Hajime Damemaru

Hajime Damemaru (一＝ダメ丸, Hajime Damemaru) is an immortal man, chased by the Photosfere. He is accompanied by a package called Nagurun.

After escaping the asteroid of the Lighthead Order with Zaha Sanko and the others, he proposes becoming allies due to their common enemy. He is one of the "Hateful Four", the four most dangerous individuals to the Photosfere.

Appearance
Hajime looks like a tall man wearing a black garment with a face veil. He usually wears Nagurun as a backpack, but the package can cover his entire body like a set of armor with a chitinous appearance. Initially, his face was obscured by his skin being ripped off and suffering from multiple gunshot wounds. He also had sharp teeth. After being torn apart by an explosive, and during the events of chapter 11 to 15 he was a merely a head connected to some guts, showing the extent of his immortality.

After his recovery in chapter 16, Damemaru has short black hair, bushy eyebrows, bags under his eyes, a chin beard and the beginning of a goatee.

Personality
Hajime Damemaru is a self-proclaimed sixteen year old teenager; however Shimada mentions his Age Discovery ability doesnt register a number for his age, possibly implying he is much older. He is generally polite and forthcoming, shown in his interaction with the doctor in chapter 9, and with showing Avakian (who initially told him to "get lost") the control room in chapter 15. Besides that, he is smart and calculating, opting to not fight Shimada and Avakian, as he dislikes fighting battles with low prospects.

He also shows a ruthless and dangerous side, immediately controlling Sanko's mind when touched by him, trashing Sanko's body to fight against the Photosfere cleaners and killing them with his bare hands. Sanko was left heavily injured due to this and eventually captured by the Lighthead Order. He is proficient in technology and was able to mod Nagurun. Unlike the familiar relationship between Sanko and Avakian, Nagurun seems to obey his commands without a will of their own; however Damemaru tells Sanko that although Avakian and Nagurun may be different, he still considers his Packadge as his only true friend.

He dislikes his first name, "Damemaru", which translates into "totally hopeless", and hates that no matter what he does or where he goes, people keep refering to him as such even if they have no way of knowing his name - changing his name is one of his greatest wishes. Damemaru uses the masculine personal pronoun ore (俺) to refer to himself.

Plot
On the hospital planet Klinik, Hajime Damemaru enters one of the hospitals and seeks a doctor. He is asked to state his true name and explain the help he needs and he states he has fractured bones, gunshots, and internal ruptured organs. As he is welcomed by a doctor, he shows his gunshots and broken bones with the doctor commenting he is in a dreadful state and needs a better doctor. Hajime explains that he is chased and can't get to a decent doctor and decided to come here on purpose. As Hajime pays, the doctor gives him a special Medical Light device, with mysterious technology from Photosfere, that can heal any injuries. Hajime finds it funny that he is chased by Photosfere, but will be saved by their medicine. As the doctor gives him the device and wants to measure his pulse, Hajime realizes he is scared, explaining he has peculiar power that can tell him that. The doctor explains he gets nervous when he sells this device as he isn't supposed to have it and puts his life in danger. As Hajime leaves, Photosfere soldiers appear behind the doctor, who tells them he did as he was instructed.

He gets put on a ship that heads towards the headquarters of Photosfere. On its way Zaha Sanko, Shimada Death and Avakian board it and find Hajime mangled to pieces, but still alive. They are surprised someone like him can exist and Zaha suggests they may sell him due to being unusual, but as he removes a tube form him, the alarm goes off. Hajime then uses his ability, causing Zaha to lose control and attack the soldiers that came, killing as many as he can. Having no choice, Shimada uses his ability to kill Hajime, which makes Zaha come to his senses, but as they keep Hajime's corpse, Shimada notices him staring at them.

Abilities
Regenerative Immortality: Hajime can regenerate from any injury and is thus unkillable, but particularly serious injuries take longer to recover from. Even Shimada's Instant Death ability could only kill him temporarily, though when he threatens Damemaru with atomization he reacts with fear, implying the absolute destruction of his body might be able to kill him permanently. Photosfere has a device that can also halt his regeneration though not fully kill him, but the specifics of it have not been mentioned.

Adaptability: Hajime can adapt his body to any environment, though the adaptation seems to be slow for extreme environments, shown when he was initially crushed by the Dark-like environment inside Moja, which destroys any non-native creature. After a few days aboard the ship, Hajime's Package turned a dark color and he regenerated fully, now seemingly acclimated. Shimada mentions how he has become more resilient to death.

Mind Control : Hajime can use eye contact to influence other people's minds to their commands, which caused Zaha to lose control when he tried to take Hajime off the tubes and saw Hajime's eyes. However, he can't use this power if he can't see his target, such as in complete darkness.

Technology skills : Hajime has created many useful inventions that he takes pride in, such as the package Nagurun, the "Me-Me-Me Meal Machine" and "Sauce Sheets" with which the user is able to convert all sorts of sauces into sheets that are easy to carry in space, etc. Also he can invade ship systems to help him escape and gather intel with his inventions and is shown using Nagurun to hack machines.
