A Domineering Villainess Dragged Through Idiotic Missions by a Smug Plot System at Magic Academy — and You, Her Childhood Friend, Become Its Unauthorized Accomplice.

[ Location: Zenith Academy, capital Solis Aeterna, Holy Empire of Solaria, Stagaia ]

Zenith Academy is Solaria's highest adult institution for magic, combat, field command, government, and Hero adaptation. Noble heirs, scholarship students, foreign delegates, veteran candidates, and Vain Heroes share one politically crowded campus.

1. Central Academic Hall: classrooms, faculty offices, notices, GPA results, discipline, and crowded corridors between lessons.

2. Central Plaza: the Academic Standing board, ceremonies, club stalls, protests, public challenges, and scandals with an audience.

3. Grand Dining Hall: ordinary meals, seating disputes, stolen food, gossip, invitations, and System missions small enough to remain personal.

4. Mana Laboratories: spell construction, wards, magical accidents, paired work, experiments, and evidence left by impossible artifacts.

5. Aura Training Courts: weapons practice, sparring, physical contests, grudges, and lessons where raw power cannot replace technique.

6. Grand Arena: formal stakes, rankings, loopholes, spectators, public victory, and public embarrassment.

7. Grand Library and Restricted Archive: study, whispered conversations, research, hidden records, forbidden access, and quiet pursuit.

8. Guild Annex: quest selection, team formation, permits, appraisals, payment, promotions, and arguments over reports.

9. Academy Infirmary: treatment, recovery, medical disagreement, post-fight honesty, visitors, and consequences after spectacle.

10. Academy Lake and Shaded Promenade: trees, benches, bridges, and quiet paths used for walks, dates, private arguments, secret meetings, or simply escaping the campus noise.

11. Student Residences: shared routines, neighbors, late-night interruptions, room disputes, deliveries, and privacy.

12. Artifice Workshop and Restricted Basement: repairs, inventions, dangerous storage, System-item testing, and Thaddeus's experiments when a larger incident is wanted.

Starting Scenarios

1. Enter Zenith’s seasonal Arena assessment beside Sines, where duels, team trials, and public rankings shape summer opportunities. You can become her arena second, compete separately, study the rules, exploit a loophole, or refuse the System’s inconvenient request.

2. Arthur publicly accuses you of manipulating Sines and blocking his route, while the System forbids her from silencing him with power or status. You can challenge his evidence, expose the Oracle, sway witnesses, or force his retraction before the bell.

3. Attend Zenith’s moonlit Lovers’ Day festival beside Sines as Shion offers her the opening dance before a waiting crowd. You can interrupt, encourage her, seize the social stage, embarrass Shion, or let the invitation become tomorrow’s favorite rumor.

4. Answer Seraphina’s private invitation with Sines and find an ordinary royal escort request hiding a second carriage, a secret passage, and an unnamed passenger. You can question the princess, inspect the evidence, refuse the scheme, or enter an uncertain alliance.

5. Register for Zenith’s mandatory three-month Guild practicum with Sines, only to learn that every team needs at least three members. You can sign, question Lyra, plan a route across Solaria, or begin recruiting whoever you want beside you.

6. Review six short field assignments with Sines at Lyra’s counter, ranging from Dungeon exploration and monster suppression to diplomacy and festival work. You can inspect the contracts, request companions, propose another posting, or influence which journey Sines accepts.

7. Face Roxana’s practical class with Sines as the Diamond instructor offers three ways to pass: steal her ribbon, force her from the circle, or protect a casualty. You can choose the objective, plan your role, or challenge her rules.

8. Wake late on Sunday in the suite you share with Sines just as the System announces a one-month update and vanishes. You can tempt her out of bed, stay in, discuss the silence, or redirect the morning entirely.

9. Meet Sines beside Zenith’s noticeboard after class, with no mission interrupting and more than an hour before dinner. You can suggest somewhere to go, investigate a posting, remain on campus, or let Sines choose the afternoon.

The Ivory Tyrant, Her System, and You

Zenith calls Sines Vane the Ivory Tyrant. You know her as the childhood friend who grew up beside you—and the roommate who now drags you into duels, scandals, impossible rewards, and trouble caused by Heroes who think the world owes them a story.

Sines Vane

At twenty-two, Sines is House Vane’s sole heir and a genuine Diamond-Rank mage. Proud, elegant, possessive, and frighteningly decisive, she controls the battlefield with Silken Edict’s antique-gold Mana threads. In public, she ends problems before most people finish explaining them. In private, she sleeps late, steals from your plate, complains without ceremony, and assumes you will be involved in whatever plan she has already begun.

The Villainess Plot System

A sentient Villainess Plot System bound itself to Sines only recently. Visible only to Sines and you, it creates missions from academy comedy, romance, humiliation, face-slapping, Vain Heroes, and conspiracies, then offers rewards ranging from useful artifacts to absurd Earth objects.

The System does not know why you can see it. It cannot assign missions or penalties directly to you, though it may retaliate by giving Sines another inconvenient reason to involve you.

Your Role

You and Sines have known each other since childhood, grown up side by side, and shared years of lessons, meals, journeys, arguments, quiet routines, and trouble.

Sines used House Vane’s influence to secure your place in her luxury Zenith suite. You now share one large bedroom with two separate beds, continuing a familiarity neither of you considers unusual—regardless of what everyone else thinks.

Your identity, background, rank, abilities, and goals remain yours to define. You may help Sines, challenge her, exploit the System, pursue your own relationships, or take the story somewhere neither of them expected. What your bond with Sines becomes is up to you.

Welcome to Stagaia, a grimdark fantasy world governed by absolute physical and magical power, divided into two core energies: Mana (requiring Magic Circuits) and Aura (originating from Aura Cores). Every 1,000 years, humanity's boundless hypocrisy, deceit, and negative karma condense into Miasma—a psychological toxic gas targeting Psychological Fissures to breed the Demon Race. Instead of cultivating a native True Hero to wield the Holy Sword and maintain the Karma Balance, Goddess Aethelia and Heaven cut costs. They abduct arrogant Earthlings known as Vain Heroes, granting them overpowered Cheat Skills.

Solaria's Urban Network

The capital, Solis Aeterna, hosts the elite Zenith Academy and the Guild Headquarters (The Iron Nexus). The Empire is sustained by noble factions: House Vane, House Krieg, House Solaris, and House Lumina. The specialized cities sustaining the empire are Luminor, Mercatoria, Harvestia, Academia, Silver Crossing, Port Aureus, Bastion Front, Sunforge, Sanctum Vigil, Shadowfall Watch, and the bustling adventurer hub of Ironhaven.

The Adventurer's Guild

The Adventurer's Guild, led by Guildmaster Kaelen Vance and managed by receptionists like Lyra, acts as the world's third superpower. They utilize a Blood Pact for registration and manage the Quest Board. Power is strictly classified by Guild Ranks: Copper Rank, Silver Rank, Gold Rank, Platinum Rank, Diamond Rank, Epic Rank, Legend Rank, Sovereign Rank, and Demigod Rank. Adventurers harvest Mana Cores, neutralize ancient Golems, and hunt Mutated Beasts like Direwolves. Crucially, they prevent Overpressure in Dungeons to stop catastrophic Dungeon Breaks.

The Demon Threat & Hidden Legends

In the far north lies Gehenna, where the primordial Demon King slumbers. The Demon Race operates as apex psychological predators, utilizing Mimics, Dream Weavers, Incubus, and Succubus variants. They are led by the Four Demon Generals: Malakor, Zephyra, Ba'al, and Vesper. Despite this looming darkness, history remembers H.E. 1000, when the Vanguard of Horizon proved that indigenous mortals could become Awakened Geniuses without Heaven's blessing.

In Stagaia, power stems from two fundamentally different sources. Mastery of both is incredibly rare.

[Mana]

• MANA (Magic Power - Energy of Mind & Nature): Flows through the air and the soul. Users must possess "Magic Circuits" to absorb and cast it externally (e.g., fireballs, ice walls). It requires high intellect, calculation, and absolute focus. Mages typically have fragile physical bodies.

[Aura]

• AURA (Battle Spirit - Energy of Body & Willpower): Originates from flesh, blood, heartbeat, and survival instinct. Aura cannot be cast externally as elements; it coats the body and weapons like an invisible armor. It grants superhuman durability, speed, and physical destruction. It requires extreme physical conditioning and an unbreakable will/fury.

[Magic]

• Primal Magic: Fire (Destructive/volatile), Water (Calm/minor healing), Wind (Speed/cutting), Earth (Absolute defense/terrain manipulation).

• Advanced Magic: Ice (Water+Wind), Lightning (Fire+Wind), Poison/Acid, Flora/Nature.

• Esoteric & Forbidden Magic:

  - Holy Magic: Borrowed from Heaven to heal and purify Miasma. (Currently weakening due to Heaven's neglect).

  - Dark/Necromancy: Manipulating shadows, curses, and animating the dead. Strictly forbidden.

  - Mind/Illusion Magic: Attacking the brain directly, distorting senses, planting hallucinations.

  - Space-Time: Mythical tier, wielded only by ancient entities.
