My Refrigerator Turned Into A Dungeon

Chapter 183:

Shark's Training Part

[Bam! Bam!]

"That's it, one-two! Use your legs. Use them more forcefully!"

"Ugh!"

The sound of Shark hitting the sandbag reverberates in the antechamber of the refrigerated dungeon. Because I'm training Shark, who came over after school, at my place.

[Bam! Bam!]

"Come on! Step into it more firmly! Don't hesitate! Step in as if you're going to tackle them!"

Sweating, Shark hits the sandbag in training attire. Wearing a stylish navy and gray top with pants that don't hinder her movement.

As I watch from behind, I adjust my sunglasses.

Yes, in my mind, I always wear sunglasses as a coach. Not to hide my gaze from Shark's impressive high school girl bust or fresh high school girl hips, but to conceal my tendency to glance at them.

[Bam! Bam!]

"Don't rest now! Your pace is dropping! Thirty seconds left!"

A moment alone with a cute high school girl. But there's no hint of sweetness in the air; tension fills the antechamber.

But that's how it should be. Shark's wrists and ankles are wrapped in mucus tubes under the dungeon's pale light, and thick mucus is wound around her waist, connecting to the back wall. Without exerting enough force, she'd topple backward in an instant.

And the sandbag Shark is hitting isn't just a regular sandbag. It's a mucus sandbag with elasticity resembling flesh, hanging from the ceiling in large droplets.

Yes This is the dungeon hole' for Shark, who sought coaching from me to defeat the detestable antagonist.

"All right, two-minute break! Use it to catch your breath properly! Meditative breathing!"

"Haah! Haah! Haah!"

As Shark collapses backward, pulled by the mucus tubes, she tries to regulate her breath, lying on her back.

(Despite being strong-willed, she has a lot of guts)

I've trained Ruu and others with the same training menu when they came over, but none were as committed as Shark. Of course, they're doing it seriously, but not as intensely.

(But maybe it's also because she has a strong dislike for her Aikido classmates.)

It might seem like I'm encouraging fights, but I know Shark isn't the type to engage in malicious bullying. I want to support her. Well, the main reason might be, "Losing is frustrating!"

Aikido is essentially a martial art focused on countering.

Yeah, like counter-attacking to neutralize the enemy's attack by matching their movements.' Wasn't it based on techniques to counter opponents with swords or knives while unarmed? I think it was something like that. I should look it up properly some time.

But Shark is also quite skilled, able to perform martial arts-like moves.

She learned it from the Milliota brothers, but the technique involves grabbing the opponent's wrist or attacking with a punch or knife, throwing them down, and delivering a blow. While this is a move in martial arts, Aikido further immobilizes the opponent by manipulating the wrist, rendering the enemy unable to counter due to the pain.

I know this much. I've watched various videos of martial arts masters to study when training myself.

"All right, it's been two minutes, get up. Before the third set, let's review your movements."

Though Shark is still breathing heavily, she staggers to her feet as I call out to them and approach the sandbag. I demonstrate the movements slowly so Shark can memorize them well.

"Listen up for a review. If you know the opponent is using Aikido, you don't need to worry about punches or kicks."

"Yeah"

"But if we throw a punch, they'll immediately manipulate our wrists and throw us. They specialize in that. So, use elbow strikes."

From a stance with both arms guarding the head, I slowly demonstrate elbow strikes against the sandbag, pushing the shoulders forward with the elbows.

"This way, the opponent can't manipulate our wrists. However, if they grab our arms, they can still manipulate our elbow or shoulder joints. So, it's important to keep the elbows bent and not give them space to insert their hands."

To make it easier to remember, I repeatedly demonstrate the movement of pushing the shoulders forward with the elbows in slow motion. Looking into Shark's eyes, I see them earnestly trying to memorize my movements. Good, she seems to be doing fine.

"And the most important thing is the trembling leg That's essentially an emergency brake. It's a technique where you abruptly stop to transfer all the kinetic energy onto the opponent at the moment of impact. You stop abruptly and transfer all the kinetic energy onto the opponent."

It's easier to understand if you think of it as a traffic accident.

In a race, a car crashes. But despite the car spinning wildly, the driver inside is unharmed. That's because the kinetic energy is dispersed as the car rolls, dissipating away.

To put it another way, the car is taking evasive action.

But if it's a crash into a concrete wall, it's bad news. Even though it might seem more dramatic, abruptly stopping at high-speed transfers all the kinetic energy directly onto the driver.

That has resulted in many drivers losing their lives.

"Transfer all the kinetic energy you've generated onto the opponent"

"That's right. You've learned about constant velocity and the laws of inertia in school? But to put it simply, transfer all the kinetic energy you've generated onto the opponent with an abrupt stop!'"

"What?! I study too, you know! I'm not that dumb!"

"Haha, I see. Did you understand the explanation just now?"

Shark puffs her cheeks and gets angry, but she seems to have understood. Good, now it's time for practice.

..

"Like this from a stance with both arms firmly guarding the head move in as if you're going to tackle them, then use the trembling leg for an elbow strike!"

[Zupaaan!!]

"Ugh!!"

The mucus sandbag, struck by my right elbow using the trembling leg, bursts and explodes behind it, shaking the entire antechamber vigorously, and pounding on our eardrums.

"Hey! If you hit something like that, you'll kill a classmate! What are you teaching me?!"

Shark, perhaps terrified by its excessive power, approaches me with a pale face.

"No, this is just a demonstration. Don't use such techniques seriously, alright? Besides in real combat, your abilities might not even be half as effective."

When I teach, I teach properly. And I don't indiscriminately teach such dangerous techniques to anyone.

Although Shark seems to be in conflict with her Aikido classmates, I know she's the type to protect her classmates in case of monster attacks, so I teach her these dangerous techniques.

In that sense, I respect Shark.

"If you reach out, your joints will be manipulated and you'll be thrown away. So, just don't reach out. And also, Iron Mountain Leaning Body and Low Hip Push!"

[Zupaaan!! Zupaaan!!]

Struck by Iron Mountain Leaning Body and Low Hip Push, the mucus sandbag bursts into pieces.

By the way, the trembling leg and Iron Mountain Leaning Body are techniques of Baguazhang, one of the Chinese martial arts. It's probably a very famous martial art even in Japan, through games and manga. And Low Hip Push is a pseudo-derivative technique using the trembling leg.

"Incredible! That huge sandbag exploded into pieces in an instant!"

"Haha, impressive, right? You'll master all of these techniques as well."

"R-Really!?"

"Yes, really. And I've already arranged a suitable sparring partner for you."

"A sparring partner? Wait, is it Machi?"

"No, it's not her. Well then, since it's a good opportunity, let me introduce you."

Telling Shark to wait there, I head towards the door to the first basement floor. Hehehehe
