Power Progression

Stage / Realm / Level	Chapter	Notes
Earthbound clone	183	Only a clone reached Earth while the main body was held at the Moon. It rapidly grew by devouring divine power.
Seventh-tier true body	238	Sefar's normal true-body specification; it could affect a planet's surface but remained vulnerable to stellar power.
Eighth-tier threshold	238	Sefar surpasses the seventh tier and touches star-making power, gaining the ability to use concentrated energy attacks and ignore the special targeting of stellar power.

Background

The Harvest Star Vanguards descended upon Earth in the distant past and shattered the foundation supporting the gods' existence in the mortal realm. Their arrival began the decline of the Age of Gods, leaving most gods unable to descend in their true forms and forcing them to rely on possession, temporary vessels, or indirect methods of intervention. 30

One Vanguard's main body was blocked on the Moon by the Moon Cell, while a lower-level clone reached Earth. Even that clone devastated the planet's divine civilizations by absorbing the gods' power to evolve. Zeus united the Greek gods against it and survived defeat; the Norse gods escaped with a shed remnant, while Mesopotamian gods fled. 183

The Norse gods later turned part of that remnant into the World Tree. The artificial tree inherited the Vanguard's capacity to absorb external energy and regulate planetary civilization, allowing it to compensate for the loss of mystery and prolong the Norse Age of Gods. Its influence also produced white crystals—described as “Norse Divinity”—within the land's gods and living beings. 135

The remnant's power was not safely controlled. It continued corrupting the Nine Realms through the World Tree, turning Norse gods into its extensions. Thor's immense power, battle-driven growth, and eventual corruption all stemmed from the Harvest Star Vanguard known as Lucefa. 143 153 154

Appearance

Harvest Star Vanguards are usually described through Sefar/Seferu, the main body sealed within the Moon Cell. Their forms combine humanoid beauty with enormous mechanical scale and civilization-ending power. 237 238

• Pale, colossal humanoid “Giant God” body. 149 237
• Crystal cube-like structures embedded in the chest and palms. 237
• Long, slender limbs despite an overwhelmingly massive frame. 237
• At higher output, can enlarge toward a star-making scale. 238
• Their degraded humanized form is represented by Attila, who retains the Vanguard's underlying nature. 246 248

Operational Behavior

Harvest Star Vanguards act according to an instinctive function: the destruction and consumption of civilization. Sefar repeatedly labels civilization as “bad civilization,” reflecting an automatic hostile response rather than a conventional moral judgment. 237 247

Their behavior prioritizes efficiency. Sefar initially relies on close combat because it is more efficient below the eighth tier, then transitions to concentrated energy attacks after reaching a higher level. 238

Attila demonstrates that a Vanguard can develop beyond this instinct. Though she retains hostility toward civilization and fears natural planetary phenomena, she has become “human” and possesses an independent consciousness. 246 247

Abilities & Functions

Civilization and Energy Devouring

Harvest Star Vanguards consume energy and the concepts produced by civilizations, converting what they absorb into evolutionary power. 135 237

• Can absorb divine power and use it to rapidly strengthen themselves. 183
• Can consume external energy to expand their scale and sustain continued growth. 135
• Feed specifically on civilization concepts as well as raw energy. 237
• Their devouring ability can be countered by Rovi's Power of Domination when he controls Moon Cell authority. 237

Planetary Civilization Suppression

A Vanguard's presence undermines the foundations of divine civilization and drains the mystery sustaining an Age of Gods. 30 135

• The ancient invasion caused the long decline of Earth's Age of Gods. 30
• The World Tree replicated this function on a regional scale to maintain Norse divine rule. 135
• The residual power of a Vanguard can corrupt gods and transform them into extensions of its influence. 153

Evolution Through Conflict

Vanguard-derived entities can convert battle-related concepts into power. The Warrior Gods display a partial manifestation by turning pain into strength, while Thor's body converts combat against strong enemies into growth. 138 153

• Growth intensifies as the user suffers injury or confronts stronger opponents. 138 153
• This is only a partial inheritance when wielded by Norse gods; they do not possess every Vanguard attribute. 138 153
• At the eighth-tier threshold, Sefar gains the capacity for high-density energy attacks. 238

Natural Body

Attila's weakened, degenerated Vanguard state retains the skill Natural Body, giving her an exceptionally resilient physique. 247

• Makes physical restraint and escape difficult even for Rovi. 247
• Represents only a fraction of a full Vanguard's former strength. 248

Self-Mechanism

The Harvest Star Vanguard possesses a mental self-mechanism connected to Sefar's origin. Attila can unfold and control this consciousness-domain space. 246

• The mechanism is tied to Attila's ability to become fully free from Sefar's origin. 246
• Only Attila can control the mental domain opened by her Vanguard mechanism. 246

Relationships

• Sefar / Seferu / Sephalou — The principal Harvest Star Vanguard sealed within the Moon Cell; its main body seeks to escape and destroy Earth's civilization. 236 237
• Attila — A humanized, weakened form connected to Sefar's self-mechanism and origin; retains Vanguard traits while developing an independent self. 246 248
• Moon Cell — The lunar supercomputer that defeated or restrained the main body and sealed it on the Moon; it later becomes the site of Rovi's battle with Sefar. 201 236 237
• Rovi — Fought Sefar inside the Moon Cell by using Cronus's Power of Domination to seize Moon Cell authority; he intended to contain both the Moon Cell and the Vanguard within the Core of Chaos. 237 238
• Artemis — Contracted by the Moon Cell to prevent Sefar's escape; she planned to sacrifice herself in a lunar energy attack before Rovi intervened. 236 237
• Zeus — United the authority of the Greek gods against the ancient Vanguard invasion, but was defeated rather than killed. 126 183 236
• Odin — Used a Harvest Star Vanguard remnant to cultivate the World Tree and sustain the Nine Realms' Age of Gods. 149 153
• Thor — His body and extraordinary battle-growth ability originate from the Vanguard remnant known as Lucefa. 143 153 154
• Tamamo no Mae — A primordial sun god who was defeated by Sefar in the ancient era and still fears the Vanguard's presence. 182 248

Major Events

Ancient Invasion

A Harvest Star Vanguard entered the Earth-Moon system, with its main body held at the Moon and a clone descending to Earth. The clone's destruction of divine foundations initiated the decline of the Age of Gods. 30 183 236

Creation of the World Tree

The Norse gods acquired a remnant of the invading Vanguard and remade it into the World Tree, using its civilization-regulating and energy-absorbing properties to preserve their divine era. 135 149

Moon Cell Confrontation

Sefar awakens within its lunar prison and attempts to escape. Artemis holds it back under contract with the Moon Cell until Rovi takes her place, gains up to fifty-one percent Moon Cell authorization, and directly battles the Vanguard within the information world of the Moon Cell. 236 237

Attila's Manifestation

Attila manifests as a degraded Harvest Star Vanguard with only first-tier strength, yet her essence remains terrifying enough to frighten primordial gods such as Tamamo no Mae. 246 248

Trivia

• The Norse World Tree's hollow trunk and central cube resemble the Harvest Star Vanguard that invaded Earth. 135
• Sefar's seventh-tier form can be targeted by stellar power, but an eighth-tier Vanguard can resist that weakness. 238
• The Star Holy Sword previously defeated Sefar's Earthbound clone by transmitting the damage to its main body and briefly immobilizing it. 237
