Shien's Chapter: Fanaticism

Released as the third and final installment of Death Note: New Generation, the chapter sits inside the broader live-action Death Note film line. Where earlier entries followed other figures, this one fixes entirely on Yuki Shien, unpacking the forces that drive him to take up the notebook. It premiered on Hulu Japan on September 30, 2016, arriving directly after the preceding chapter, Ryuzaki's Chapter: Dying Wish.

The chapter opens inside Shien's memories. As a boy he watched a man named Namekawa slaughter his relatives, an attack he barely survived. A ruling of mental incompetence set the killer free, and the orphaned child grew up in a group home, jolted awake by recurring dreams of his own death. Everything shifts when Kira strikes Namekawa down. Shien becomes a believer, and once the unseen judge falls silent, the grown survivor pours himself into hacking, branding himself a digital vigilante working on the world's behalf. One night, mid-intrusion into some network, a notebook tumbles into his apartment.

Shien chooses his first targets with care: two men who butchered a household a decade earlier and walked free. Kazutoshi Namaki remains an unrepentant addict, while his former accomplice has buried the past. That second man, once called Kunugida, now answers to Amazawa, scrubs toilets for wages, and shares a home with the woman he loves. When she reveals a pregnancy and proposes marriage, he crumbles, certain he has no right to happiness, until she insists the man named Kunugida is gone.

Namaki resurfaces at Amazawa's workplace, dangling an invitation to something illicit and thrilling. Rebuffed, he hints at harm to Amazawa's family and promises to return. Shien inks Namaki's name, and as Amazawa walks off, he glances back to find his tormentor crumpled on the ground, felled by sudden cardiac arrest. The reprieve lets Amazawa rest easy, and by morning he asks for his partner's hand, the pair arranging a celebratory dinner.

Shien is not finished. He corners Amazawa over a toilet bowl, greets him by his abandoned surname, and insists a new identity can never wash away guilt. Amazawa swears the crime has tormented him and that remorse never left, but Shien fixates on a single fact: a girl of seven died by this man's hand. Watching through a security feed, Shien records the name Taichi Kunugida, yet nothing happens. Only when he switches to Taichi Amazawa does the heart stop. At home that evening, the expectant mother thumbs through magazines for newborns and keeps glancing at the clock as the hour grows late.

From there Shien settles into a daily ritual of condemnation, styling himself the reborn Kira. The episode ends as a bulletin reaches him: bodies are collapsing in public, and authorities have summoned a special countermeasure unit built to confront the notebook. Digging online, he finds a cryptic post, traces its author, and surfaces the name Sakura Aoi. Convinced he is Kira's appointed courier, charged with gathering every notebook scattered across the globe, Shien pockets his own and tells Ryuk he is heading out. The shinigami materializes with a single amused verdict, Interesting.

As the closing entry of the three-part Death Note: New Generation, the chapter premiered on Hulu Japan on September 30, 2016, following Ryuzaki's Chapter: Dying Wish, and belongs to the wider live-action Death Note film line. Masaki Suda takes the role of Yuki Shien, while Tomoya Nakamura plays the guilt-ridden Taichi Amazawa. The finale leaves Shien setting out to track down the others touched by the scattered notebooks.
