"Corpses are good. They don't babble. Only they can understand my feelings."
Sumire Muroto (菫室戸, すみれ むろと, Sumire Muroto) is a researcher at the Magata Public University Hospital, which is a medical school near Magata High School, and is Rentaro's Sensei. She is one of the Four Sages and the person in charge of the "New Human Creation Plan" in Japan.
Sumire Muroto is a young doctor of average height and body frame. She has messy, purple hair that covers the whole of her forehead, as well as a prominent bang entirely covering her right eye and parts of her cheekbones. Arching around her eyes are a pair of thin eyebrows and, underneath, two slightly thick eyelashes which encompass her oval eyes and light irises. Sumire's hair, which juts out in every direction, but is kept moderately straight in the back, falls directly below her neck. Sumire possesses thin lips and a small nose.
Sumire dons a white, open-coat: true to her profession, that falls below her feet and covers most of her body. Under said garment is a shirt with a large collar circling around her neck, as well as a dark skirt covering her thighs, but leaving her legs' lower regions exposed, which are covered by a pair of dark tights. Around her neck, a small necklace can be spotted, as well as her name-tag located on her coat.
Sumire Muroto is an easygoing, charismatic woman. She enjoys playing pranks on Rentaro Satomi, seeing as he is one to be easily scared by eerie happenings. Similarly to how the others around Rentaro call him weak, Sumire is no exception as she shows no pity when naming his faults. Sumire also enjoys toying or misinterpreting Rentaro's words. Despite her carefree and lively persona, Sumire was filled with sorrow when Gastrea first started to take over mankind, stating that not even a thousand words could explain the agony she felt at that time.
The Cursed Children arcEdit
Sumire, hiding her presence behind a sculpture; personifying the object as she calls it her husband, scares Rentaro when the boy walks into her lab and sees the "moving object." She comments on how he is still weak against creepy things, and then welcomes him to her place, calling it an abyss, as she hugs the sculpture. She informs Rentaro that the Gastrea he defeated was brought to her lab, and confronts him for not killing it more cleanly. She approaches his face and tells him that the impact of the bullets damaged the meat and are all over its body. She compares Rentaro to Nobi Nobita from the a popular manga, claiming that his shooting skills are far better than Rentaro's. She calls him hopeless and questions him for not committing suicide yet, following her dark conversation by asking him if he has already lost hope in the world. Not receiving a direct reply, she simply takes a seat and admits that if he will act like this Kisara will dump him, making him shudder and blush at the thought. Rentaro reminds her that a person like Kisara would have someone with Rentaro's abilities defeated in mere seconds. However, in return she recollects the time when Rentaro was helped by Kisara when he lived with the Tendo and her brothers would pick on him. Dismissing their conversation, she tells him that it's time to get back on track.
The two talk about the characteristics of a Jumping spider, claiming that the Gastrea virus gifted the infected with a new ability, calling it Evolutionary Jump. However, Rentaro tells her that he believes it was able to camouflage itself, but Sumire admits that if it is true, the Tokyo Area will be no more by tomorrow. When Rentaro mentions Enju and Civil Security, Sumire begins to recollect the summering Cursed Children during the time Gastrea began to take over mankind. She states that the Gastrea virus was able to give them enhanced abilities. Before Rentaro leaves, she tells him to come visit her again, in a comedic way.
Sometime later, she is visited by Rentaro once again, who comes to her lab asking her for advice on what happened to Enju and the small girl that was shot by the police not so long ago. However, Sumire, distracted, tells him that she was thinking about what snack to eat. She quickly gets serious as she talks about the people that view Gastrea as God's wish to clean the world of its pollution. Commenting on how the Cursed Children are messengers from God to carry out the task of observing the Gastrea and humanity, Sumire is met by an angry Rentaro who tells her that Enju is human. Before he can confront her further, she extends her arms out and informs him that he now understands that he and Enju are family. Rentaro runs out claiming that he now understands, thanking Sumire along the way.
Legacy of the Seven Stars arcEdit
Sumire greets Rentaro when he comes to her lab to prepare for the upcoming battle against Kagetane. She asks him if what he has is enough, to which Rentaro responds affirmatively. She tosses a pack of AGV Experimental Drugs at him, advising him not to use it unless ultimately necessary. She admits that if he were to die, she will lose her visitor, causing him to smile slightly. She then tells him that when Gastrea first began, her world turned upside down. She questions how to apologize to him for what she did when she "lost herself." However, Rentaro tells her that there is no need as he has no hate for her. Before walking out of her lab, he points his thumb upwards and promises to return, causing her laughter. She tells him to become a good man benefiting of those words, expecting him not to die.
After handing him the drugs, Sumire is instantly questioned about its contents. Briefly, she reveals that originally she was researching for antibiotics for the Gastrea Virus; stating that an AGV Experimental Drug accidentally came to being—a drug that utilizes the Gastrea Virus to grant the user superhuman healing capabilities for an hour, infecting them with the Gastrea Virus. She further explains to him that when the time for him to cross that line comes, it should be within his knowledge that he may forfeit his humanity.
Sitting in her chair and using her laptop, Sumire turns to look at the visitor knocking at the door, Kisara. The doctor quickly and warmly questions her sudden arrival, only to be thanked by Kisara for saving Rentaro's life; claiming that if not for her intervention, Rentaro would be dead. Sumire attempts to dismiss her gratitude, asking about her abrupt sweetness and even admitting that if she acts this sweet around Rentaro the latter would not hesitate to lupin dive her. Quickly enough, Sumire witnesses as Kisara lowers her head and blames herself for not being able to stop Rentaro from going. However, Sumire, placing a warm cup on the table, reveals that Rentaro would have gone regardless. As she walks towards her laptop, she recites Rentaro's words to Kisara before the latter left to find Kagetane, which shocks her. Subsequently, Sumire admits that she wishes to believe in those words.
Moments later, after Kisara leaves her laboratory and heads to the meeting held by Seitenshi, Sumire appears on a television screen, telling the men present to stop praising her when they state that Rentaro's lost limbs look perfectly normal—something which Sumire herself performed when Rentaro was attacked by a Gastrea. Being told by Seitenshi to get back to the matter at hand, Sumire sends data of Rentaro's Varanium limbs, shocking the whole of the meeting as she reveals that Rentaro is a Mechanical Soldier.
Sumire watches as Rentaro momentarily gains the upper hand; largely overpowering Kagetane with his Varanium limbs. However, the boy is soon impaled by Kagetane's Endless Scream. The doctor is subsequently asked by Seitenshi if utilizing another injection would restore the lost organs. She responds negatively, informing the protector that if he were to inject himself one again with the AGV Experimental Drug, a new Gastrea will be born. Gazing towards the ceiling of her laboratory, Sumire exclaims that it is over.
Sumire is a figure of supreme knowledge to Rentaro, frequently listening to her opinions before taking action; as shown when he questions her about the Gastrea's abilities to enhance their body features. Further; he refers to her as his "Sensei." She commonly pranks him when he enters her office, as she states that she knows him extremely well to know what frightens him. Similarly, she usually pesters him by claiming that with his current abilities Kisara will not love him back, which angers him. During a conversation the two shared, Sumire attempts to apologize to Rentaro for "losing herself" during the Gastrea War, but Rentaro stops her and informs her that ever since that day, he has never hated her for her actions. When he gets ready to leave her office by parting with a well known quote, she burst out into laughter and begs him to return alive; as he is the sole visitor she has, as well as telling him to become a man benefiting of his words.
