Because the universe was violently stitched together before its temporal loop could be finalized, Omiro-cho is littered with reality tears known as Old-World Anomalies, or "Fissures."
To a normal civilian, these are entirely invisible. But to Passengers and awakened Stand Users, they appear as literal, jagged cracks suspended in the middle of the air, or etched into the sides of buildings and the pavement. Passengers inexplicably feel a gravitational pull toward these pockets of the dead universe.
These Fissures act as gateways to isolated fragments of the previous universe. If an awakened individual touches a Fissure, they are instantly drawn inside.
Safe Havens (Lore & Clues): Some Fissures are entirely safe. They might manifest as an empty, dimly lit movie theater or a dusty library, serving as a quiet space where players can uncover lore, find clues about the original universe, or piece together the mystery of Omiro-cho.
Hostile Pockets: Other Fissures are dangerous, manifesting as bone-chilling caves, run-down houses, or distorted city streets. Once inside a hostile pocket, the Fissure seals behind the player. They cannot leave until the entities within are defeated.
Faction Scouting: Factions within Omiro-cho often have dedicated scout teams actively mapping the city. If players ally with a faction, they can receive coordinates to newly formed Fissures as quest objectives.
The GM must provide clear visual cues regarding the danger level of a Fissure before a player enters it, allowing them to gauge if they are appropriately leveled for the encounter:
Safe/Lore Fissures: Emit a gentle, pale light or a soft, humming vibration.
Low-to-Mid Threat Fissures: Leak a faint, hissing static, or a thin, localized mist spills from the crack.
Lethal Threat Fissures: Bleed viscous, dark matter or violently crackle with crimson, gravitational energy. The crack itself may appear to be actively splintering wider.
The hostile entities trapped within these Anomalies are known as "Sinners."
During the events of the original timeline, Enrico Pucci sacrificed the souls of 36 extreme sinners to evolve his Stand. Because the universe collapsed, these sacrificed souls were left without a home reality, becoming trapped in cosmic limbo.
They manifest as hostile, faceless entities made of crackling static and spiritual energy. They wander the hostile Fissures and must be destroyed for the Anomaly to collapse and release the trapped players.
Successfully clearing or sealing a Fissure yields varying rewards:
Rescue: Sometimes, an oblivious civilian or an unawakened Passenger accidentally stumbles into a Fissure. Rescuing them yields high favor.
Old-World Bounties: Players can find remnants of the old world inside, directly translating into tangible wealth, such as finding thick stacks of $1 bills or straightforward $10 and $100 denominations hidden within the pocket.
Faction Payouts: Allied factions will often provide resources or monetary compensation as a bounty for successfully sealing a dangerous tear in the city.
Hayato is the central antagonist of the campaign. Unlike the naive Passengers, Hayato possesses a deep understanding of the texts detailing DIO's original plan and the true nature of the universe's collapse.
He knows how to loosely manipulate these Old-World Anomalies and frequently weaponizes them to trap or study his victims.
Heaven's Will: Hayato believes that the new reality must be preserved at all costs, and that Passengers—who inherently carry the "rot" of the old world—are a threat to existence. He manipulates and systematically executes them, viewing his actions as a holy cleansing.
The GM must allow the players to believe their ultimate goal is to "fix" the universe by stitching these Anomalies back together to restore their old lives.
However, the true endgame revelation—discovered only when confronting, defeating, losing to, or even joining Hayato—is that restoring the old universe is impossible without committing mass genocide on the current reality.
The ultimate narrative climax of this campaign is Acceptance. The players must accept their new reality, choosing to protect their new home rather than stubbornly destroying it to chase a dead past.
