Description
Hasegawa serves as the primary antagonist in the story, holding the position of despotic leader of the Red Imperial Army. His background is deeply rooted in scientific ambition, as he functions as an Evilutionary Biologist who believes in engineering the human race to achieve a new level of existence. He first appears in a futuristic, post-apocalyptic setting where the Red Imperial Army exerts absolute control over what remains of society.
Hasegawa possesses a personality defined by cold calculation, absolute ruthlessness, and a complete lack of empathy for human life. He views people not as individuals but as raw materials for his experiments, discarding those he deems failures without any sign of remorse. The introduction to his character demonstrates this cruelty explicitly, as he personally disposes of hundreds of test subjects he considers failures by dropping them one by one down a chute leading into a grinder that reduces them to a bloody pulp. He maintains an air of intellectual superiority, treating even his enemies with condescending fascination rather than fear or respect.
His primary motivation is the creation of a perfect specimen of soldiers to enforce his dictatorship and reshape the world according to his vision. To achieve this goal, Hasegawa has dedicated himself to studying immortality and genetic manipulation. He has monitored the immortal protagonist Kuro for approximately one thousand years, patiently waiting for the opportunity to capture him and analyze his unique biological properties. Hasegawa sees Kuro not as an enemy to be destroyed but as the ultimate research subject, a living puzzle that holds the key to his plans for human evolution.
Within the story, Hasegawa commands the forces of the Red Imperial Army, orchestrating raids and military operations designed to capture Kuro and eliminate anyone who stands in the way. He is responsible for countless civilian casualties, showing no concern for the lives lost in his pursuit of scientific advancement. His laboratory serves as the central hub of his operations, where he conducts mass blood transfusions using Kuromitsu's blood on human test subjects, though most subjects die from the incompatibility. Hasegawa also works to neutralize opposition to his regime, launching repeated attacks that result in the deaths of resistance members, including the rebel leader Saniwa and Kuro's friend Kuon.
In terms of key relationships, Hasegawa views Kuro as his greatest prize and the ultimate test subject. He has spent centuries studying Kuro's existence from afar, collecting data and waiting for the right moment to strike. His relationship with Kuon is particularly disturbing, as Hasegawa created Kuon in his laboratory using genetic material derived from Kuro's blood. This makes Kuon both a creation and a tool in Hasegawa's experiments, a living being manufactured for the sole purpose of advancing his research. Hasegawa also has connections to Kuromitsu, whose blood holds the secret to immortality, and he has worked alongside her at some points in the past toward shared research goals.
The character undergoes notable development as the story progresses toward its climax. When he finally captures Kuro, Hasegawa reveals the depth of his knowledge about the protagonist's past, showing Kuro recorded footage of events the immortal had forgotten and explaining the true nature of his own existence. In a final act of desperation to achieve his goal of perfection, Hasegawa injects himself with a super serum of his own creation, transforming his body into a literal monster to confront Kuro directly. This transformation represents the culmination of his philosophy, the rejection of human limitations in favor of something greater, though it ultimately becomes his downfall when Kuro kills him in their final battle.
Hasegawa possesses several notable abilities that make him a formidable antagonist. His primary strength lies in his scientific genius, allowing him to manipulate genetics, create enhanced soldiers, and develop serums that grant superhuman capabilities. He commands the full military resources of the Red Imperial Army, giving him access to advanced technology, weapons, and a loyal fighting force. During combat, he demonstrates tactical cunning, such as using Amazonian snake venom to temporarily blind Kuro during their confrontation. After his transformation, Hasegawa gains monstrous physical abilities that allow him to brutalize even an immortal being like Kuro, though this power comes at the cost of his human form and presumably his sanity.
