Puppeteer

Puppeteer works for Haijima Heavy Industries, specifically in its research and development facilities focused on ability users.

Within the company, she is assigned to the Ability Development Laboratory, where children who have just awakened their abilities are studied and trained.

She serves as an educator and caretaker, teaching children how to understand and control their powers.

To ease their fears and create a friendly atmosphere, she often entertains and comforts them by using her controllable dolls, the Dominions.

Although she appears calm and gentle in her interactions, her role is deeply tied to Haijima’s structured and sometimes harsh environment for ability users.

Despite this, her use of the Dominions adds a playful and whimsical element that softens the lab’s otherwise clinical feel.

Her full name is never stated, and no canonical details such as age, birthday, height, or blood type have been disclosed.

She is primarily identified by her codename and her position within Haijima.

Puppeteer is classified as a third-generation ability user who channels her thermal energy into mechanical dolls known as the “Dominions.”

These dolls run on her heat output and can be precisely manipulated through cables, much like classic marionettes.

The Dominions are smaller than children in size, giving them a toy-like appearance at first glance.

However, their strength is surprisingly high: they can catch and throw objects like matchboxes with notable force and even deflect or evade direct attacks from powerful enemies such as Iron Owls.

Each Dominion is connected to Puppeteer via control cables that transmit both mechanical guidance and her thermal energy.

By adjusting the tension and movement of these cables, she can coordinate multiple dolls at once, allowing complex group maneuvers.

The Dominions possess limited flight capabilities, enabling them to move quickly through the air during combat or training scenarios.

This mobility lets them perform surprise attacks, evasive maneuvers, and overhead support, making them far more than simple stage props.

One of their signature techniques is humorously named the “Fart Blaster,” a special move where the Dominion releases a concentrated blast of flame from the area corresponding to its rear.

Despite the comedic name and presentation, the attack is genuinely powerful and can be used offensively in close or mid-range combat.

The term “Dominions” is plural for a reason, as multiple units of the same model exist and can operate together under Puppeteer’s control.

Among these, there are special variants described as “for discipline,” which are built with a stronger combat focus and enhanced performance for restraining or subduing targets.

Because her power is externalized through machines rather than direct body manipulation, Puppeteer’s fighting style is highly tactical and indirect.

She can stay at a distance while her heat-powered dolls engage the enemy, support allies, or manage training exercises with the children in Haijima’s care.

Within Haijima Heavy Industries, Puppeteer is part of the Ability Development Laboratory staff dedicated to nurturing young ability users.

Her official duty is to guide children who do not yet understand how to control their powers, helping them avoid accidents and refine their abilities.

She uses the Dominions not only as tools of combat but also as teaching aids and companions.

Their cute, puppet-like appearance helps nervous children relax, making them more open to instruction and less afraid of their own powers.

In practical terms, she can demonstrate precise thermal control, teamwork tactics, and safe power usage using the dolls as examples.

This approach blends play with training, turning potentially frightening abilities into something more manageable and structured.

While Haijima as an organization often has a cold and utilitarian reputation, Puppeteer represents a softer side of its operations.

Her presence, together with the Dominions, brings a sense of playfulness and warmth into an otherwise strict research facility.

Puppeteer comes across as composed, gentle, and patient, fitting her role as an educator of vulnerable and confused children.

Her willingness to use charming, silly techniques—like the Fart Blaster—shows that she is not afraid to look a bit ridiculous if it helps others relax.

The contrast between her whimsical dolls and their surprisingly high combat power makes her stand out among other ability users.

She embodies a mix of caretaker and hidden powerhouse, quietly supporting Haijima’s operations from behind the scenes.

The Dominions are small mechanical dolls powered directly by Puppeteer’s thermal energy.

They are linked to her by control cables that function both as puppet strings and as conduits for her ability.

Physically, they are built to look like puppets rather than heavy weapons, which makes them non-threatening at first sight.

Inside, however, they are sturdy enough to withstand strong impacts and to generate explosive bursts of flame.

Their key known features include:

Compact size, smaller than an average child

High physical strength relative to their build

Limited flight capability

Flame-based special attacks, notably the Fart Blaster

Multiple identical units for coordinated action

Special “discipline” models optimized for combat and restraint

Because she can field several Dominions at once, Puppeteer effectively fights as a small squad all on her own.

This makes her especially dangerous in enclosed spaces like laboratories or facilities, where her dolls can use terrain and vertical space to their advantage.

Puppeteer is voiced by Saori Hayami in her animated appearances.

Her calm, clear voice performance emphasizes the character’s composed demeanor and gentle approach, while still conveying authority when she commands the Dominions.
