Power Systems

The world of The Last Genesis runs on a unified combat framework. The core pillars and exclusive evolutions are as follows.

Will (意志 / Ishi)

The spiritual blueprint of a legendary consciousness passed to a living host. A Will carries memory, personality, and purpose, reshaping the host’s destiny.

Seiki (聖気)

The sacred life energy of existence that responds to emotion and intent. When a person inherits a Will, their Seiki evolves to mirror that Will’s nature.

Seiki Resonance (聖気共鳴)

The amplification that occurs when two or more Seiki flows synchronize in emotion and rhythm. Resonance is felt, not learned, and multiplies combined power.

Ketsugo (結合)

The sacred fusion between host and Will. Partial Ketsugo grants advanced strength and techniques. Complete Ketsugo risks erasing individuality as the Will fully incarnates.

Exclusive Evolutions

• Genesis Awakening – A rare evolution where a host’s Will surges into a new state, rewriting what their Seiki can do. Hajime’s power of the First Man manifests through this.
• Eclipse Ascension – A hybrid evolution born from combined Wills. Rei’s union of Uriel and Azazel pushes his Seiki into a radiant-dark form that threatens his mind and body.

Elite Groups & Secret Orders

These are the major named forces operating above ordinary armies, as recorded in the codex.

The Twelve Pillars

An elite order of disciples bound to apostolic Wills such as Peter, John, James, and others. Each Pillar carries a distinct title and function, acting as living doctrines of faith, doubt, mercy, and zeal.

The Five Commanders

The supreme military leaders of the five great nations, each wielding a legendary Will and directing entire armies in the wars to come.

The Fifteen Lords

The high lords of the Five Great Nations, each ruling a sector of power and bearing Wills such as Michael, Gabriel, Raphael, Eve, Noah, Judas, Cain, Nebuchadnezzar II, David, Joshua, Deborah, Samael, Asmodeus, and Belial.

The Forsakers

A nomadic band of outcasts whose members have rejected conventional allegiance. Their choices and Wills place them at odds with every major faction.

The Daughters of Ruin

A feared cadre of women tied to catastrophic Wills. Their presence on the battlefield is synonymous with devastation and moral collapse.

The Grigori Eight

Inverted Watchers who bear fallen versions of archangelic power. Their existence challenges the balance between Heaven, Hell, and humanity.

Apocalyptic Entities

The codex identifies two Omega-Primordial beings whose awakening marks the unsealing of the Seventh Seal.

Abaddon

Abaddon embodies destruction without purpose. When this entity moves, Seiki recoils and reality itself feels unstable. Abaddon is tied directly to the Seventh Seal Demon mentioned in the series synopsis.

The Ashen King

The Ashen King embodies hope without light. Known as the Burned Heir, this entity carries a presence of tragic finality. The Ashen King stands at the center of the series’ ultimate question about humanity’s free will and the end of the world.
