Rentarou Satomi

Rentarou Satomi is the main protagonist of the Black Bullet anime and light novels.

Rentarou is a 16-year-old protagonist of Black Bullet and Enju's promoter of Tendo Civil Security.

In the AWA fics, Rentarou is a student at the AWA Academy.

Appearance
Rentarou 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. Rentarou 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, Rentarou 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, Rentarou 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. Rentarou'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
Rentarou, 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; Rentarou 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.

Rentarou 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, Rentarou 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.

Equipment
Springfield XD: Rentaro is in possession of a, as he states, normal black gun. He carries the gun on the back of his pants, using it when he is the midst of a fight. He has shown great mastery over said weapon, shooting a Stage I Gastrea repeatedly without showing any signs of fatigue and with the ability to maintain his stability throughout the process. AGV Experimental Drug: Rentaro was given five needles by Sumire that contain AGV Experimental Drug within. He was told by Sumire herself that this Experimental Drug contains artificial Gastrea Virus that grants him superhuman healing abilities, and is only to be utilized as a last resort weapon; the user may forfeit their humanity. When Rentaro injected himself with a needle in his abdomen, he releases a loud and vigorous roar that intimidate those around him.

This non-lethal weapon is additionally used as a form of diversion for future assaults.

He himself states that with said bullets, Gastrea will not be able to recover; giving him the upper hand when in combat. These Black Bullets were able to harm a Stage I Gastrea greatly, in contrast to when Tadashima attacked with regular bullets; to no effect.
 * Superhuman Healing Capabilities: After injecting himself with a sole dose, Rentaro's wounds begin to heal instantaneously. Additionally, Black Bullets, previously shot by Kagetane, exit his body, with the wounds healing themselves and appearing unharmed; smoke arising and evaporating into the air. The speed at which the wounds can heal themselves appears to be rather swift, as a wound caused by a bullet heals in a mere amount of seconds.
