The Four Elder Vampires' Sealing Conflict with the Seven Green-eyed Vampires

The Four Elder Vampires' Sealing Conflict with the Seven Green-eyed Vampires is the foundational supernatural conflict behind the castle’s instability. The Four Elder Vampires confront seven other vampires associated with green eyes, bodily possession, hypnosis, and a neighboring other world. Their effort to protect the castle does not simply defeat an enemy: it divides bodies from shadows, imprisons the hostile faction in a mirror, erases collective memory, and leaves Y/N vulnerable to a conflict whose history was deliberately hidden.

Origins and Hidden Threat

J-Hope explains that the green-eyed beings come from a sort of other world near the vampires’ own world. Although they resemble the vampires, they cannot pass through the gate separating the worlds. Instead, they sometimes take over vampires’ bodies while those vampires sleep. The green eyes therefore function as a visible sign of an invisible invasion: the familiar body may remain present, while the will controlling it has changed.

The threat is not limited to individual attacks. The green-eyed faction possesses powers, including hypnosis, and its members can use ordinary bodies as entrances into the castle’s community. This makes identity itself unstable. A vampire who appears to be an ally may be controlled by an outside entity, while a shadow with green eyes may reveal the danger more clearly than the borrowed body ever could.

The Castle Crisis

Jin’s later account places the sealing conflict inside the history of the castle. The green-eyed vampires wanted to leave and hunt, but the other vampires stopped them. The faction initially agreed to remain inside, yet the apparent compliance concealed a larger disappearance: the other inhabitants of the house vanished one by one until only the central group remained in the castle.

The crisis becomes visible when the lights suddenly come on and the person standing before Y/N is revealed as nothing more than a shadow with green eyes. The shadow screams and runs away, but the danger immediately expands. Three bodies move, rise, and open green eyes, showing that possession is not an isolated anomaly. The enemy can occupy multiple bodies and turn the castle’s own inhabitants into instruments of the invasion.

The Sacrifice and the Mirror Seal

Jin says that he sacrificed his power to lock the seven green-eyed vampires inside a mirror. The sealing act is therefore both defensive and costly: containment is purchased through the loss of the very power needed to maintain ordinary protection. The remaining vampires are badly wounded, and Jin uses the last power available to him to make them forget that the other people ever existed.

The memory erasure transforms a historical catastrophe into an absent history. The castle’s survivors are not merely unable to explain what happened; they have been made unable to remember that there was anyone else to explain. This produces a fragile peace built on ignorance. The seal preserves the survivors while also preventing them from recognizing the pattern when the green-eyed threat returns.

The mirror is consequently more than a prison. It is a boundary between worlds, a concealed archive of the conflict, and an active route through which the faction can still affect the living. When Jin’s body drops and a shadow remains standing while holding Y/N’s wrist, the shadow pulls Y/N inside the mirror, whose surface feels like water. The original containment structure thus becomes an abduction mechanism, demonstrating that the seal has not erased the enemy’s agency.

Recurrence and Consequences

The conflict repeatedly converts protection into danger. Jin pushes Y/N inside a mirror to keep Y/N safe just before a giant stone is thrown against it and breaks it into pieces. The action saves Y/N from the immediate attack, but the destruction of the mirror also shows how precarious the boundary has become. The elder vampires must use the same portal system that exposes Y/N to the green-eyed faction.

The struggle also explains why appearances cannot be trusted. Jin distinguishes the green-eyed vampires from the others by their eyes, while J-Hope describes their ability to occupy bodies. A stolen body can therefore imitate an ally, and a shadow can be mistaken for a person until light reveals what is actually present. V’s seizure of the book from Y/N adds another instance of uncertainty around identity and possession, though the available evidence does not establish that V is possessed in that moment.

The danger remains connected to Y/N’s larger ordeal. Y/N is abandoned by a mother who drives away, later finds that mother lying in a pool of blood, and is drawn into the vampires’ concealed history. The green-eyed conflict turns that personal vulnerability into a supernatural one: Y/N is treated as a target, pulled through mirrors, and exposed to powers that depend on controlling bodies and knowledge. Even after Y/N confronts Gehan, takes the glass ball, pushes him away, and imagines the gates of Gehenna opening, the larger pattern remains one of contested boundaries, forced transformation, and resistance to domination.

Narrative Significance

The sealing conflict supplies the book’s central grammar of pursuit, concealment, and rescue. The green-eyed faction pursues access to bodies and worlds; the elder vampires respond with prohibition, sacrifice, and memory control; Y/N repeatedly becomes the person through whom the sealed past breaks back into the present. What begins as a defensive victory is therefore also a deferred crisis.

Its deepest consequence is that safety in the castle depends on forgetting. Jin protects the wounded survivors by erasing the existence of the seven enemies, but that protection removes the community’s ability to recognize the signs of renewed invasion. The mirror preserves the hostile faction while concealing it, and the broken mirror turns a prison into a passage. The conflict’s significance lies in this reversal: the elder vampires win enough control to survive, yet the methods of survival—sacrifice, silence, and sealed thresholds—ensure that the original danger can return through the very structures built to contain it.
