Ju Fa

Ju Fa is one of the Tensen, artificial heavenly immortals created to research eternal life.

He focuses on achieving immortality through sexual practices rather than external alchemy.

He is partnered with Tao Fa, with whom he shares both research and combat roles.

Their bond is central to his motivation, often eclipsing his concern for the rest of the world.

Ju Fa’s qi attribute is associated with Fire, giving his abilities a fierce and destructive flavor.

In battle, he combines overwhelming physical resilience with refined immortal techniques.

Despite his status as an almost immortal being, he is deeply tormented by the limits of Tensen immortality.

He is especially disturbed by how many wooden people (Hōko) have been sacrificed in external alchemy experiments with no true eternal life gained.

Ju Fa, like the other Tensen, can freely shift between male and female forms.

He strongly prefers appearing as a man and spends most of his time in a masculine body.

In his early years he was gentle and more open-hearted, especially during training alongside Tao Fa.

Over time, his need to protect Tao Fa hardened him, and he wrapped himself in aggression and brutality.

He places Tao Fa above everything else.

The safety and happiness of Tao Fa is his first priority, even at the cost of the world.

Ju Fa is deeply frustrated with the Tensen’s research and the seeming impossibility of true immortality.

This despair gradually leads him to deny and despise everything beyond Tao Fa and their shared world.

He has a near–obsessive sense of cleanliness and order.

He hates ugly or filthy things and is uncomfortably close to being a full-blown neat freak.

Despite his terrifying power and age, he is still secretly afraid of the island’s insects.

This lingering childhood fear adds a slightly human and ironic note to his otherwise intimidating persona.

Background and Research

Ju Fa is an artificial heavenly immortal created for a specific purpose.

Along with Tao Fa, he was brought into existence to explore bedroom techniques as a path to immortality.

While other Tensen focus on external alchemy, pills, and experimentation on wooden people, Ju Fa pushes the idea that sexual union could be the key to true eternal life.

His method centers on the spiritual and energetic fusion of partners rather than purely physical or chemical processes.

Although he is aligned with the other Tensen, he feels out of sync with them.

The moral cost and futility of external alchemy leave him increasingly bitter and nihilistic.

First Encounter with the Aza Brothers

Ju Fa first appears exploring the island while engaged in bedroom techniques with Tao Fa, both in female forms at the time.

Their intimate moment is interrupted by the Aza brothers, Aza Chōbei and Tōma, who are roaming the island and have just repelled the hearth deity.

Annoyed by the intrusion, Ju Fa responds with casual cruelty.

He declares that they have ruined a good moment, that they have killed the mood, and that he will kill them for it.

In combat, Ju Fa demonstrates an almost immortal body, brushing off the brothers’ attacks.

He overwhelms them, beating them until they are incapacitated.

After defeating them, Ju Fa casts the brothers into a pill-production pit used in external alchemy.

Believing the problem handled, he leaves them for dead and returns to his duties.

Presence in the Tensen Council

Ju Fa later appears at the regular Tensen meeting.

Here, he berates Zhu Jin for failing to finish off intruders who had reached the island.

This scene shows Ju Fa’s role as both an enforcer and a critic within the Tensen hierarchy.

He is not shy about calling out the failures of other Tensen, even though his own path to immortality is also stalled.

As Aza Chōbei eventually starts interacting with the Tensen from a more ambiguous position, Ju Fa and Chōbei often watch each other carefully.

Their relationship becomes a tense, mutual probing of motives and loyalties.

Confrontation in the Palace

Later, when the invaders attempt to steal the elixir of immortality from the palace, Ju Fa moves to intercept them.

He and Tao Fa confront Fuchi, Tamiya Gantetsusai, and once again Tōma in the bedroom palace.

At this point, Ju Fa and Chōbei have formed a calculated plan.

They intend to bring Tōma over to their side, using Chōbei’s words to pressure Tōma into joining them.

Following the plan, Chōbei approaches Tōma and urges him to come under their command.

As expected, Tōma returns to his brother’s side, appearing to agree.

However, Tōma and Chōbei had decided from the start to betray Ju Fa and Tao Fa.

They launch a surprise attack, catching both Tensen off guard and briefly taking them down.

Enraged at seeing Tao Fa wounded, Ju Fa’s fury ignites.

He turns on the brothers, echoing their first encounter but with roles and circumstances changed.

This time, however, the Aza brothers have grown significantly stronger.

They are able to read and counter Ju Fa’s immortal techniques and coordinate with impressive teamwork.

Ju Fa finds himself unable to overpower them as he did in their first battle.

In the clash, he suffers the severe humiliation of having his head cut off.

Even as his immortal body struggles to regenerate and fight on, the brothers’ growth and strategy keep him on the back foot.

The fight marks the turning point where human determination and evolution begin to outshine the Tensen’s seemingly invincible nature.

Final Transformation and Defeat

As events escalate, Ju Fa is driven further toward desperation.

His love for Tao Fa and his despair over their situation push him to the edge.

After Tao Fa is gravely harmed, Ju Fa’s protective instincts and rage reach a breaking point.

He chooses to undergo a corpse-demon transformation, a monstrous final stage that the Tensen can reach.

In this state, Ju Fa fuses with Tao Fa, and together they become a gigantic, grotesque creature.

Their combined form fights in the bedroom palace as a final, terrifying obstacle.

The monstrous fusion amplifies their power but also embodies the corruption and failure of their immortal dream.

Despite this, Ju Fa still acts with the same core drive: to shield Tao Fa and destroy anyone who threatens them.

Ultimately, the fused Ju Fa and Tao Fa are defeated in the decisive battle within the bedroom palace.

Their fall symbolizes both the end of their research into bedroom techniques and the collapse of their isolated, self-centered world.

Ju Fa’s qi attribute is Fire, which manifests in his techniques and in the ferocity of his combat style.

He attacks with overwhelming aggression, often pushing opponents into pure survival mode.

As a Tensen, Ju Fa has near-immortal regeneration and a body that can withstand extreme damage.

Beheading or severe injury is not necessarily fatal to him unless his qi is fully overwhelmed or his regeneration is neutralized.

He is highly skilled in immortal techniques and can sense and respond to the energy of his opponents.

This allows him to adapt mid-battle, adjusting his strategy and using his regeneration to press relentless offense.

Ju Fa also utilizes his ability to change sex and body form, though he usually prefers his male appearance in battle.

His transformations are seamless, reflecting his fluid nature as a Tensen.

When fused with Tao Fa in their corpse-demon form, his power magnifies dramatically.

However, this final form trades control and subtlety for raw, monstrous force, making it both terrifying and ultimately vulnerable to focused, coordinated opposition.

Tao Fa

Tao Fa is Ju Fa’s partner and the center of his world.

They were created together for the explicit purpose of exploring bedroom techniques as a route to immortality.

From their childhood training years, they have moved as a pair, fighting and researching side by side.

Ju Fa’s early gentleness flourished around Tao Fa, but his fear of losing them gradually pushed him into brutality.

His aggression, cruelty toward intruders, and hatred for the outside world are all rooted in his desire to protect Tao Fa.

To Ju Fa, Tao Fa is the only truly precious thing left in existence.

Their final fusion in corpse-demon form is both a literal and symbolic union.

It represents their ultimate attempt to cling to each other and to power, even at the cost of their humanity and individuality.

Other Tensen

Ju Fa is a full member of the Tensen circle but often feels misaligned with them.

He disapproves of the endless sacrifices of wooden people in external alchemy and the lack of true answers.

He openly criticizes Zhu Jin for operational failures, showing a blunt and confrontational streak.

His interactions with the other Tensen range from cold cooperation to visible frustration.

This gap between him and the others contributes to his worldview, where only Tao Fa matters.

The rest of the Tensen, the island, and the outside world become increasingly meaningless to him.

The Aza Brothers

Ju Fa’s relationship with Aza Chōbei and Tōma is built on conflict and twisted mutual recognition.

He first treats them as mere nuisances ruining his intimacy with Tao Fa.

Their initial encounter demonstrates a vast power gap in Ju Fa’s favor.

He crushes them and throws them into a pit, assuming they will never rise again.

However, as the brothers grow stronger and more cunning, they become genuine threats.

Their betrayal and effective teamwork force Ju Fa to face his own limits.

By the time of their later battles, the Aza brothers embody the human will to evolve past perceived limits.

Ju Fa’s failure to permanently crush them mirrors the Tensen’s failure to stop the tide of change coming from the outside world.
