Description
Nagare Hisui is the Fifth Green King and the leader of the Green Clan, known as JUNGLE. As the primary antagonist of the second season, he seeks to release the power of the Dresden Slate to all of humanity, believing that a world where everyone possesses power will trigger a global evolution. His vision is one of freedom and natural selection, and he pursues this goal with relentless determination.

Born into a family that used highly formal and restrained speech, Nagare experienced a traumatic event during his childhood: the Kagutsu Crater Incident. While watching two suspended Swords of Damocles with friends, he predicted that the red sword would fall. Moments later, it crashed, killing everyone around him. Nagare survived but was struck by debris that pierced his chest, destroying his heart. He was found amidst the wreckage by Tenkei Iwafune, and at that moment his power as the Green King awakened, his Aura substituting for his lost heart. The incident left him permanently disabled, requiring the use of a wheelchair. He later challenged the Gold King but was defeated, after which he became more reclusive and began operating primarily through his clan.

Nagare's personality blends a cold, manipulative strategist with an idealistic visionary and a childlike sense of wonder. He treats many of his subordinates as expendable tools and does not hesitate to order lethal actions that may harm them, yet he shows genuine warmth and familiarity toward his three J‑Rank clansmen: Tenkei Iwafune, Yukari Mishakuji, and Sukuna Gojo. He sees Tenkei as a father figure, allows Sukuna to indulge in video games, and entrusts major operations to Yukari. His speech is often honest and direct, even with enemies, and he enjoys framing his ambitions as though he were playing a game. He holds the Silver King, Adolf K. Weismann, in the highest regard and respects him above all other Kings. At the same time, he harbors no malice in his belief that unleashing the Slate would lead to a better world, even if it brings chaos and natural selection.

In the story, Nagare is the mastermind behind the war that drives the plot. He exploits the Colorless King to sow discord, abducts Anna Kushina to use her divination powers to locate the Silver King, and orders his J‑Ranks to attack members of the Red, Blue, and Silver Clans. His ultimate objective is to gain control of the Dresden Slate, a task made easier after the death of the Gold King. Throughout the series, he maneuvers against Reisi Munakata’s Scepter 4, the HOMRA clan, and Yashiro Isana’s Silver Clan, culminating in a massive assault on the Vanhallen building. Despite his physical frailty, he is a formidable force.

Key relationships include his deep bond with the Gray King, Seigo Ōtari, who acts as his protector and guardian. He communicates frequently through a green parrot named Kotosaka, which serves as his eyes, ears, and voice when he cannot be physically present. His J‑Ranks—Yukari, Sukuna, and Tenkei—are his most trusted subordinates, and he treats them with a familial closeness that contrasts with his treatment of lesser clan members.

Nagare’s development is driven by his singular pursuit of the Dresden Slate. As the series progresses, his powers surge after his Sword of Damocles fully manifests, and his appearance transforms: his hair turns brilliant white, his left eye glows green, and his attire shifts to flowing white robes. After the destruction of the Slate, his hair and clothing return to their original dark colors. He ultimately fails in his plan when the Silver King and his allies unite to stop him, and he is defeated.

Nagare’s abilities are rooted in the Green King’s power of change and transformation. He can alter the laws of matter, allowing him to pass through solid objects, enhance his physical capabilities to superhuman levels, and channel raw electrical and green energy through his aura. He can project his consciousness into Kotosaka, using the bird as a remote medium for communication and observation. His physical body, sustained by his Aura in place of his missing heart, is extremely frail but can be pushed beyond normal limits when he unleashes his full strength, enabling him to rival even the Gold King in combat. However, he cannot maintain that level of power for prolonged periods.
