"I was the last one left back then, and that's how it's always been till now. That's why I have to take them with me. I'll take everyone who fought and died alongside me to my final destination." ― Shin to Lena, regarding his promise.
His Personal Name is Undertaker (アンダーテイカー, Andāteikā?).
He is the leader of the Spearhead Squadron, as well as the default operations commander of the Eighty-Sixth Strike Package. Among the Eighty-Six, he is known as the Reaper of the Eastern Front. His ability to hear the voices of the Legion allows him to locate them without the use of detection systems.
Shin has the bloodred eyes of a Pyrope and the jet-black hair of an Onyx. His pale features and slender physique are characteristic of the Giadian Empire's nobles. He is described to be rather handsome, attracting the attention of a few of his female comrades.
Shin almost always wears a sky-blue scarf to conceal the jagged scar on his neck. He obtained this scarf from the captain of his first squadron—Alice Araich. Before he was gifted the scarf, his scar was concealed by bandages.
As the Spearhead Squadron's leader, he wears a desert camouflage uniform scavenged from an abandoned Republic military depot. He later switches to the Federacy's steel-colored panzer jacket uniform, but retains his blue scarf, removing it only for official meetings.
Shin is an incredibly kind person, even after being wronged by so many people in his life. He considers himself to be at fault in the matter with his brother and believes he is the one that needs to apologize. Even after being ostracized and feared by the other Eighty-Six, Shin felt that it was his responsibility to shoulder the deaths of his comrades and let them pass peacefully into the afterlife.
He had always been the only person left alive until he met Raiden Shuga. Thus, even after meeting a companion that could survive along side him, he always felt it was his duty as the survivor to silently carry the tags of the fallen to his final destination. Even once letting go of his fallen comrades on the border between San Magnolia and Giad, he still used his comrades' deaths as an excuse to return to the battlefield.
Shin's ability to hear the voices of the Legion places enormous mental strain on him, even when he has become accustomed to listening to the constant wails of the dead. The weight of both his responsibilities and the effects of his ability have contributed to his stoic nature and lack of mirth. Despite that, he has a gentle side to him that usually comes out when interacting with Fido.
His kindness also manifests in selflessness to an extreme degree. This is demonstrated in when he chooses to face the Shepherd alone to put his brother to rest, as well as when he forcibly takes control of the Spearhead Squadron's last Juggernaut and attempts to hold off the Legion so that the rest of his squadron can escape.
Shin had a distinct lack of care for himself. He compared himself to the Legion, calling himself a ghost, aimless and wandering. Consequently, he often threw himself into dangerous situations without regard for his own safety, somehow surviving through luck and combat skill. This tendency grew worse once Shin had completed his mission of putting his brother to rest and losing his raison d'etre.
Even once he reunited with Lena and was pulled out of his suicidal craze, he still could not fathom that he was allowed to be selfish. He believed he could live even without a future to look forward to, or happiness which he could call his own. When Lena asked him for a wish he wanted fulfilled, he couldn't think of anything. His answer in the end was to take Lena to the sea, which he admitted was probably different than what Lena's question had intended.
Shin eventually did realize his feelings for Lena. Once he confessed them to her during their stay in the Alliance of Wald, he was noted to be free of the shackles of pride binding him to the Eighty-Sixth Sector. He now genuinely had a future to look forward to, as well as a new found attachment to the world and humanity.
Shin is known as the Reaper of the Eastern front, a practical legend among the Eighty-Six. Both a moniker of reverence and fear, those who were assigned in the same squadron as him dreaded their fate of certain demise, or accepted that they would die knowing Shin would carry on their memory. No one would survive long term in a squadron with Shin present, no one except the one known as Wehrwolf.
Shin is often compared to a plague bringer or a prophet of death. His notoriety would spread from the word of his previous mechanics or squad mates which were transferred out of his squadron, such as Rito Oriya. His reputation would achieve a similar status in the central Republic military, due to stories of him breaking his Handlers and driving some to suicide through his ability to hear voices of the dead.
After entering the Federacy military, Shin soon earned a similar fearsome reputation due to his cold demeanor, headless skeleton mark, and exceptional combat skills.
Born on May 19th in Republic Year 351, Shin lived with his family in the First Sector of the Republic before the war with the Giadian Empire began. It is implied he lived a sheltered life, surrounded by "only kindness and affection". He also appeared to have developed his extrasensory ability early on, hearing "voices that spoke without words" from his family. He would often play with the daughter of his father's colleague, Henrietta von Penrose, whom Shin called Rita.
Shin and his family were forced to relocate to an internment camp when the war began due to the Republic's discriminatory policies. Shin's father was first to enlist in the Republic military, accepting the Republic's promise that Shin and the rest of his family would have their rights restored in exchange for military service. Despite this, the Republic does not uphold its promise. Upon delivering the news of Shin's father's death, it informs Shin's mother that the military service was in exchange for only one person's citizenship. Continuing to trust the Republic, Shin's mother also enlists to protect her sons, leaving eight-year-old Shin and his eighteen-year-old brother Shourei in the care of an Adularia priest, a friend of the Nouzens who had resisted the Republic's policies and remained in the village-turned-internment-camp's church.
Shortly afterward, Rei receives notice of his mother's death on the battlefield and an enlistment form for him, proving the Republic's promise to be a lie. Shin, to whom the concept of death was not yet comprehensible, implores Rei to explain why their mother would not be returning. Shin's pleas caused the grieving and frustrated Rei to snap and choke Shin in a fit of violent rage. Rei brings Shin to the brink of death before the priest intervenes and resuscitates him. Shin is left with a jagged scar around his neck as a reminder of his brother's hatred. The near-death experience also opens Shin's telepathic ability to a broader range of human consciousnesses, including those of the Legion, by temporarily experiencing the post-mortem collective consciousness of humanity. Rei avoids Shin after the incident and refuses to say farewell or even glance at Shin when he enlists and leaves Shin behind with the priest.
Four years after Rei's enlistment, Shin hears his brother's voice among the laments of the Legion and realizes that Rei is dead. On that day, Shin enlists with the military and becomes a Processor.
A genetic feature that is seen in people of Pyrope heritage. Those with the extrasensory ability can communicate with family members by hearing their thoughts. This ability makes use of the part of the brain known as the Night Head and is the basis for the Para-RAID's communication abilities. The range and limitations of the ability are unspecified in people other than Shin.
In Shin's case, his ability was originally restricted to only his family, the same as others with the ability. However, during his near-death experience after being attacked by his brother, Shin's consciousness temporarily entered the abyss of death, and he was able to hear the voices of those who had died. Upon being resuscitated, Shin retained the power to hear the voices of the dead that were still among the world of the living. The ability allows him to detect the Legion because the Legion was designed with the human neural system as a basis for their central processing system. While the Legion's original replica processors are not as easily detected by Shin, being more of an electric haze to his ears, the Legion's processors which have derived from the neural systems of dying Eighty-Six create easily distinguishable, and haunting, voices that Shin can hear.
The voices Shin hears can be transmitted through the Para-RAID. By turning the synchronization rate of his Para-RAID to the maximum, Shin has traumatized many incompetent and abusive Handlers with the haunting voices to the point that one Handler commits suicide. When linking with other Processors, Shin turns the synchronization rate lower. The transmission of voices also allows linked Processors to determine the positions of nearby Legion using the voices' distance and direction.
Shin's combat skills are unmatched by other Processors, as he has honed his skills to levels far above the other veterans. Combining his reflexes and telepathic ability, he can perform attacks that no other Processor can do, such as charging three Löwe at once in a frontal attack. His Undertaker is specialized for his melee-oriented combat style, replacing its standard machine guns with high frequency blades, with all of its limiters being broken to maximize mobility. Due to this, however, there are situations where he could be completely useless against long ranged targets once his main smoothbore gun ran out of ammunition.
He is also proficient in hand-to-hand combat, taking down the much larger Raiden in a fistfight and stating that he could disarm and kill three Republic soldiers before they can even remove their safeties. His proficiency in various forms of combat ties back to his heritage as a Nouzen, an Onyx clan that served as the Giadian Imperial guard.
- "Dicit ei: Legio nomen mihi..." (He replied: My name is Legion...)[† 1] ― Mumbling to himself before a sortie.
- "This is the best outcome I could have hoped for, but you guys got the short end of the stick... What will you do? Knowing that you'll die tomorrow, will you hang yourself today?" ― Shin to Raiden, regarding the Special Reconnaissance Mission and their upcoming battle with Shourei.
- "If, one day, you make it to our final destination, would you please leave flowers?" ― Shin to Lena, handwritten on a piece of paper.
