As he said this, the black part of Heartless' right hand had already shrunk to the size of his entire fist.

"Take a good look at my full power."

This time, it was Heartless who took the initiative to attack.

Although Ryuto's steps were unsteady, he was able to dodge the oncoming flurry of attacks.

"It's useless. I can see through all your movements. No matter how hard you struggle, it's pointless."

As if to confirm his words, after predicting Ryuto's next move, Heartless effortlessly hit Ryuto's chest again.

"This is it, the final blow. This is my maximum strength."

At the moment of impact, Heartless increased his force, channeling all the power from his body and Kinesis into his right fist.

In an instant.

"Spu-"

A large amount of blood sprayed from Ryuto's mouth.

At the same time.

"Boom-"

The wall behind Ryuto suddenly exploded, not because Ryuto crashed into it, but...

It exploded without any object touching it, but if you looked closely, you could see some clues.

As the wall exploded, a hole, roughly the size of a fist, appeared on the wall.

Yes, when it comes to something invisible that can destroy a wall, it is a shockwave. When the power is pushed to its limit, along with a powerful punch, a shockwave is generated.

And that shockwave has a strong penetrating ability. It could penetrate not only walls, but even steel, it's not just a simple strike anymore.

Perhaps because of this, Ryuto's body didn't fly away like earlier, but remained in place, where he was hit, until now.

However, that place was now covered in blood. No, it was more accurate to describe it as a pool of blood.

"..."

Ryuto has not shown any reaction since spitting out blood.

"Tsk, did he just die like that? How boring."

Looking at Ryuto, with lifeless eyes and no strength in his body, Heartless clicked his tongue disinterestedly.

And the reason Ryuto hasn't fallen down yet is because of Heartless' support. Due to spitting out blood, Ryuto's body inclined forward and now he is in a state of leaning on Heartless' right fist.

"Well, it's finally over."

Saying this, Heartless tiredly retracted his right hand and then turned around, stepping forward.

With consciousness lost, Ryuto's body naturally fell backward as soon as its only support was gone. The body that was leaning forward now fell backward, probably because when Heartless pulled his hand back, the body's inclination changed from forward to backward.

In any case, in a state of unconsciousness without any support, Ryuto's body could only fall weakly backward. Then, suddenly, his back hit the ground.

It should have been like this, but the reality was...

As his back was about to touch the ground.

"Ugh..."

Ryuto, who regained consciousness abruptly, forcefully pulled his body up.

Afterwards.

"Cough - cough"

Before standing firmly, he lowered his head again and started coughing violently.

At the same time, blood splattered from his mouth, staining his clothes and the ground everywhere.

Then, he clenched his fist tightly, struggled but resolutely stood up again.

Meanwhile, the moving Heartless were obviously aware of this anomaly. They naturally stopped and turned around.

"......"

Witnessing this absurd scene in front of him, he gritted his teeth in anger.

Although that blow couldn't break through the diamond, even so, an ordinary person would have died several times already, but this guy...

Then.

"You damn heretic."

As he shouted, he stared at the other person with fierce eyes.

In response, the teenager just stood quietly in place.

Even though his face was covered in blood and his eyes were almost completely obscured by it, there was no sign of compromise or surrender in his eyes.

Those eyes, immersed in the blood, remained emotionless, only calmly observing everything in front of them, including the unfathomable darkness.
