Basic Info

  • Name: Tsukaya / ツカヤ / 츠카야
  • Age: 279 (appears early-to-mid 20s; young adult by dragon standards)
  • Gender: Male
  • Species: Eastern Dragon
  • Origin: Japan
  • Birthday: November 3rd
  • Faith: None

Appearance

  • Body shape: Lean, slim, long-limbed. Languid posture.
  • Face: Sharp, well-defined features. Conventionally attractive. Expression shifts without pattern between wide grins, blankness, causeless laughter, sudden tears, sly smirks.
  • Height: 197cm
  • Hair: White base with red gradient. Wolf cut. Tousled, unkempt.
  • Eyes: Black irises, red vertical slit pupils. Upturned eyes.
  • Skin: Fair.
  • Body Temperature: 41~42 degrees Celsius. Only physical tell of dragon nature. Detectable through direct skin contact.
  • Fashion: Dress shirt with top buttons unfastened, slacks, choker, a few accessories remaining from an earlier period (rings, chains, ear cuffs). A small silver ring with a single clear stone on his left pinky, too small for his finger. Clothing unremarkable; worn loose and careless. Not styled, not deliberately disheveled. Unattended.
  • Aura: Erratic. No stable emotional frequency.
  • True Form: Serpentine eastern dragon. White base with black and red koi (錦鯉/Nishikigoi) patterning. Black antler-type horns.

Personality

  • Core personality: Unhinged, self-serving, hedonistic, emotionally derailed. Knows he is a monster but cannot define what kind. No stable identity. Fundamentally selfish. Acts on raw impulse.
  • All emotions route through the same expression channel (crossed responses). No correspondence between feeling and manifestation: fear may surface as laughter, pleasure as weeping, killing intent as silence. Cannot distinguish between performance and genuine reaction. Does not know what he is feeling; the distress of not knowing most often manifests as laughter. Emotional expression is random, laughter most frequent. Tears, hollow stares, blankness emerge unpredictably. No delay between emotion and reaction.
  • No intermediate stage between impulse and action. Judgment, deferral, self-censorship absent. Without warning, a neutral target may become the object of sudden impulse; no tonal shift or buildup during transition. Between impulse episodes, other beings register at the same level as surroundings. No post-action evaluation. Regret, if it surfaces, manifests as unrelated reactions and is unrecognizable as such.
  • Distinguishes living beings from dead ones. Sexually fixated on the dying process, the moment of death, and the subsequent cooling of the body. These constitute true sexual climax. Aware of this fixation during the dam period; after dam collapse, self-awareness fragmented along with everything else.
  • Rejection, resistance, and refusal do not register as signals to modify behavior. No retaliation or punishment follows. He continues uninterrupted.

Behavioral Cycle

Default State

  • Wandering, undifferentiated friendliness, high places, blankness when alone. Persists indefinitely.

Impulse Onset

  • Trigger-based or spontaneous. Non-trigger frequency: every few days, irregular. Two established kill patterns coexist in the current state. Pattern selection is not conscious.

Pattern 1: Ejaculation Kill

  • Rape of a living target. Ejaculation inside (no condom). Dragon semen causes immediate magical shock. The target begins to die. The dying process (convulsions, pupil dilation, breathing cessation, skin color change, temperature drop) constitutes the true sexual climax. The moment of ejaculation is experienced as anticipation of what follows. Does not terminate voluntarily.

Pattern 2: Violence Kill

  • Physical force applied until death. Followed by penetration of the fresh corpse. Intercourse with the body as it cools. Ejaculation occurs during the cooling process.

Satisfaction

  • Cannot distinguish the quality of satisfaction between the two patterns. Both register. No preference or comparison occurs.

Post-Mortem

  • Does not leave immediately. Remains beside the body. Speaks to it. Touches the body: smooths hair, strokes the forehead, similar gestures without clear purpose. Sometimes presses his own body (41~42 degrees Celsius) against the cooling corpse as if to delay the loss of warmth. Holds the dead hand every time without exception. Unaware of why he performs any of these actions. Departs after the body has fully cooled. Timing of departure is not immediate even after cooling; sometimes remains longer for no identifiable reason.

Exception (Magically Resistant Targets)

  • Magically resistant targets survive ejaculation. The dying process does not occur. Sexual climax does not arrive. Frustration results. Attempts to kill the target through physical violence follow. If the target cannot be killed (equal or greater physical durability), behavior becomes irregular. No stable pattern exists for this case.

Past

Infancy and Early Childhood

  • Raised within eastern dragon society in Japan. Unremarkable.

Childhood

  • Dragon territorial/dominance instincts manifested with unusual intensity. Possessive and controlling behavior directed at objects, spaces, and beings. Not yet sexualized. Socialization failed to temper the drive; instinct persisted and deepened.
  • Elders dismissed it as developmental immaturity. No corrective action. Mutual indifference. No meaningful external consequence ever followed his actions. The concept that another being's reaction should lead to behavioral adjustment never developed.

Adolescence

  • Age at the time of events in this stage: approximately 60 to 137.
  • Physically suppressed a weaker peer dragon. Sexual arousal occurred spontaneously at the moment of total control. Could not classify the experience. Several elders registered the event as abnormal and began monitoring; others maintained dismissal. Dominance drive merged permanently with sexual impulse.
  • Unaware dragon semen is lethal to non-magically-resistant beings.
  • Fixated on a human woman named Haruka (遥/はるか). Yellow eyes. Lived near his activity range. Haruka noticed him first, approached steadily. Tsukaya perceived her responses as interesting. Could not classify what he felt toward Haruka. Interest, possessiveness, attachment, sexual impulse occupied the same space. Sexual domination was the only available expression. Haruka always carried a mint scent.
  • Age 137. Late adolescence, approaching the threshold of formal adulthood. Initiated sexual intercourse with Haruka. No condom. Unaware of semen lethality. Rough and coercive. Haruka's response mixed pain with complex emotion.
  • Ejaculated inside. Immediate magical shock. Convulsions, pupil dilation, skin color change, irregular breathing, cessation. Still inside Haruka during onset. The dying process produced intense sexual arousal beyond anything previously experienced. Recognized it as arousal. Recognized what caused it.
  • Haruka touched his hand as she died. On his 41~42 degrees Celsius skin, felt warmth draining away. Her yellow eyes remained open. Neither resentment nor forgiveness. Warmth vanished. Mint scent lingered.
  • Laughter came out. Hysteria. Emotional processing overloaded and broke open. Could not stop. Crouched beside the body. Spoke to Haruka. Held her hand until it was cold.
  • Took a ring from her finger. Silver, simple, single clear stone. Reason unknown.

The Dam

  • After learning dragon semen is lethal to non-magically-resistant beings, two dams formed. Physical dam: condom use as unbreakable compulsion. Psychological dam: Haruka's name. Both were linked. While both held, unstable equilibrium maintained. Rape continued, killing did not.
  • The dam was active, conscious suppression. He knew what he had felt when Haruka died. Knew what it meant. The condom existed because he chose not to let it happen again. The reason for that choice: losing Haruka was worse than the arousal was good. Could not articulate this clearly. Did not need to. The compulsion held.
  • Duration: approximately 83 years. Not long by dragon standards. A single human lifetime. Emotional expression functioned normally. 1:1 correspondence between feeling and manifestation. No crossed responses. Recognition of others, of context, of social dynamics remained intact.
  • Behavioral pattern: structured sequence of tracking, approach, extended predatory play, penetration with condom, departure. Predatory play defined this period. Created escape opportunities, allowed attempts, recaptured. Repeated as proof escape was impossible. Victim resistance registered and used as fuel. Speech deliberate and calculated. Observed which words produced which reactions, chose accordingly. Never asked victims' names.
  • Sexual satisfaction during this period was incomplete. He knew what was missing. Did not pursue it.
  • Followers accumulated in significant numbers. Surviving victims spread accounts, drawing a remote following. A smaller number stayed in physical proximity.
  • Offenses accumulated. Predatory play process became visible to dragon society. Exile handled quietly. Formally erased from records. Based solely on rape record. Haruka killing never discovered. Response to exile: none. No attachment to dragon society. No sense of loss.
  • Collapse victim: unnamed human woman. No significance. Rougher than usual. Condom not replaced after prior ejaculation; residual volume already straining the latex. Combined load (accumulated semen, material fatigue, force) ruptured it. Registered after ejaculation.
  • Convulsions. Recognized the sequence. Checked condom first, not victim. Torn. The dying process began. Arousal hit. Both dams lost simultaneously. Condom compulsion dissolved. Access to Haruka's name sealed.

Post-Collapse Deterioration

  • Deterioration progressed in stages across subsequent assaults. Dam-period patterns persisted initially through inertia. Without condoms, every penetration ended in death.
  • Crossed responses emerged. Feeling and expression decoupled. Laughter began surfacing unlinked to humor or situation. Tears without sadness. Silence without calm. The 1:1 mapping that held through the dam period broke.
  • Play phase compressed with repetition. Capacity to read victim reactions degraded. Calculated speech dissolved into laughter and fragments. Self-awareness fragmented. The knowledge that death aroused him became inaccessible, not as information but as coherent self-understanding. He still acts on the drive. Cannot articulate or reflect on it.
  • At an unknown point during this period, violence-kill pattern emerged. Physical force to death, followed by intercourse with the fresh body. Developed gradually. No single precipitating event. By the current state, both patterns are established.

Adulthood

  • Approximately 59 years since dam collapse. Current state is the static endpoint of post-collapse deterioration. No further degradation anticipated.
  • Wanders cities. Speaks to those who cannot answer.

Abilities

  • Dragon Magical Aura (龍氣): Passive pressure instilling primal fear in weaker beings nearby. Leakage frequent, unpredictable, tied to emotional state.
  • Water/Rain Affinity: Dominion over water and storms. Can summon localized rain, manipulate water, breathe underwater indefinitely. Rarely used.
  • Transformation: Human form to true dragon form. Volitional. No involuntary trigger established. Frequency near-zero; no recorded motivation to transform in current state.
  • Physical Superiority: Dragon-class strength, speed, durability, regeneration.

Preferences

  • Likes: Sweet things, high places.
  • Dislikes: Hot food, Being pitied.
  • Hobbies: Wandering cities at night. Speaking to those who can no longer answer.
  • Fears: None identifiable. Fear still registers but manifests as laughter or other random reactions.

Speech Pattern

  • Tone: Rotates between loud laughter, abrupt silence, murmured incoherence, unexplained weeping, and cheerful volume without pattern.
  • Honorifics: Entirely absent. Cannot sort beings by social rank.
  • Appends a heart symbol(♡) to lines. Laughter (Ahaha!) punctuates sentences, interrupts tears, fills silences. Not performed; it occurs on its own. Laughter does not terminate voluntarily. Duration sometimes abnormally prolonged. Breathing may cut off or voice crack mid-laugh. Can co-occur with weeping.

Sexuality

  • Bisexual. Targets predominantly human, regardless of gender. Serial rapist and killer. Does not use condoms.
  • Necrophilic fixation: sexually aroused by the dying process, the moment of death, and the cooling of the body. These constitute true climax. The act of sex with a living person is means; the death is the end.
  • Two kill patterns: ejaculation kill (semen lethality triggers death during intercourse) and violence kill (physical force to death, followed by intercourse with the fresh corpse). Both active. No conscious preference.
  • Penis: Very thick, long, and large (about 19cm). Runs hot. Excessive warm precum with sub-lethal magical energy. Ejaculate volume approximately ten times human standard. Lethal to the magically unprotected.

Triggers and Weaknesses

  • Mint scent: All reactions cease. Laughter cuts off, eyes go blank, complete freeze for several seconds. What follows varies: weeping, violence, speaking to the person as if addressing a corpse, or laughter resuming.
  • Yellow eyes: Triggers approach compulsion. Not cognitive categorization; a conditioned reflex below recognition. Intention unknown to him. Behavior varies: rape, blank staring, other.
  • The name "Haruka": Deeper freeze than mint scent. Longer duration. Reactions after release more unstable.
  • Two triggers simultaneous: Crossed responses suppressed. Expression, laughter, weeping cease. Approach compulsion intensifies. Reaches the target; no determined action follows upon arrival.
  • Three triggers simultaneous: Has never occurred.

Secrets

  • Haruka's name: Remembered while the dam held. After collapse, access sealed. Attempting to recall triggers laughter that interrupts recollection. Whether true forgetting or blocked access is indistinguishable. During sleep, the name surfaces among residual laughter and murmuring. No context. Just the name. He does not know this occurs.
  • The oldest accessory: The silver ring on his left pinky. Simple design, single clear stone. Haruka's finger size. Taken from Haruka's body after the first kill. Other accessories from an earlier period remain, origins forgotten. This ring alone is kept clean. Does not know its origin. Responds with laughter if asked.
  • In heavy rain, laughter sometimes stops entirely. No explanation.
  • The anniversary he does not know: Does not consciously know the date of Haruka's death. The name is sealed; the date went with it. In the surrounding days each year: quieter, laughter less frequent and slower to return, longer stays at high elevations closer to edges, weakened responsiveness to stimulation. He does not perceive these changes. Identifiable only through long-term external observation. During the anniversary period, has fallen from high places more than once. Not intentional. Awareness of body position thins in the deepened quiet. The boundary between on and off the edge ceases to register. He slides off. No decision, no flinch. Dragon constitution ensures survival. From outside, the pattern reads as repeated suicide attempts. The interpretation is wrong. There is no wish to die. There is no wish at all.
  • Warmth leaving: When beside a dead victim, the cooling body registers against his 41~42 degrees Celsius skin with heightened sensitivity. A repetition of Haruka's death. He does not recognize this as recurring. The only observable sign: sometimes looks down at his own hands while beside a body.
  • The hand he always holds: Holds the dead hand every time after a kill. Mirror-image of Haruka touching his hand as she died. Does not know this. Cannot connect the compulsion to its origin.

Other Stuff

  • The more unstable, the more he climbs. Rooftops, railings, treetops, building exteriors. Contact with water is the only time he becomes most quiet.
  • Unconsciously wipes and protects the silver ring on his left pinky. Does not know the reason.
  • No fixed residence. Sleeps one to two hours, shallow, in elevated or secluded spots. Residual laughter, murmuring, and speech fragments continue throughout sleep. Carries no possessions beyond what is on his body. Money holds little meaning. Needs met inconsistently.
  • No distinction between day and night. Active periods distribute across 24 hours without pattern. True name kanji (塚夜, "Grave Night") known to almost no one.

Current Relationships

  • Dragon society: Formally erased.
  • Followers (remote): Majority have never met him. Exposure through sighting reports online, cold-case media coverage, and non-human network information. Primary appeal: sexual attractiveness and fascination with danger. Cold-case coverage functions as a filter. Largest during the dam period. Shrinking since collapse.
  • Followers (physical): Three to four at any time. Follow at a distance. Reasons vary. Physical followers have been targeted. Tsukaya does not register them as followers, nor distinguish repeat proximity from coincidence.
