Rinichirō Hagire

Hagire Rinichirō a.k.a The Director was the main antagonist in 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 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. It is possible that Hagire modified them as well.

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 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 current form is that of Toto Sakigami.

Personailty
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 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 obession 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 insde Toto's body he wants to express "love" using Toto's abilities.

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 did a research on how to heighten a person's immune abilities and tested on several "guinea pigs", including Shiro. In the beginning, he wasn't interested at all, but when Shiro's body began increasing the number of the Nameless Worm, gained 20-30% interest, enough to do an experiment, which caused the birth of the Wretched Egg.

At some point between this happening and the Great Tokyo Earthquake, Hagire was either severely damaged or nearly killed, and his body was no longer fit to be used. Through circumstances unknown, he overwrote his memories in the body of the future Deadman Wonderland director, the old man, whose true identity is a mystery.

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.

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

Third generation
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.

Fourth generation
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 interupped 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 realise that Hagire took over Toto's body.

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

Abilities
Every time 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: DW'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 mostly likely because of its high attack power and speed.

Trivia

 * Hagire shares similarities with Orochimaru from the popular manga and anime series Naruto, in that they both have the ability to take over the bodies of another as well as gaining their abilities.
 * While in his third generation, Hagire has the ability to copy other branches of sin, however it appears that he cannot copy evolved branches of sin, such as Ganta`s Ganbare Gun.
