Rinichirō Hagire

Hagire Rinichirō a.k.a The Director was the main antagonist of the Deadman Wonderland series and the foster father of Shiro. He has researched the Wretched Egg for a long time, longer than his original lifespan. That is why he developed technology, used in combination with Chan and En's Branch of Sin, to overwrite his memories to another human being (his different forms are called generations), lengthening his own life. His ultimate goal was to recreate the Wretched Egg. His servants followed him generation after generation. Hagire modified them as well.

First generation
Hagire had a job as a researcher in the Medical Center ten years ago. He worked together with Ganta's mother, Sorae Igarashi. They were conducting research on how to heighten a person's immune system, and did experiments on several "guinea pigs", including Shiro. In the beginning, he wasn't interested at all, claiming he had 0% interest. Then, suddenly, Shiro's body began increasing the number of the Nameless Worm, to the point where so much of it was present in her body that it disassembled even the most potent anesthesia. As the experiments continued, he slowly gained more interest. To fuel this curiosity, he signed off on a number of inhumane experiments to promote the rapid multiplication of the Nameless Worm. A few of these include strapping Shiro to a cross and drilling into her arms, with no anesthesia (not that it would do any good). Later when she was complaining about her arms hurting, Ganta unwittingly told her, "Just call for Ace Man. He'll make all the pain disappear." In one experiment, while Ganta was still living with his mother at the lab, Shiro underwent a particularly excruciating test where she was dissected piece by piece while in a fully conscious state. She was introduced to so much pain in that single experiment, that she started to call for Ace Man. After her wounds had been stitched up, she kept calling for Ace Man, until she abruptly stopped. Sorae Igarashi noticed that she had stopped crying and looked over to see 'Shiro' giving her signature 'kishi' smile. This experiment caused the birth of the Wretched Egg.

At some point, during the experiments, Shiro's body started to regenerate, replacing large chunks of skin, muscle and bone simultaneously. This development caused Hagire's interest to pique at 100% where he posed the question, "Is this love?" Great Tokyo Earthquake was brought about when Shiro learned from Sorae Igarashi that if she used too much of her power she could kill herself. Wishing death sooner than the suffering she was being subjected to, she unleashed a large amount of her power in an attempt to kill herself. While doing this, she intentionally spared Sorae Igarashi, as she was one of the only consolation she had, but let Hagire fend for himself. Due to his extensive injuries, when he returned from the hospital, he set about securing a new body for himself. Using Chan and En's Branch of Sin, Hallow Swallow, he overwrote his memories in the body of the second Deadman Wonderland director, the old man, who was the strongest Deadman before Toto.

Second Generation
While in the body of his second generation, Hagire founded Deadman Wonderland with the purpose of searching for other Deadmen. He also started the Carnival Corpse to find the strongest Deadmen there is, as a target for his third generation. Shiro referred to him as 'Grandpa' in this form (though they obviously aren't actually related), and indeed, she lived with him for most of the time he spent in this body.

Original body
Hagire has long black, messy hair that is kept in a ponytail. He has a short goatee and wears glasses. He wears a white lab-coat over a black-and-white striped t-shirt and black trousers. He also has a necklace with four scalpels on it. In addition, he has dark circles under his eyes most likely due to sleep deprivation.

2nd Generation
He later takes the form of an old man. He had grey hair combed to the back, with scars on his body and face. He is dressed in hospital clothing, due to his illness. In the anime it has been implied that The Director is the father of Tamaki which most likely indicates that this host is Tamaki's father given the timeline and ages that have been shown throughout the series.

3rd Generation
His third and final form is that of Toto Sakigami.

Personality
Hagire is a mad scientist, sadist, and sociopath. He enjoyed experimenting on Shiro for her Wretched Egg persona. He claimed his interest in a project as a percentage, ignoring the immune experiment with 0% interest and telling Sorae to come to him with something more interesting. As Shiro's abilities advanced his "percentage" rose until it hit 100% and he claimed he was "in love" with her. He also has an obsession with the Wretched Egg and wants to express "love" to her. He is manipulative for treating Tsunenaga Tamaki as a pawn. He is clever and decisive, and when he is inside Toto Sakigami's body he wants to express "love" using Toto's abilities.

At one point, he was a subordinate to Sorae Igarashi, and often commented on how 'harsh' she was. He was surprised when she suddenly softened after Ganta Igarashi's birth, and from then on, only grew frustrated with her reluctance to continue with the experiments.

He later 'adopted' Chan and En, who were twins born with half a brain each. Though they were clearly grateful towards him and even revered him as a father figure of sorts, Hagire outright stated to them that he didn't love them at all, though they knew this already and didn't care. He also took Shiro in after Sorae's death, and fed her all the candy and sweets she could ever want, and even appeared to allow her to do whatever she pleased at Deadman Wonderland; though, this wasn't done out of the kindness of his heart, and was again related only to his obsession with Wretched Egg.

Plot
When Ganta was taken to Deadman Wonderland, Hagire was still in this form, but his health was decreasing steadily. Eventually, he was killed in a fight with the Wretched Egg.

This is his current body, in the form of Toto Sakigami. He chose this form because he was an extremely strong Deadman. Toto's Branch of Sin seemed to be very helpful since Hagire needed every Branch to try to unlock the Mother Goose System.

For the fourth generation, Hagire wants to possess Ganta Igarashi, for he has the only Branch of Sin that is capable of unlocking the Mother Goose System and Toto couldn't copy it, so Hagire attempts to take over Ganta's entire body. Although Senji interrupted the process and saved Ganta, it can still be successful if the process continues within 60 minutes. However, it fails and Hagire lost an arm and a leg in Toto's body but he was saved by Yogusa who still thinks Toto is still Toto but still failing to realize that Hagire took over Toto's body.

He is eventually killed by Ganta later in a grand battle with the remaining Deadmen.

Abilities
When Hagire changes bodies, he adopts that body's abilities as well.

First generation
It is yet unknown if Hagire's original body possessed any special abilities.

Second generation
Branch of Sin: Deadman Wonderland's director already had a Branch of Sin, so Hagire had the ability to freely control his blood out of his body.

Unspecified Branch of Sin: The director also had the ability to use his blood as some sort of energy blasts or lightning bolts. His blood stays the same, but he fires it in a matter that looks like he is firing lightning.

Third generation
Branch of Sin: While in Toto's body, Hagire is a Deadman and has the ability to freely control his blood out of his body.

Branch of Sin: Love☆Labyrinth (ラブ・ラビリンス, Rabu Rabirinsu): This allows him to copy the abilities of other Deadmen. However, he states that he recently was reset of his copied powers after his battle with the Wretched Egg. But even in his weakened state, he managed to take down two of the Forgeries with nothing but a copy of Crow's powers. He has now almost every Branch of Sin there is, with the exception of Ganta's Advanced Ganta Gun.

The Branch he uses the most is Senji's Crow Claw. This is most likely because of its high attack power and speed.

Trivia

 * While in his third generation, Hagire has the ability to copy other Branches of Sin, but he cannot evolve their powers nor use their evolved forms if they are already evolved, such as Ganta's Ganbare Gun and Senji's unnamed evolved Crow Claws.
 * Interestingly, Hagire showed no desire to kill Ganta, unless you count wanting to take over his body. This is due to the fact that he needed his Branch of Sin to unlock the Mother Goose System, and obviously, he can't do that if Ganta is dead. Instead, Hagire took great pleasure in sharing his memories with him, carefully explaining every detail of Wretched Egg's origins, and his mother's (and by extension Ganta's own) hand in her creation. Once his attempt to take over Ganta's body failed, this didn't change; Hagire could have easily killed him in Haggard Absurd when Ganta was exhausted from unlocking the Mother Goose System and was unable to defend himself, but instead, he wanted Ganta to carry on his memories, and even reminded him that Shiro was his replacement in the experiments.
 * Hagire (while in Toto's body) is a cannibal for eating human remains of other Deadmen.
 * Hagire's dressing style is that of a hippy in all of his forms. He always wears light and roomy clothes, usually white long shirts, loose pants and flip-flops in his first form. He also has a messy hair that is kept in a ponytail in his first form. But unlike hippies joyful personality, his is very violent and disturbing.
 * Both, him and Ganta fulfilled their promise to Shiro. While he was the one to release her from her binds, Ganta was the one who stopped her.
 * Despite Hagire never calling Chan and En his children, unlike them calling Hagire their father, he is technically their adoptive father.
