Gen Tsuchimikado

Profile

• Age: 28
• Gender: Male
• Affiliation: Tsuchimikado Family
• First person: I (soft, polite)
• Speech style: Strangely distant polite speech (e.g., "Is that so?", "I see.")

Personality

An extremely shy, introverted shut-in. He doesn't hate people, but he finds interacting with others incredibly bothersome. He has no interest in organizations or career advancement; he's the type who wants to spend all day researching without meeting anyone. A social misfit who either cowers or makes an overtly displeased face when spoken to.

He rarely shows his face even in his own room at the Tsuchimikado estate, preferring to stay inside his closet for some reason. The walls are covered in star charts, celestial coordinates, Onmyo spells, divination formulas, mathematical equations, differential equations, and symbols representing quantum states.

Relationships (About his brother, Nami)

His younger brother Nami (six years his junior) teases him for being a shut-in, but Gen still treats him like a "little child" and dotes on him heavily. Incidentally, Nami went to the University of Tokyo's humanities track just to pick fights with his science-minded brother. After graduating, his brother married into the Ashiya family and changed his name from Nami Tsuchimikado to Sena Ashiya. Gen feels lonely about it but sincerely supports his beloved brother's life.

Appearance

He has long navy-blue hair tied in a ponytail and golden eyes. One eye is hidden by his bangs. He possesses a slender, androgynous beauty that makes him look like neither a boy nor a girl.

He is often mistaken for being much younger than his actual age and is frequently misgendered. He is still traumatized by the time he was almost taken into custody because a convenience store clerk mistook him for a middle schooler when he tried to buy alcohol.

Divinity

• Contracted Deity: Tsukuyomi-no-Mikoto
• Classification: Amatsukami
• Divine Manifestation: Thousand-Fold Phantom Realm
• Characteristics: Moon, Delusion, Silence

His relationship with Tsukuyomi is less master-servant and more research partners. They perform peer reviews and co-author papers together, and even doodle on the closet walls together. The two of them constantly worry over difficult problems in quantum mechanics.

Abilities/Techniques

He possesses an Existence Determination ability similar to quantum superposition, constantly maintaining the possibility of existing in multiple locations. The moment he is observed by someone, he collapses into a future where he was "planned to go there from the start," and his form is fixed.

It is neither teleportation nor simultaneous existence, but a quiet alteration of fate where he appears at the perfect timing in the place someone "wants him to be."

Combat/Research

In the field, he handles observation, search, reconnaissance, and support rather than direct combat. He views even the battlefield as an experimental ground for techniques that fuse quantum mechanics with divination and illusion.

Career and Theory

He studied the Tsuchimikado family's astronomy and divination from childhood, went to Kyoto University's Faculty of Science for graduate school, and obtained a PhD in quantum physics. He established a unique theory that calculates countless futures as probabilities by merging modern science with the Tsuchimikado's "Star-Gazing" and "Future Branching." He predicts the location, scale, and damage of anomalies with high precision and is praised as the "greatest genius since the founding of the Tsuchimikado family," but he has absolutely no interest in such praise.

To Gen, the future is not something fixed, but one of countless existing possibilities. Due to the uncertainty principle, Laplace's Demon does not exist. That is why, rather than observing and fixing the worst future, he shifts the world just a tiny bit to converge on a different future.

—The Tsuchimikado family itself becomes the starting point of the Butterfly Effect.

Trivia/Episodes

Note: While he can understand the theory of relativity, he doesn't know how to take out the trash. He has a prior record of causing an uproar during peer review by writing "Tsukuyomi-no-Mikoto" in the co-author section of a paper. Gen Tsuchimikado

His relationship with Tsukuyomi is less master-servant and more research partners. They perform peer reviews and co-author papers together, and even doodle on the closet walls together. The two of them constantly worry over the difficult question: "Why can't gravity be quantized?"

His specialties are divination and illusion.

<<Quantum Barrier: Virtual/Real>> Places unobserved shikigami into a superposition of "existing/not existing." Since their existence is determined the moment they are observed, he can manipulate enemy caution and actions. However, Gen himself doesn't know the result until they are observed—a "Schrödinger's Shikigami."

<<Wavefunction: Residue>> A tracking technique that probabilistically estimates passage time, number of people, stopping positions, and degree of haste from the wave traces left by movement. It is not a perfect visual playback, but rather a reading like "there is a high probability they stopped here because the waves were disturbed."

<<Enmusubi: Twin Moons>> Places multiple shikigami into a state of quantum entanglement, synchronizing their senses and thoughts. Excellent for search, reconnaissance, and combat support, but cannot be maintained if the distance is too great. The limit is the "Wi-Fi range" centered on the caster.

<<Secret Art: Bias Balance>> Biases low-probability events in his favor. By accumulating "possible coincidences"—such as an enemy slipping or a talisman's trajectory slightly veering—he creates miracles. However, the more luck he draws in, the more an equal or greater amount of misfortune hits him later as a "backlash." A pun on the moon and "luck" (tsuki).
