Description
Gen'ichi Norose is the president of the technology corporation N.O.Z.O.M.I. and serves as the central antagonist of the narrative. A man in his early forties with grey hair, he presents the composed appearance of a typical middle-aged businessman dressed in a suit and tie, though his demeanor can shift to reveal a more dangerous and crazed intensity. His background is rooted in medicine; he was formerly a doctor at AH Tokyo General Hospital, where he conducted inhumane experiments. His talents were eventually recognized, leading to his promotion as the CEO of N.O.Z.O.M.I., the very company that owned the hospital where he once worked.

The core of Norose's personality is a profound contradiction shaped by his long history as a Gigalomaniac, one who has been awakened to his powers since childhood. Having witnessed the darkest aspects of humanity for a much longer period than others of his kind, he became deeply bitter, pessimistic, and disillusioned with the world and the selfishness of people. This despair twisted him into a cruel, sadistic, and distrustful individual. Yet, paradoxically, he still clings to a noble ideal deep within: the genuine desire to create a true utopia for humanity, a place where people can be truly happy. This combination of high-minded goals and utterly ruthless, often evil methods transforms him into a dangerous figure whose noble intentions have been completely corrupted by his willingness to do anything to achieve them.

His motivations are a direct rebellion against the shadowy Committee of 300 and their plans for a dystopian "Human Cultivation Project." Norose disagrees with their vision, which would involve genocide and global control, seeking instead to create his own ideal world. To this end, he spearheads Project Noah and the development of the Noah II device, an artificial system designed to replicate the powers of a Gigalomaniac. His role as the main antagonist is cemented by his ruthless methods, which include orchestrating the gruesome New Gen Murders to break the protagonist's spirit, kidnapping key characters to use as bait, and conducting horrific experiments on innocent people such as his test subject, a woman forced to bear a delusional baby until she lost her mind.

In his pursuit of this goal, Norose engages in a complex web of key relationships. He forges a temporary alliance with Kouzou Inohana of the Meiwa Party and Chairman Yuudai Kuramochi of the Cosmic Church of the Divine Light to betray the Committee of 300. However, their visions for the new world inevitably clash, as his co-conspirators merely seek political power or mass conversion. Ultimately, Norose views them as obstacles and uses the power of Noah II to trick them into killing each other. His primary opposition comes from the young Gigalomaniac Takumi Nishijou, who is manipulated by the Committee of 300 into becoming the force that can destroy Norose and the Noah II device.

As a character, Norose is portrayed differently depending on the adaptation. In the original visual novel, he is a more complex anti-villain, whose tragic past and noble, if twisted, ideals make him a counterpart to the reluctant anti-hero protagonist. In the non-canonical anime adaptation, this complexity is stripped away, and he is simplified into a more stereotypical, power-mad psychopath driven by jealousy and a simple desire for world domination. His development arc typically culminates in a final confrontation with a fully awakened Takumi, where he is ultimately defeated and killed, and the Noah II device is destroyed, stopping his plan for forced global utopia.

Regarding his notable abilities, Norose is himself a powerful, naturally awakened Gigalomaniac. He is also intimately connected to the Noah II device, using it to project powerful delusions, torture his enemies, and even cause destructive earthquakes. He manifests a unique DI-sword, the physical manifestation of a Gigalomaniac's power, which is distinct from others in the story. His sword is notably large, towering over him, and is colored black with golden features, contrasting sharply with the more common lavender and pink blades seen elsewhere. It is shaped like a massive pair of scissors, reflecting his imposing and cruel nature.
