First Appearance
Debut Chapter 1; Episode 1

Shirō Onijima is the father of Utsutsu Hasegawa and Yume Hasegawa. He is a deranged abusive man who belongs to a secret organization.

AppearanceEdit

His usual attire is a formal black suit. He has short black hair and black eyes with glasses. However, it's debatable if he can see without them, since as a child and teenager he was seen without them.

PersonalityEdit

Shiro is a proud man that resolves everything with violence. He enjoys beating up his children, especially Utsutsu, and previously his own wife. He is the kind of stubborn man who get's a 'kick' out of terrorizing others. He believes that he can do what he wants, and that he is the boss of his household and of others.

His complicated personality is because as a child he was abused by Genjurou Imari and it's implied that because of his contacts (such as Bizen), he was also experimented on. While it gave him super strength and endurance, it also made him unable to openly show affection and use violence for everything. He is also only violent with his loved ones, because as seen in the omakes, with his friends from the organization, Haruka and Ryuichi he behaves normally.

It's revealed that he was abusive towards his wife and son because of a misunderstanding. He was aware that Yume wasn't his child, but since at the time he didn't know about the Pupa virus, he believed that Sachiko betrayed him.

He is also not really being responsible for the bad things that happened, since Utsutsu is an unreliable narrator. Apparently Utsutsu's wounds were given to him by Yume, when she lacked common sense after being recently incarnated from human to monster as a child. However, since Utsutsu is imprinted to Yume, his mind reject that notion and believes Shiro abused him. He als genuinely cares about Sachiko and Utsutsu, but he is too proud and violent and can only show his love with violence. After he finds out that Yume is monster incarnated as a human girl, he decides to protect Utsutsu from her, in his own way.

Background Edit

Young Shiro abused and locked on

As a young child, Shiro was given off to Genjurou Imari, Maria's grandfather. For years he was locked in his house, physically abused and used him as little more than a toy. Genjurou often stripped him naked and whipped him, just for the sake of inspiration for his paintings. It was the combination of the abuse and Genjurou's rare times when he was nice to him that convinced Shiro that this pain was Genjurou's love for him, fueling his entire "love is pain" philosophy.

It's implied that since Genjurou knew Chiharu Bizen, they also experimented on him, explaining Shiro's abnormal strength and resistance.

Years later, Genjurou commited suicide, so Shiro ran away. However, he could not live a normal life after all the abuse, so he joined a mysterious organization, where he could use his strength and endurance. After those years of abuse, Shiro became unhinged, hence why he believes that hurting those you love is the greatest form of affection and enjoys hurting his loved ones (Sachiko and Utsutsu).

HistoryEdit

MangaEdit

C018

Shiro hurting Utsutsu

At first, Shiro is introduced as the abusive patriarch of the Hasegawa family and was the one who gave Utsutsu the scar across his eye. He is shown to care about Utsutsu somehow, such as searching for him and Yume after they're kidnapped. However, the first thing he does upon reuniting with him is to warn Utsutsu about Yume and to give him a beating after he doesn't listen. 

After Utsutsu and Yume are on the run, he decides to pay his ex-wife Sachiko a visit, to know more about the Pupa virus. However, since she freaks out upon remembering the awful truth about Yume, the doctor Chiharu Bizen proceeds to explain Shiro the truth. It turns out Shiro and Sachiko married after she was pregnant and he was actually excited to be a father. However, he had to go to work overseas and left the pregnant Sachiko.

Also, Yume is actually a monster that was created in a laboratory. She escaped the laboratory and entered Sachiko's uterus. The monster had the ability to mimic, so once inside of Sachiko, she had copied everything about her host-mother. Thus, resulting in Yume having the exact same DNA as Sachiko. When Shiro came back from overseas, he was very angry when he saw the was another child besides Utsutsu. Believing that Sachiko betrayed him, he started becoming abusive towards her as a result. Sachiko shortly abandoned the house, because she was creeped out by Yume, because she was aware the child was a monster. When Utsutsu demanded to know why their mother abandoned them, Shiro lied to him, by saying that she was seeing another man.

Shiro attempting to put some reason on Utsutsu

With this knowledge, Shiro, together with his partners Haruka and Ryuichi, goes looking for Utsutsu and Yume (who is stuck in her monster form) again and finds them hiding in a forest. After beating Utsutsu once again, Yume goes into one of her rampages again. Shiro continues to beat Utsutsu, claiming that he does that because he loves his son very much, which is confirmed after some flashbacks about Shiro's abusive childhood, with his captor convincing him that pain was love. Suddenly Utsutsu slowly starts mutating into another Pupa monster and calls out his father for his distorted vision of love and impales him with a tentacle, fatally injuring him. However, Shiro survives the mortal wound.

When Yume calms down and returns to her human form, Shiro carries the unconscious Utsutsu to safety as he tells Yume that she should stop calling him "brother". Just then, Maria appears, having impregnated with the Pupa Virus and turning into a flesh blob. She kidnaps Yume in an attempt to assimilate with her, absorbing Utsutsu, Shiro, Haruka and Ryuichi in the process. When Utsutsu wakes up, he realizes that Yume is gone. Utsutsu has accepted that Yume is not his real sister and is a monster, but as he rationalizes it, he is transported to the bottom of Maria-Yume's monster form. 

Shortly, Utsutsu gets out of Maria, after coming to terms with the truth about Yume. However, this is too much for him and becomes a monster. Shiro watches helplessly and starts calling out his son in vain.

Shiro watching as Utsutsu and Yume dissolve into butterflies

It's revealed that Utsutsu didn't mutate into a monster, because he was already one. After Sachiko abandoned them as children, Utsutsu became very depressed, so Yume went out in the streets to search for Sachiko. However, she didn't see an incoming truck on the way. Utsutsu, who was searching for her, protected her with his body, but ends up getting himself killed instead. As it turns out, Yume didn't need protection because she could easily regenerate from her injuries and feed the dying Utsutsu some of her flesh, so he could revive as a monster and became imprinted to her.

After Utsutsu and Yume dissolve into red butterflies and fly into the distance, Shiro looks at the scenary helplessly, since in the end he was unable to save Utsutsu.

AnimeEdit

Because the anime was short, it only covers the first part of the manga, when Yume transforms into a monster and she goes berserk after Utsutsu is dissected alive. Shiro is portrayed as an abusive father. The fact that he is affably evil and he actually cares for Utsutsu are left out.

Skills Edit
