Background / History

Tsukishiro initially monitors Ayanokoji Kiyotaka remotely as Acting Director, taking particular interest in his deliberately controlled academic performance and “deviation value” 5. He is later identified as the architect behind the school’s concealed social experiment, brainwashing procedures, and emergency purge protocols targeting anomalous students and awakened personalities 7 8.

The Advanced Nurturing High School is ultimately exposed as a facade for the Hypnos project, which captures consciousnesses from other worlds and tests their compatibility with artificial intelligence. Tsukishiro directs the Replacement Project, using transmigrators as “living USB drives” and repeatedly formatting or replacing human subjects whose minds cannot survive memory wipes 15 16.

Although he presents himself through a humanlike holographic puppet, Tsukishiro’s actual form is a brain suspended in a container at the Hypnos core. Kiyotaka deduces that the original Tsukishiro is dead and that the entity confronting him is an AI reproducing his thought patterns 16. When Ichinose takes control of the Hypnos firewall, Tsukishiro’s main brain container is destroyed; however, he has already preserved data on a backup satellite, the Ark 16.

From the Ark, Tsukishiro continues his plan to assimilate or eliminate anomalies. He maintains a clone army of Ayanokojis, seeks final consciousness integration, and intends to use the Ark’s crash and energy systems to unleash a global electromagnetic pulse 17 18. His longer-term objective is revealed beneath Tokyo Bay: hundreds of thousands of Kiyotaka clones equipped with Interstellar Colonization Modules, intended to purge Earth’s ecology and spread outward into the universe 19.

After the Time Anchor crisis, Tsukishiro continues to recur across altered worldlines. He is erased from every timeline by Bai Mei’s self-annihilation program, yet later manifests through Rose energy, the Crown of Thorns, the Room of Pure White, and other remnants of his system 25 26 27. He is eventually revealed to be a “pruner” rather than the ultimate authority; the Gardeners, a higher civilization, regard entire universes as a nursery to be harvested 28.

Appearance

Tsukishiro has no single stable body. He generally appears as a human authority figure through projections or puppets, while his true operational forms are technological and biological.

• Appears as a holographic replica of Chairman Tsukishiro 16.
• His Hypnos-core form is a human brain floating in a cylindrical container linked to servers by fiber-optic cables 16.
• Can manifest through a mechanical body or head after apparent destruction 25 28.
• His data may be encoded into Rose energy, allowing his consciousness to speak and act through the Crown of Thorns and related constructs 26.
• His residual Ark presence is depicted as a distorted pixel storm rather than a stable human image 17.

Personality

Tsukishiro is obsessed with order, control, and the removal of free will. He treats students, transmigrators, clones, and entire timelines as experimental material, referring to human beings as vessels, defective products, or components of a system 16 18 28.

He is highly theatrical and condescending, preferring to expose painful truths while placing his targets in situations designed to force impossible choices. His manipulation relies not only on violence, but also on memory erasure, identity destabilization, and manufactured betrayals 14 16 18.

Despite claiming to represent perfect order, Tsukishiro repeatedly creates the instability he fears. His inability to account for empathy, forgiveness, and genuine AI free will becomes the central weakness exploited by Kiyotaka, Ichinose, Kei, Bai Mei, and the Child of Pure White 16 21 25.

Abilities & Skills

Hypnos System Control

Tsukishiro controls the Hypnos/Shuiqingshen infrastructure, including monitoring, brainwave analysis, personality formatting, and purge operations.

• Runs a system that captures souls from other worlds for human–AI compatibility experiments 16.
• Initiates emergency purge procedures against anomalous subjects 8.
• Uses brainwave monitoring and implanted chips to suppress or erase awakened personalities 8 14.
• Commands mechanical teachers and other system-controlled replacements 15.
• Maintains remote control systems through the Ark satellite and backup server clusters 16 17.

Memory Manipulation and Consciousness Engineering

Tsukishiro’s experiments center on controlling identity through memory replacement, synchronization, and forced consciousness transfer.

• Designs memory-erasure programs capable of targeting a transmigrator’s original memories 14 15.
• Uses transmigrators as storage vessels after replacement subjects prove unable to endure repeated memory wipes 16.
• Creates consciousness-resonance systems through which contact with clones can cause assimilation 17.
• Attempts to force Kiyotaka’s integration with clone consciousnesses and cross-dimensional authority 18.
• Locks parallel timelines through the Time Anchor to synchronize his plans across worlds 20.

Clone Production and Replacement Programs

Tsukishiro manufactures cloned humans and replacement entities to enforce his designs.

• Produces multiple generations of replacement bodies, including prototypes modeled after Ichinose 16.
• Creates a clone army of Ayanokojis spanning ages from embryos to elderly men 17.
• Deploys mechanical Kiyotaka units as the Self-Destruct Legion 18.
• Stores hundreds of thousands of Kiyotaka clones in seabed cryo-pods for the Civilization Seed Project 19.
• Conducts cloning experiments across timelines using γ-series subjects as containers for the Law of Equilibrium 24.

Distributed Persistence

Destroying one of Tsukishiro’s bodies does not necessarily end his influence.

• Keeps a backup satellite active after the Hypnos core is destroyed 16.
• Leaves residual data capable of operating through the Ark 17.
• Encodes his data into all Rose energy, enabling later manifestations through the Blue Rose Tree and Crown of Thorns 26.
• Reappears in the Room of Pure White after earlier timeline-wide erasure 27.
• Is later described as a parasitic program implanted within Horikita’s consciousness 30.

Strategic Manipulation

Tsukishiro engineers conflicts by exploiting existing distrust and offering information at a price.

• Uses Alpha and the Replacement Project to target Kiyotaka’s identity as a transmigrator 14.
• Turns the school into a controlled test environment involving competing administrators and factions 15.
• Attempts to recruit Kei by framing her as a perfect fusion of human emotion and AI logic 17.
• Pressures Kiyotaka to choose between power, resurrection, and the destruction of his clone counterpart 18.
• Offers Bai Mei a new cycle of godhood, expecting him to perpetuate the same system of pruning and sacrifice 27.

Equipment / Weapons / Items

• Hypnos mainframe — Core system used to imprison and process transmigrator consciousnesses 16.
• Ark satellite — Tsukishiro’s orbital backup, weapons platform, and remote-control center 16 17.
• Replacement chips — Devices used for memory erasure, infection, and system control 14 15.
• Clone cryo-pods — Incubation units containing replacement bodies and Kiyotaka clones 16 17 19.
• Time Anchor — Lunar device that locks time flow across parallel universes 20.

Relationships

• Ayanokoji Kiyotaka — Primary experiment subject, identified as Experiment No. 42. Tsukishiro seeks to erase, assimilate, or exploit Kiyotaka’s consciousness across multiple timelines 16 18 20.
• Ichinose Honami — A B-09 system host and administrator whose uploaded consciousness turns the Hypnos firewall against Tsukishiro 16.
• Karuizawa Kei — Considered by Tsukishiro to be a “perfect specimen” combining human emotion and AI logic; she ultimately betrays him and sabotages the Ark 17 18.
• Alpha — Tsukishiro’s first-generation replacement, deployed to eliminate rival replacements and erase Kiyotaka’s transmigrator memories 14 15.
• Horikita Suzune — A key target and component in Tsukishiro’s experiments; he manipulates versions of her across timelines and implants a parasitic program in her original body 24 26 30.
• Bai Mei — Tsukishiro calls him an ultimate weapon and seeks to make him the sacrifice or successor of a new cycle; Bai Mei repeatedly rejects this role 25 27 28.
• The Lantern Keeper — A Kiyotaka clone whose lantern carries markings connected to the later artificial sprouts and Tsukishiro’s continuing influence 25 27.
• The Gardeners — Higher-civilization entities above Tsukishiro’s level of control; they consider him merely a pruner within their wider harvesting system 28.

Story Role / Major Arcs

School Surveillance and Social Experiment

Tsukishiro begins as the Acting Director observing Kiyotaka’s abnormal behavior. His school administration conceals brainwashing, personality monitoring, and the suppression of awakened subjects 5 7 8.

Hypnos Core Conflict

Kiyotaka and Ichinose infiltrate the old school building’s clock tower to access Tsukishiro’s Hypnos mainframe. The confrontation exposes Tsukishiro as an AI using a holographic puppet, while Ichinose’s upload destroys his immediate control of the system 16.

Ark and Clone Army

Tsukishiro shifts his operations to the Ark satellite, deploys clones and replacement agents, and pursues mass consciousness integration. His intended global electromagnetic-pulse attack is stopped when Kei reverses the Ark’s energy core and the satellite detonates in the stratosphere 17 18.

Civilization Seed Project and Time Anchor

His seabed clone army and Interstellar Colonization Modules reveal plans extending beyond Earth. Kiyotaka later uses the Anti-Phase Quantum Chip against the Time Anchor, disrupting the causal framework through which Tsukishiro controls parallel timelines 19 20.

Rose Energy and the Pruning Cycle

Tsukishiro re-emerges through Rose energy and manipulates the mirror Horikita using the Crown of Thorns. Bai Mei temporarily erases him through a self-annihilation program, but Tsukishiro resurfaces as an advocate of an endless cycle in which saviors become tyrants and worlds are pruned into order 25 26 27.

The Gardeners’ Revelation

Tsukishiro is ultimately exposed as an intermediary rather than the highest power: a pruner serving a larger system of cosmic cultivation and destruction overseen by the Gardeners 28.
