In the World Protection Security Agency stories, he and the rest of the main Black Bullet cast are recurring characters of the story. He is revealed to be the long-lost cousin of Yukina Himeragi.

## Appearance

Rentaro Satomi is a young teen of small frame and messy dark blue hair, with slightly slanted eyes and blue irises. His dark blue hair partially covers the whole of his forehead; reaching down below his eyes with a parted set of bangs untidily forming. Rentaro possesses thick sideburns connected to his hair which hang loose around his cheekbones on either side. Further; several strands of his unkempt hair, having gaps in several locations, arch around his thin eyebrows and hover on top of his thick eyelashes. His nose serves as roof to thin lips and a small jawline. He has small ears and normal-sized feet. Despite his profession, Rentaro shows no scars in any visible part of his body.

Rentaro dons a black suit covering his body entirely. The jacket, which he leaves open with solely one button connecting the two sides in the center, displays a much lighter color in the inside; resembling the color light blue. On the right side, there's a strap of the same light blue color linearly craved from the collar of the jacket to the bottom. Additionally, the inner collar displays thin black lines similar to the ones on the strap. Underneath the jacket, there is a notable white shirt with a large turtle neck held together by a blue tie around his neck. Around his wrist, Rentaro keeps the large blue cuff, with a small white line circling around the middle, folded accordingly. The shirt underneath the jacket is kept in messy standards, as one of the sides is inside the pants whilst the other is left out in the open. Rentaro's lower body is sheltered by a pair of pants that are held around his waist by a blue belt with a small white line encompassing around the center; serving as a form of adornment. The back of the black pants show two pockets, each serving as inventory for his wallet containing his Civil Security license. He travels around in high black shoes that have a much lighter color at the bottom.

## Personality

Rentaro, whilst seemingly low-tempered, is a loving young boy that, despite public view, treats everyone; the Cursed Children included, as equal. Said statement is further emphasized when Enju, she herself being a Cursed Child, is mistreated by her school peers due to the Gastrea blood running through her veins; Rentaro unthinkingly exits his own school to go to her side. However, under pressure and when in situations where he has no control over, he acts towards them like most of society, even to the point of solely watching a cursed child being abused by humans and slapping her hand away in an un-wantonly manner. Albeit, he does repent over his actions and later helps the child that was left at the gates of death by human hands.

Rentaro shows, however, anger when spoken to of his dead parents. When Kisara inquisitively questions his ambition to "find" them, he burst out into a cry of vivid fury and abruptly leaves her without saying another word. He sometimes portrays lack of confidence when it comes to his skills as a fighter, even to the point of dropping a mission given to him by the agency. Even so, when faced with threats greater than him, Rentaro retains his calm nature and gains the strength he needs to protect the ones he cares for. He also cares deeply for Kisara and have shown some feelings toward her.

In the WPSA stories, Rentaro shows to be antagonistic and bitter whenever his long-lost cousin Yukina Himeragi is mentioned in the conversation or even seen a few miles away from him. This is largely due to Yukina being able to live a much better life from another universe, and this outcome led Rentaro to completely lose it. For years, he shows to always bury any mentioning of Yukina, but to no avail, which leads him to being thrown into a state of psychosis.

## Relationships

### Enju Aihara

When the two first met, Enju's distrust in humans lead their encounter to a rocky beginning. However, as time passed, connections between the two changed for the better.

Rentaro treats Enju like family, albeit; Enju seeks for a deeper relationship with the Civil Security member which usually comes off in a comedic manner. Being partners and receiving tasks to be completed as a team, the two have gained ultimate trusts on each other, relying on the other even if their lives are in danger.

During a mission to take down a Stage I Gastrea, Enju plants a kiss on Rentaro's lips, but soon enough kicks him for leaving her behind, claiming herself to be his fiancé. Despite this, however, she displays supreme adornment to his skills; noting his bravery when he fought and overpowered said Gastrea alone. Rentaro believes that Enju is just as human, or even more, as the people around her, even to the point of admitting that he will guide Enju through the correct path. When people refer to Enju as a monster, Rentaro is unable to keep his emotions in control; bursting out in angry cries as he defends her image. Said statement is further proven true when the boy receives a phone call from Enju's school informing him that her identity of being a cursed child is public, rushing to her side (desperately looking for her in the process) in mere seconds and consoling her as well as protecting her from the kids calling her a monster.

When they were alone in a forest where Kisara located the original source of the Gastrea, Enju admits to Rentaro that she wishes to protect everyone, whilst her vision is clouded by tears falling down her face. Moved by her words, Rentaro hugs her tightly and reminds her that, even though she is accused of things she did not commit, he will always be by her side as any family would. Enju then weeps as she embraces Rentaro. Henceforth, the bond between the two has ultimately strengthen.

### Kisara Tendo

Kisara is one to usually badmouth Rentaro's abilities and lack of responsibilities: calling him useless, an idiot and even threatening to kill him. Although at oftentimes it arises as conflicts between the two, they don't remain arguing for long. Rather; continue displaying their family-like bond. Kisara holds great respect for Rentaro's bravery, however, seeing as he saved her from a rampaging Gastrea when she was young and the two were living under Kikunojyo Tendo's care, as well as when Rentaro heads out to fight Kagetane, she gives him her full trust on victory. When Rentaro witnesses Kisara's sorrow over an issue with the Tendo and her parents whilst the latter talks in her sleep, he assures her that he will avenge the Tendo.

### Kikunojyo Tendo

Although not much is known of the relationship Rentaro shares with Kikunojyo, it has been stated that when Kikunojyo first offered Rentaro his own home to live in as a Tendo, the young boy denied. However, as time progressed, Rentaro undoubtedly accepted and lived under his care. Kikunojyo also protected Rentaro against a Gastrea, and gave him the advice to live rather than die in despair.

### Tina Sprout

Rentaro seems to be on friendly terms with Tina Sprout, a Model Owl Initiator. He first met her when she was being surrounded by three men for one over the foot of one of them, and in that, she calls him a superhero. Shortly after, the two exchange numbers after a small conversation. Previously, Rentaro had no idead that Tina was the sniper, as she had no idea he was the one who foiled her assassination. Some time later, the two are seen hanging out on a bench, to which he feeds her food he had made for her. This prompts Tina to say she likes Rentaro because of how kind he is towards her, never having someone like that. That same day, the two meet again, but as enemies, to which Rentaro save Kisara from Tina's assassination attempt. Tina tries to reason with Rentaro, but to no avail, much to the fact both are equally shocked. However, as of now the status of relationship seems to be strained, with Rentaro vowing to stop her.  The two did meet up to fight each other, however Tina at certain times overpowered Rentaro, but she couldn't pull herself to kill him, which resulted in her defeat. However, following the events after fighting Tina, the friendship between the two seems to have been rekindled, with Tina stating that she looks forward to working with him. Rentaro responds that whatever happens in the future, he will not be held responsible for it.

### Miori Shiba

Miori is a fellow classmate of Rentaro at Magata High School. Miori is the president of the Student Council at their school and daughter of the president of Shiba Heavy Weapons. The two first met at some point prior to the beginning of the current story. Her company is also responsible for distributing the Varanium bullets he uses, which he receives for free. According to Miori herself, their were conditions met with Rentaro obtaining free bullets, as such were studying in the same school. She is seen to have feelings for Rentaro as on few occasions she has tried to seduce him, leaving him uncomfortable. She is often willing to help him when he asks her a favor, such as requesting information on Sogen, but she always requires something in exchange, such as spending time with him, and uses their time alone to her advantage, although the moment was obstructed by Kisara.

### Syouma Nagisawa

Syouma is an old friend of Rentaro, and his martial arts superior. The two seem to be well-antiquated and get along very well. Rentaro has a deep respect for his abilities and addresses him as Syouma-nii.

### Yukina Himeragi

In the WPSA stories, it is revealed by Max Payne that Rentaro is related to Yukina through the dossier the WPSA retrieved from the erstwhile living Victor Branco in Bahia, before Max leaves. But when the WPSA and Yukina comes to the Black Bullet universe, they discovered that she, along with Rentaro, were the survivors of the Gastrea attack, and her parents were unfortunately killed, alongside Rentaro's parents. Unlike Rentaro, however, it was her parent's choice to send her to the Strike the Blood universe as an orphan, where she completely loses all of her memories of the horrors of the attack, as well as her relation to Rentaro as a cousin. Despite Rentaro being separated by Yukina for 10 years, who wants to see her again, this does not play out well, when it is revealed by Kisara that his relation to her as a cousin has gotten so sour and completely damaged that Rentaro made any attempts to not see Yukina again. This hate of Yukina later extends towards Enju and Tina, though the two don't seem to follow his sentiment, but they do it to not provoke Rentaro furthermore. This is because Yukina was fortunate to live a life from another universe away from the horrors of the Gastrea attack, despite the ongoing madness and chaos in there, as well as her being in a relationship with Kojou Akatsuki. Rentaro was always in a state of despair, who is trying to find a purpose of living, despite having Enju always on his side and his job as a member of Tendo Civil Security, which was the sole reason of his increasingly distant relationship towards Yukina as his cousin. Through blood, sweat, and tears of the WPSA, as well as Kisara, Enju, and Tina, Rentaro's strained cousin relationship with Yukina has finally been mended, when the two later battled each other, with Yukina being the victor. Rentaro, after the battle, was astounded and shocked at Yukina's combat expertise. Soon after it has been fixed, Yukina starts calling Rentaro "Ren-nii", where she admits that Rentaro is the only family memeber left that she truly cares for, after the Gastrea attack that killed her parents, as well as his own parents.
