Description
Guren Ichinose is a tall young man of twenty-four with medium-length black hair, usually parted in the middle with bangs hanging over his forehead, and small purple eyes. He serves as a Lieutenant Colonel in the Japanese Imperial Demon Army and is the leader of the Vampire Extermination Unit known as the Moon Demon Company, as well as the commander of his own Guren Squad. His standard uniform is the Japanese Imperial Demon Army's double-breasted black coat with gold buttons and red details, complemented by white gloves and a sword belt.
Born on August 28 into the Ichinose family, a lower branch family despised by the ruling Hīragi clan, Guren endured harsh treatment from a young age. As a child, he shared a close friendship with Mahiru Hīragi, but they were forcibly separated due to their families' difference in status, an experience that motivated him to train desperately to gain power. Throughout his adolescence, he pretended to be weak and incompetent to avoid attracting the attention of the Hīragi family, but his true abilities were eventually exposed, leading Kureto Hīragi to force him into service through coercion and torture.
Guren's personality presents a complex duality. In his normal human state, he is a wise leader who values teamwork, cooperation, and friendship, believing these qualities are essential for humanity's survival against demons and vampires. He cares deeply about his comrades and subordinates, considering them family, and pretends to be lazy while actually working extremely hard behind the scenes. He keeps many secrets and lies about them without difficulty, harboring a long-term plan to dethrone the Hīragi family and change the existing hierarchy. Kureto Hīragi himself acknowledges that Guren possesses love, friendship, and honor, and that he cannot set aside his emotions to be a cold leader, but Kureto considers this very trait the reason he can trust Guren never to become a true threat.
However, Guren wields a possession-type cursed gear of the Black Demon series called Mahiru-no-Yo, which contains the demon of Mahiru Hīragi. When overtaken by this demon, he becomes a Namanari, a state where his personality changes drastically. In this possessed form, he becomes utterly ruthless in pursuing his goals, killing both vampires and his own human comrades to use them as sacrificial pawns. He exhibits a fundamental detachment from normal social behavior and appears to have no survival instincts, showing apathy even when faced with immediate danger. While still somewhat himself in this state, the Namanari version of Guren can murder freely and take extreme measures without hesitation, feeling at ease around dangerous situations.
Guren's motivations are driven by his desire to protect his comrades, ensure humanity's survival, and ultimately undermine the Hīragi family's dominance. He secretly works with high-ranking vampire progenitors while simultaneously leading military operations against vampire nobles, maintaining a delicate balancing act between various factions. He is also involved in the Seraph of the End experiment, gathering potential black demon holders and using subjects including Yūichirō Hyakuya as test subjects.
His key relationships are extensive and complex. He acts as a father figure and mentor to Yūichirō Hyakuya, having found him after his escape from the vampire city and trained him as a soldier, though he also secretly experiments on Yu as a Seraph of the End guinea pig. Shinya Hīragi, despite being adopted into the family Guren ultimately opposes, is his close friend who often teases him and joins him on dangerous missions. Sayuri Hanayori, his attendant since childhood, cares deeply for him and has an unrequited crush on him, while Shigure Yukimi serves as another loyal attendant who remains by his side. Kureto Hīragi serves as his ruthless superior who respects Guren's intelligence but does not hesitate to use torture and hostages to control him. His relationship with the demon Mahiru inside his sword is deeply personal, as she was his childhood love who became a demon and now influences his actions from within his cursed gear.
Throughout the story, Guren's development shows a man who has endured years of abuse, loss, and manipulation, transforming from a child who pretended to be weak for survival into a powerful military leader who operates in moral gray areas for what he believes is necessary. His struggle against becoming a full demon represents an ongoing internal battle, as the line between his humanity and his demon-influenced side becomes increasingly blurred.
In terms of abilities, Guren possesses considerable combat skills enhanced by his cursed gear Mahiru-no-Yo, a Black Demon series weapon that draws power eight times stronger than normal humans. He can skillfully use enchantments on spell tags and talismans to increase his cursed weapon's power. In his possessed state, he exhibits extraordinary speed and strength, able to overpower true vampires and demolish concrete structures with destructive energy attacks enveloped in demonic aura. His cursed gear can transform, changing from black to deep red when he taps into its full potential. His intelligence is rated highly, as he handles planning and command for successful missions. He is described as a genius who only appears once in a thousand years within the Ichinose family, but he tends to be cocky and sometimes underestimates his opponents.
