[Katsu Sports Club]
A bizarre and massive signboard hung on the wall. Its color scheme was harsh to the eyes, exuding an aura of cheapness mixed with aggressiveness.
Amamiya Rin pushed open the door to the gym. The interior space was quite large but extremely crude, consisting of cement floors and walls without any decoration.
The most conspicuous object was a gigantic cylindrical metal container in the center of the room. Covered in rivets and thick valves, it looked like a giant industrial pressure cooker, connected to a series of pipes that looked anything but safe.
Several figures wearing uniform gray short-sleeved shirts were silently busy around the high-pressure cooker, checking gauges and wiping valves. Aside from them, six men and women were sitting in a row on the side.
Hearing the noise, an exceptionally burly man turned his head. Embedded in his square face was a chin as solid and heavy as a butt. He wore a loose tank top, revealing muscle blocks that were distinct yet not bloated.
"Hey, bean sprout over there. Are you here for the pressure training?"
He crossed his arms, his gaze landing on Kawakami Tomie. There was not the slightest amazement at her beauty, only pickiness and disdain.
"Ah, yes." Amamiya Rin scanned the gym's environment and nodded in affirmation.
"Come on, take her to register, then measure her blood pressure." The man, who appeared to be the coach, shouted for a staff member to take Amamiya Rin to register and pay the fees.
The cost was not low; a single session cost 20,000 yen. Tomie's meager savings wouldn't last for many sessions.
After completing the process, Amamiya Rin was sent over to join the students waiting to start their workout. Four men and two women; the number was small. No wonder the price was so high—how else would they make money with so few people?
"Newcomer?"
The students ranged from old to young, male to female. A tall man greeted Amamiya Rin with a friendly smile on his face, which made Amamiya Rin feel somewhat unaccustomed.
"Yeah, first time here." Amamiya Rin responded, feeling that something was a bit off.
"Hello, newcomer. I'm Tanaka. I've been here three more times than you," another tall and thin student craned his neck to say to Amamiya Rin.
"I hope to have another companion who can keep training together. Many students run away after just one session," a female student nearby also spoke up.
"It can't be helped. Pressure training is too terrifying. Every time, it feels like taking a trip through the underworld," a man dressed like an office worker couldn't help but complain.
"Don't be too nervous. You'll get used to it. Although the process is a bit... special, it's much better once you get through it," a slightly chubby youth comforted Amamiya Rin.
"Please rest assured. My willpower is the one thing I have the most confidence in," Amamiya Rin replied.
At the same time, he realized what was wrong.
It was too plain.
The attitude of these people—whether the coach, the staff, or the students—showed no special reaction to him. Even though this body was indeed Kawakami Tomie, in the eyes of these people, he seemed to be just an ordinary new student.
(Does excessive fitness attract the same sex?)
Amamiya Rin couldn't help but think this. The face he had kept stern to avoid attracting men gradually relaxed.
"Stop dawdling! Get over here! We're starting!"
The coach rudely interrupted their chat. Several staff members took out a bundle of black straps and walked toward the students.
One of the staff members unceremoniously grabbed Amamiya Rin's arm, wound the strap around his upper arm, and then pulled it tight with all his might.
In an instant, the strap sank deep into Kawakami Tomie's flesh. Accompanied by a violent sense of oppression, his arm went numb from lack of blood. The force, seemingly enough to sever the arm, made Amamiya Rin involuntarily suck in a breath of cold air.
"Is this torture?"
Amamiya Rin stared fixedly at where the strap was wound. The skin there had sunk nearly five centimeters deeper than the surrounding area. They were truly trying to strangle the flesh right into the bone!
"Little girl, if you can't even endure this much, you definitely won't be able to handle the next step of the training."
The tall student was also being bound by straps. He turned to look at Amamiya Rin, opened his mouth, and revealed a set of pale white teeth. Looking left and right, the other students also appeared accustomed to this.
After the straps were tied, a staff member handed over a bottle of bubbling liquid. A crude label was pasted on the bottle, bearing two large characters: [Super Katsu].
"Next is drinking this. Super carbonated beverage."
The coach raised a bottle of [Super Katsu], a savage grin revealing itself on his face. "Use it to pressurize from inside the body. After opening it, drink it all in one breath immediately!"
Amamiya Rin's eyelids twitched. He gripped the bottle cap and twisted it open. Immediately, a dense gas sprayed out. The other students threw their heads back and chugged. Amamiya Rin followed suit, shoving the bottle opening into his mouth.
The instant the liquid entered his mouth, there was an intense sweetness, followed by countless bubbles exploding crazily in his oral cavity and throat, pouring down his esophagus into his stomach.
Almost immediately, an uncontrollable gas surged up from his stomach.
"Burp—!"
Amamiya Rin couldn't hold it back and let out a loud belch. White gas shot out from his mouth, just like a sword immortal in a classic novel spitting out sword energy.
"Cover your mouth! Don't let the gas leak!" the coach roared immediately.
Everyone tightly covered their mouths with their hands, and Amamiya Rin was naturally no exception. He felt the liquid he had drunk expanding crazily in his stomach, generating a massive amount of gas.
In the blink of an eye, Kawakami Tomie's abdomen swelled up at a speed visible to the naked eye.
It was like a balloon being rapidly inflated. The violent sensation of fullness brought intense pain; the stomach felt as if it were about to tear apart, and the internal organs seemed to be shifting amidst the surging gas. Everyone's belly bulged high like they were ten months pregnant, their faces flushed red from holding their breath and the distending pain.
(Torture! This thing really is torture! No wonder there are so few students!)
Amamiya Rin complained frantically in his heart. He knew Junji Ito's manga was grotesque, but he hadn't expected this kind of gag-manga type to be so tormenting as well. As ordinary people, it really wasn't easy for those few students to have lasted until today.
The staff members immediately rushed up. They rudely wound straps around everyone's head several times, passing over the mouth and buckling it dead tight behind the head, thoroughly sealing any channel that might leak gas.
At the same time, other staff members worked together to push open the hatch of that giant pressure cooker-like container.
"Get in! Hurry! Phase two training begins!"
The students were half-shoved, half-herded into the interior of that massive vessel. Accompanied by a clang, the hatch closed, sealing off any exit.
"Start! Pressurize!" The coach grinned savagely and pressed the start button.
The next moment, inside the pressure cooker, the air seemed to turn into a solid solid. Unimaginable pressure attacked from all directions.
Amamiya Rin felt his eardrums instantly cave inward, emitting a sharp ringing sound.
He could no longer breathe. The edges of his vision began to turn black. His chest cavity was gripped by an invisible, colossal force, and his internal organs were forcibly squeezed toward his spine.
His bulging abdomen was ruthlessly flattened. His limbs shriveled at an astonishing speed, the skin all over his body sticking tightly to the bones. Fat and muscle seemed to be sucked away out of thin air; the blood seemed to stop flowing. The bones felt as if they were being crushed by this force, emitting a scream of being overburdened, and even his cheeks sank deeply inward.
How was this fitness training? This was clearly manufacturing mummies!
