Japanese Terrorist: What? I'll fight Hellstar!

The monster let out a series of sharp roars, its massive body twisting towards Amamiya Rin, trying to crush him with its weight.

Amamiya Rin had anticipated this move. He kicked the monster’s massive body, feeling the slimy, resilient texture through the sole of his shoe.

Using the recoil force, Amamiya Rin was thrown backward into the air, where he smoothly tumbled and finally landed steadily.

Just as she landed, the monster twisted its body and chased after her. Amamiya Rin's feet remained motionless, the tip of her knife pointing towards the ground, and her gaze, which could be described as serene, enveloped the monster's entire body.

Three meters, two meters, one meter, half a meter... Just as the two sides were about to collide head-on, Amamiya Rin finally made her move.

He slightly turned his body, thrusting out his wooden sword. With a crisp cracking sound, he vanished from the monster's sight in the blink of an eye, as if he had become invisible.

From an observer's perspective, it was a magical, silky movement, attacking weak points, creating blind spots, escaping through escape routes, and using the monster's own bulky and complex body to deceive itself.

Taking advantage of the monster's inability to change its attack in time, Amamiya Rin swung his sword again, breaking the elbow joint of one of its arms.

Rain Palace Rain fought and retreated.

His steps became more agile as he circled the monster.

The monster's attacks were fierce and direct, but Amamiya Rin always managed to sidestep, slide, and duck at the last second, constantly changing positions and narrowly avoiding attack after attack.

He was much more at ease than in the initial battle.

With only one enemy remaining, tactics can be adjusted accordingly. There's no need to worry about attacks from different directions, and the space for movement becomes more spacious.

By focusing intently on the target within a simplified area, even injuries can be avoided.

Amamiya Rin anticipated the monster's movements, sometimes thrusting straight down, sometimes slashing horizontally.

Each strike precisely hit the monster's joints or Tomie's face, leaving wounds of varying depths.

The dark red blood quickly soaked the floor, and a strong smell of rust filled the air.

Gradually, the monster's movements slowed down.

Its physical strength or energy is limited, and it cannot sustain a frenzied attack for a long time.

Amamiya Rin knew that the time had come.

He dodged another slow attack, his eyes suddenly sharpening.

Breathing has changed.

It is no longer the smooth and long mode of the basic mode, but an extremely deep and slow one, as if trying to take in all the surrounding air into the lungs.

His mind was highly focused, his consciousness sinking into the realm of slaying honed by countless killings and meditations.

When both mind and breath cease, one enters into meditative absorption.

"Unparalleled swordsmanship, sword and Zen as one!"

The transition from stillness to movement is just a thought away.

Amamiya Rin's sympathetic nervous system was actively stimulated to its limit, and adrenaline surged into her blood vessels like a volcanic eruption, with far more power surging and roaring within her body.

Without giving them any chance to react, there was only an extremely fast thrust!

His body leaped into the air, delivering a blade that shot forward like an arrow.

An indistinct brown trail, following the only gap observed in the simplified field, pierced straight into the monster's temple until the blade's guard pressed against its skin.

The powerful impact knocked the monster's body to the ground. Amamiya Rin's feet slammed heavily onto its neck, his wrists twisting as the blade churned inside its skull, mercilessly destroying the monster's brain.

Dark red blood mixed with grayish-white brain matter spurted from the wound, splashing onto Amamiya Rin's cold face.

"Please become a Buddha. The world of the dead is probably not as cruel as the world of the living."

Slowly pulling out the wooden sword, and gazing at the two enormous, deformed bodies, Amamiya Rin prayed sincerely for the two victims.

Before humanity attempts to develop the energy of the underworld, the world of the dead must be the only place of peace compared to the world of the living, right?

The intense flames illuminated the dark room. Amamiya Rin threw away the lighter, turned around, and walked out, shutting out the smoke and flames inside the door.

In the next room, Amamiya Rin found a black notebook containing Takagi's research on Tomie.

Gamma rays can enhance Tomie's regenerative abilities. It has been observed that Tomie's cells can absorb any form of energy, including gamma ray energy...

Strong acids can effectively inhibit Tomie's regenerative abilities... Is Tomie's regenerative ability resistant to strong acids because she is constantly regenerating? Or does she counteract them with even stronger regeneration? Or did she evolve resistance in an extremely short time...?

I always feel like there's a giant hand controlling all of this. The process has been too smooth. Ever since I escaped from the sanatorium and found Tomie, everything has gone smoothly except for researching Tomie...

[Where does the energy for regeneration come from? Even without any energy input, Tomie's body can regenerate, but it will be slow—creating something from nothing?]

[Can Tomie control her regeneration speed? Sometimes she can grow a complete body in a day, sometimes it only takes a few minutes. Can she freely adjust her regeneration efficiency? Could it be that she can store energy and use it to grow when needed?]

Alchemy? Immortality? Do such things really exist? Oh! Tomie can live forever!

[What kind of immortality is it if you can only shed skin? It's ridiculous!]

[When Tomie is mentally unstable, her body splits apart, with another Tomie appearing from her head. Is this due to brainwaves? I don't quite understand.]

[If Tomie wanted to, could she control her splitting? Not just her head, but also the way her arms would grow back after being cut off... It seems impossible. The split Tomies always start from the head; they all think the other is an imposter and can't control it...]

……

Takagi's research on Kawakami Tomie revealed that the information was basically known to Amamiya Rin.

However, some of his ideas inspired Amamiya Rin.

When she is mentally unstable, Tomie Kawakami's body splits into two parts. Is it possible to control this splitting?

And alchemy? Immortality? Shedding skin?

"Is this talking about a flesh-colored monster? The story doesn't seem to fit... well, not exactly. So Takagi's human skin mask is a product of alchemy?"

Amamiya Rin remembers what alchemy was mentioned in the diary.

Junji Ito's manga, flesh-colored monster.

The villain's deceased husband was an alchemist who researched the elixir of immortality. However, he accidentally obtained a byproduct that allowed him to separate his skin from his flesh while still remaining alive. Obsessed with the allure of flesh, the villain not only peeled off his own skin but also tried to peel off his son's skin as well, only to be thwarted by his sister's intervention.

"Completely meaningless, an alternative form of immortality, it can only be used as a human skin mask."

Amamiya Rin shook her head slightly. If you take good care of the shed skin, you can indeed achieve an ageless appearance, but what's the use? The internal organs will still age.
