consciousness still remains in the body, forcing the two women to share it. Cibo is able to suppress Sanakan's mind, preventing it from gaining control, although on one occasion the Safeguard managed to take over. After the encounter with the Silicon Life, Mensab and Seu, Killy is teleported to an alternate reality, where he meets an alternate Cibo in her old form. Both versions of Cibo face one another and wish to return to the original reality. During the attempt, the alternate Cibo is killed by a Silicon Life creature, while the original Cibo is severely damaged and Sanakan's mind uses the opportunity to resurface. At the last moment before she is overtaken, Cibo extracts her personality data and transfers it into the corpse of her alternate self, reviving the body and living again. After an altercation with Silicon Life intending to access the Netsphere, a Level 9 Safeguard (the highest level) was illegally downloaded into Cibo, resulting in her ultimate transformation into the Level 9 Safeguard and the newly-bred Net Terminal Gene. The sphere that she stores in her lower abdomen carries the gene that can save the city if it is taken to its very edge where it can grow uncontaminated by the megastructure and its inhabitants. Sanakan mentions that the "child" is a product of hers and Cibo's combined DNA. Cibo is heavily weakened by Killy's GBE shortly after her transformation, reverting to a childlike state and eventually falling into the hands of the Silicon Creatures despite Sanakan's efforts to find and protect her. Sanakan asks for a return to the Base Reality without backup data, driven by a desire to protect her "child" and charge. She tears through Silicon Creatures to reach Cibo, and then encounters a First Class Exterminator. Killy destroys the Exterminator and recovers the orb, though the Exterminator destroys Cibo and Sanakan during the battle.
Other characters
Safeguard The Safeguard are a program independent of the Netsphere. The Netsphere was designed as a means of providing service to those who could log on. However, the Netsphere was thrown into chaos (the actual reason is not exactly known, but the prequel manga NOiSE implies that a small group of humans is at fault) and the Safeguard changed their modus operandi from preventing unauthorized users from entering the Netsphere to killing off anyone who does not possess Net Terminal Genes. The Safeguard have nine levels of hierarchy, Level 9 being the most powerful. However, their Exterminator (originally the lowest level safeguard) system has a different form of hierarchy where "First Class" is the most powerful.
Sanakan is first seen as a short, young girl with black hair who finds Killy and Cibo in a tunnel after they pierce the impenetrable Megastructure layer with the GBE. Killy later discovers her true nature and she reveals herself as a high-level Safeguard with a GBE similar to Killy's. At first, Sanakan behaves like any Safeguard intent on annihilating all humans without the Net Terminal Gene. This changes however, when she becomes a representative of the Governing Agency with the task of retrieving Cibo, who at that time becomes the illegal level 9 Safeguard unit. At this point, she adapts a more protective role. Sanakan's physical body was destroyed twice in the line of duty; First in order to destroy the Toha Heavy Industries' Central AI and for the second time while protecting Cibo from Silicon Creatures. She finally dies when she sacrifices herself in order to save Killy and the globe that Cibo carried from an Exterminator. Sanakan has been the second "mother" of the child with the net terminal genes, along with Cibo, who was carrying the globe with the embryo.
Dhomochevsky - Dhomochevsky is a Special Safeguard; the type that is not hostile to humans. This may be due to the fact that he and Iko were essentially stranded in base reality with no backup when the safeguard system on their level was disabled by silicon creatures shortly after their programs were initiated. He has a distinctive scar on his left eye where Schiff stabbed him. Along with Iko, he was recruited to protect a provisional level of the megastructure. A group of Silicon Life cyborgs has invaded this level, led by Davine. Dhomo and Iko are insistent on the level's defense because only normal human genes are required for access to the netsphere. He is armed with a quad-barrel gun with many different projectile types. Dhomochevsky is heavily damaged and decapitated by the newly downloaded Level 9 Safeguard, which was instinctively responding to a threat. Iko - Iko appears as the thin, white wisp of a facial image. However, in the manga, it is suggested in a flashback of Dhomochevsky's that she had a corporeal shape once, but how she lost it was never explained. Most likely, she was unable to gain a new body as the Silicon Life on her level captured the Substance Conversion Tower on which she and Dhomochevsky depended. She acts as a guardian for Dhomochevsky, predicts the behavior of his opponents, and heals him if possible. She transfers all her power to Dhomochevsky in a last-ditch effort to stop Davine as well as Cibo's transformation into a Level 9 Safeguard.
Silicon Life (Cyborgs) Ivy - Ivy is the leader of the contingent of Cyborgs attacking Toha Heavy Industries. He carries a massive weapon, which is essentially four swords, with two of them spring-loaded to swing out from the middle to bludgeon enemies. He is eventually defeated in a sword fight with Seu. (There has been some confusion as to which characters the names Ivy and Maeve are assigned to. This is most likely due to the artwork of the two characters reading: Ivy & Maeve, with the more feminine cyborg on the left and the other on the right. Apart from the text, the artwork is in original Japanese format, and in Japan, they read right to left. Also, in volume 4 their names are clearly distinguished by their dialogues.) Maeve - Maeve is Ivy's sidekick. The lower half of her body is sliced off by Seu in a fight. Later on, Ivy and some of his contingent discover the 'advanced' cyborg fused to a wall. They cut it out, wrench the cyborg's original head out and implant Maeve into the body. Later, as Maeve is about to execute Mensab, Seu attempts to kill her by throwing his sword and lodging it in her forehead. She seems almost indifferent to this, but before proceeding, she is killed by Killy who fires a Gravitational Beam through her heart. This happens just before the teleportation of Toha Heavy Industries. Blon - One of Davine Lu Linvega's henchmen. Blon is capable of commanding worm-like creatures, which attach to a target's spine and render the target unconscious. He has the capacity to transform his body, taking the shape of a large centipede-esque creature in his first appearance before morphing into a humanoid shape to attack Killy and Cibo. Most of his body is destroyed by Killy in their first encounter. His first defeat allows Pcell to detect the 70-kilometer long holes left by Killy's GBE. When Dhomochevsky, Cibo and Iko set out to find Killy and Davine, Pcell appears to confront them at a large Megastructure transport hatch and minutes later, Blon appears in his third form at her command. The third form resembles a large, metallic, spider-praying mantis hybrid with Blon's face and his large chain-gun (Vulcan Cannon/Gatling Gun) on its left arm (where it is in Blon's humanoid form). When Blon attacks, he slightly wounds Dhomochevsky and is able to steal a capsule from Cibo containing Seu's genetic information. Blon is finally killed when Dhomochevsky, Cibo and Iko enter the hatch's portal and close the hatch itself while Blon is still in the hatch locking area. This crushes and destroys his entire body. The capsule lands less than a foot outside the hatch radius and is picked up by Pcell.
