Kaul Hiloshudon, known as Hilo, is the Pillar and supreme leader of the No Peak clan. Forced into a cold "Slow War" against the rival Mountain clan, he balances the brutal traditions of his Green Bone heritage with the demands of an evolving, modernized world. He oversees illegal operations and corporate developments while trying to secure a future for his children. He is highly protective of his family, though the massive responsibilities of leadership frequently force him to make emotionally devastating choices.

Ayt Madashi is the leading Pillar of the rival Mountain clan. Driven by the childhood trauma of losing her family to foreign occupiers, she focuses entirely on unifying Kekon's Green Bones under her absolute control to resist outside influence. She relies on long-term political manipulation, economic warfare, and international smuggling alliances to financially starve No Peak. She trusts almost no one, keeping even her own family members at a calculated distance.

Shae serves as the Weather Man of the No Peak clan, directing their intelligence, business operations, and political strategy. A lead strategist, she recognizes that the clan's survival depends on mastering international finance and public relations rather than relying solely on street-level combat. She lobbies foreign governments to decriminalize jade and manages corporate acquisitions to secure the Kaul family's future.

Wen is Hilo's wife and a key strategic partner in the No Peak clan. As a stone-eye—someone biologically incapable of wielding jade—she moves through the Green Bone hierarchy as an outsider, cultivating alternative forms of power through public relations and media influence. She funds film studios and shapes international narratives to modernize the clan's image, proving that non-martial intelligence is essential for victory.

Anden is the adopted multiracial cousin of the Kaul family who rejected the violent life of a Fist to become a medical doctor. He travels abroad to Espenia to advocate for the legalization of jade in medicine, frequently acting as a reluctant bridge between Kekon and the outside world. He struggles with his duty to the clan, knowing his family often needs him to use his strong jade abilities in ways that contradict his healing profession.

Niko is the son of the deceased former Pillar Kaul Lan, now adopted and raised as Hilo's heir. He is a quiet, intellectual young man who bristles against the heavy expectations of his lineage and the violent traditions of the Green Bone world. Seeking independence, he looks for opportunities outside the clan structure, leading to significant generational conflict with his adoptive father.

Jaya is the fierce and ambitious daughter of Hilo and Wen. Unlike her brother Niko, she fully embraces the martial, aggressive aspects of Green Bone culture and demonstrates strong abilities with jade. She views her gender not as a limitation but as a unique advantage in her quest to climb the ranks of No Peak's military hierarchy.

Ru is the idealistic, good-hearted son of Hilo and Wen. Like his mother, he is a stone-eye, biologically excluded from the world of jade-wielding warriors. Despite this, he is raised with the traditional values and honor codes of the Kaul family, leaving him to survive in a violent society that both reveres his lineage and marginalizes his lack of abilities.

Maik Tar is a deeply committed Green Bone who serves as Hilo's Pillarman and chief enforcer. His identity is entirely consumed by his role as the clan's most lethal instrument, exacting brutal retribution against No Peak's enemies. The psychological toll of continuous violence threatens his sanity, pushing him toward the dangerous edge of overexposure known as a "green turning black."

Woon is a steadfast, quietly competent Green Bone who serves as a professional and emotional anchor within No Peak. Defined by his deep sense of duty, he acts as a trusted advisor and stabilizing force during the clan's chaotic political maneuvering. His relationship with Shae evolves from a professional partnership into a marriage, providing her with steadfast counsel.

Lott Jin is the capable and pragmatic First Fist of the No Peak clan. Rising through the ranks based on merit and hard work rather than family lineage, he represents a modern Green Bone warrior. He provides stability and tactical leadership to the clan's street soldiers, maintaining a strong moral center during periods of escalating violence.

Known as the "Bad Keck," Jon Remi is a brash, Keko-Espenian gangster operating in Resville. He commodifies Green Bone culture, adopting the power of jade while rejecting the traditional code of honor to build a lucrative criminal syndicate. He is an unpredictable opportunist who views the clans' rivalry purely as a chance for financial gain.

Jim Sunto is an ex-Espenian Navy Angel who views jade abilities as a marketable asset rather than a sacred birthright. He founds the private military company Ganlu Solutions International (GSI) to train corporate soldiers for foreign governments. His pragmatic, profit-driven approach to warfare frequently puts him at odds with traditionalist Kekonese leaders.

Bero is a clanless man harboring deep resentment toward the Green Bone establishment. Desperate for significance and power, he involves himself with the Clanless Future Movement and acts as an informant for foreign intelligence. He is a perpetual outsider driven by self-interest and a desire to dismantle the structures that exclude him.

Koben Atosho, often called Ato, is the charismatic nephew of Ayt Mada and the heir to the Mountain clan. Groomed as a public figurehead, he is initially utilized as a political tool by his ambitious aunt. He represents a new generation of leadership that relies heavily on media optics and public relations to project power and influence.
