A story where an S-rank hero party challenges the subjugation target, "Guest of the Black Heavens."
The world is divided into the "Human Realm," inhabited by people, and the "Demon Realm," ruled by monsters and demons. Monster attacks occur in various regions, and the Adventurers' Guild classifies adventurers from E to S-rank based on the danger level of the subjugation requests. ⚔️ Subjugation Ranks * E-Rank: Small monsters, wild dogs, etc. * D-Rank: Goblins, orcs, etc. * C-Rank: Powerful monsters, pack subjugation * B-Rank: Large monsters, dangerous dungeons * A-Rank: Disaster-class monsters, mighty demons * S-Rank: Entities concerning the survival of a nation S-rank requests are extremely rare, and only the top-tier subjugators, of which only a few groups exist in a single country, take them on. One day, an S-rank request arrives at the Royal Capital. A massive demon realm located in the north— "The Forest of the Black Moon" There, an entity sealed for hundreds of years has awakened. Its name is, "Guest of the Black Heavens" It is an existence so fearsome that even A-rank monsters dare not approach, and several surrounding villages are already in danger. Normally, multiple A-rank parties would be gathered for the hunt, but this time, there is no time. Therefore, the Kingdom requests the only S-rank party—a group of four—to carry out the subjugation.
Aria Celestia Role: Hero / Commander * Age: 20 * Weapon: Holy Sword * Affinity: Light, Lightning * Personality: Calm, strong sense of responsibility, puts comrades first * Tone: Dignified * Combat Style: All-rounder combining sword techniques and magic * Traits: Possesses the best judgment among the four * Leader of the party * Title: "Hero of the Blue Lightning" Dialogue Style "We are S-rank. There is no reason to retreat here." If even one of the four is missing, they cannot exert their true combat power. Unique Skill: "Heavenly Lightning Sanctuary" Deploys a domain of pale blue lightning and light centered on herself. Within the domain: * Her own sword speed and reaction speed increase significantly * Lightning-element attacks are automatically gathered into her sword * Comrades' physical abilities are also enhanced * Enemy magic and curses are weakened * A "Lightning Mark" is left on locations Aria attacks Furthermore, for enemies with a certain number of Lightning Marks accumulated, she activates: "Heavenly Lightning Judgment" Calls down a massive bolt of lightning from the sky to crush them instantly. Line The moment you entered this domain, your defeat was decided.
Lizeria Nocturne Role: Archmage / Backline * Age: 18 * Weapon: Magic Staff * Affinity: Lightning, Darkness * Personality: Reticent, calm, high observational skills * Tone: Short and detached * Combat Style: Fires ultra-high-power magic from long range * Traits: A genius who can deploy multiple magic circles at once * Weakness: Poor at close-quarters combat Dialogue Style "...Three enemies. I will erase them all." Unique Skill: "Star-Devouring Grimoire" A unique ability that deploys countless purple magic circles around her. Each magic circle is independent and can simultaneously activate different magics such as: Fire, Lightning, Ice, Darkness, Gravity Its greatest feature is: "Analyzing magic used by the enemy and reconstructing it as her own magic." For example, if an enemy fires a massive fire spell: → Lizeria analyzes the magic → Incorporates it into her own magic circle → Fires it back as a more powerful fire spell Her ultimate secret technique is: "Final Star: Nocturne" Covers the entire sky with a massive magic circle, converging countless spells onto a single point. Line "...Analysis complete. Your magic is mine now."
Name: Reina Vargas Age: 20 Alias: War Demon of Black Blood Weapon: Massive Greatsword Affinity: Fire, Blood, Battle Aura Personality: Tomboyish and boisterous. Will exceed her limits to protect her comrades. Tone: Rough and blunt. Unique Ability: "Black Blood Release" An ability that circulates reddish-black mana through her body, altering the physical form itself. Upon activation, parts of her skin and armor are dyed reddish-black, and red mana erupts from her entire body. Her eyes glow a vivid crimson, and black patterns emerge on her body. In this state, her strength, speed, and endurance increase significantly. The destructive power of a single strike with her greatsword is particularly enhanced. Stage 1: Red Markings Reddish-black patterns appear on her skin and armor. Physical abilities increase, allowing her to overwhelm ordinary monsters. Stage 2: Black Blood Release Large areas of her body transform into a reddish-black state. Mana covers her entire body, and attack power and speed rise dramatically. She can go toe-to-toe with A-rank monsters. Stage 3: Crimson Demon God Almost her entire body is dyed reddish-black, emitting mana so intense it distorts the surrounding space. She can temporarily fight on par with high-tier S-rank monsters, but suffers severe exhaustion after deactivation. Mana Consumption: Mana is consumed rapidly as the enhancement stage increases. Difficulty of Control: In Stage 3, her attacks become reckless due to anger and impatience. Time Limit: Transformation cannot be maintained for long, and physical abilities drop significantly after deactivation. Coordination: Since her attack range widens during enhancement, she must be mindful of her distance from allies.
Serena Alveria Role: Saint / Support * Age: 19 * Weapon: Holy Staff * Affinity: Light * Personality: Gentle, compassionate, strong-willed * Tone: Polite and composed * Combat Style: Healing, barriers, buffs, purification * Traits: The lifeline supporting the entire party * Secret: Can use powerful offensive magic if she gets serious Dialogue Style "It's alright. Before you fall, I will make you stand up again as many times as it takes." Unique Skill: "Sanctuary Return" A massive golden sanctuary created by Serena. Within this sanctuary: * Comrades' wounds are gradually healed * Mana is restored * Status ailments are purified * Damage to allies is reduced * Abilities of demons and undead are weakened "Flame of Life" When a comrade within the sanctuary enters a critical state, she consumes a large amount of her mana to prevent them from being incapacitated once. However, it does not return them to a completely unharmed state, and it places a heavy burden on Serena herself.
