And so, Kai tried to run away with Yuna.
He grabbed her hand and looked into her eyes with such intensity.
Then, with a determined tone of voice, he spoke:
"Yuna, we must get out of here. Our savior is waiting outside." Kai said, trying to reassure Yuna.
She didn't even speak.
She just looked into Kai's eyes with a strange feeling of warmth invading her heart.
In that moment, she was seeing Kai as her savior, the hero who risked his life only to save her.
She didn't listen to his words; she was too stunned and lost in her million thoughts, filled only with Kai.
She nodded instinctively, and Kai smiled at her.
After that, they started running towards the end.
Luckily, Kai memorized the entire path from the beginning to the end, so he knew where he had to go.
They kept running through the infinite corridors of that building while anxiety was filling their whole soul.
During their run, Kai received a message on the phone from Sakura, saying that she was waiting outside right where they entered.
The text also mentioned the fact that Yuki Nakamura was coming more rapidly.
And so, Kai sped up his steps along with Yuna.
After some minutes, they found themselves at the starting point where two men were lying down on the floor, senseless and tied up.
Kai had a confused look on his face.
The sound of gunshots was still audible from his position, and so he was wondering how the two men didn't wake up.
They were in the same position as before. They didn't even move an inch.
Kai, guided by curiosity, stopped for a second and leaned down to see the men closer.
He then placed two fingers below their mandibles; specifically, he placed his fingers near their jugular veins to control their heartbeat.
His fingers felt very cold and… there was no sign of heartbeat.
Hina killed them with a chop and broke their neck.
And then he realized why she tied them up:
Hina tried to fake the things that they were alive because there was an officer with her.
That would've explained other things…
Hina probably also knew that the police officer was about to die.
She calculated even this possibility…
A drop of cold sweat fell from his face to the floor.
Kai's eyes widened, and he stood up.
He then looked back at Yuna and faked a smile to reassure her.
She asked: "What's wrong, Kai?" With a worried expression.
Kai's smile widened even more as he tried to remain calm, but his hands were shaking a little.
He touched a dead man for the first time in his life.
"N-Nothing, Yuna. Let's get outside." He said, while grabbing her hand and starting to run again.
As soon as he arrived at the exit, he noticed a strange thing.
The exit door was already open.
He then stopped in place and turned his head towards Yuna.
"Stay here and don't move, Yuna." He said in a direct, cold tone of voice, while taking a knife out of his pocket.
Yuna nodded and took some steps back.
Kai then looked around the main room where he entered.
All of his senses were on alert.
He was ready to strike mercilessly and without thinking twice.
He raised his knife.
He then slowed his breathing to calm his body and took a few steps forward.
The only sound that was filling the room was the sound of his breath.
Yuna was still staying behind him just like he ordered.
Despite her fears, the strange feeling of warmth deep down in her heart started to reach other parts of her body.
She was looking at Kai with a bit of admiration in her eyes.
She was truly happy and overjoyed that somebody risked his life for her…
Love… maybe. Is it love?
A big question with an uncertain answer.
Kai was still slowly walking forward, and you could literally hear the sound of his heartbeat.
He swallowed some saliva before looking at every corner of the room.
Then, a strange smell of beer and onion invaded his nose.
The scent was coming from his right.
But when he turned his head, he didn't even have the time to blink an eye…
…That a strange big man assaulted him from the shadows.
He literally jumped on him, making him fall on the floor.
Kai didn't even have the time to react, and he rapidly found himself standing down with a big man on top of him.
Yuna screamed in terror.
"KAI!!!" She screamed, trying to step closer to give him some help.
"DON'T COME CLOSER!" He shouted while looking at her.
The man on top of him didn't speak a word.
He had such a very angry and violent expression on his face.
He was ready to beat Kai senseless.
The man seemed like he was lost… like he didn't know what to do.
But the only sure thing was that he was about to land some deadly blows on our young protagonist.
"Who are-" Kai tried to ask, but the only answer he received was a punch.
Luckily, he managed to parry it with his forearms, but the hit was so strong that he felt a lot of pain.
His knife fell on the floor, next to his left ear.
Yuna shouted again.
"KAI!!!" She shouted, running closer to him.
Once she was close enough, she tried to land a kick on the man's face, but she failed.
The man blocked the hit and pushed Yuna away, sending her into the wall.
The hit was strong, and Yuna's eyes widened in pain.
Her body was still fragile, not like Hina's.
After seeing that scene, Kai's soul started to burn in anger as he tried to land a punch on the man's face.
But his fist didn't reach his face; instead, he blocked his punch and started to strangle the young man's neck.
Then, Kai took a rapid look at his friend Yuna and saw her eyes slowly closing.
Yuna passed out…
Then, something just snapped inside of Kai.
The sight of his friend being hurt like this actually unlocked something in his soul.
But not a positive thing.
Kai stopped thinking with his heart, and only survival instincts took the better of his soul.
His eyes became a darker shade of blue, and he looked into his aggressor's eyes.
The man's grip on his neck was so tight that he couldn't even breathe anymore.
He was on the point of passing out too.
He tried to break free but with no success.
The man on him was too strong.
"No survivor… no intruders… that's the rule…" the man slowly repeated while strangling Kai.
Then, guided by survival instincts, Kai's left hand tried to reach his ear.
It was only a matter of seconds before he lost his senses.
But then… after a few seconds, he finally grabbed the knife from the floor and did something he never expected to do.
With all of his remaining force, he managed to penetrate his aggressor's flesh with his small knife.
He hit one of the most vital points of the human body.
He landed a perfect strike on the man's neck.
Kai did it.
Kai did it.
He killed a man; his hands were now dirtied by blood.
The man's eyes widened when he received the hit, and the grip on Kai's neck rapidly released.
A river of blood came out from the wound as his body fell on the floor senseless, with some muscular spasms after exhaling his last breath.
After that, Kai took a deep breath like he hadn't breathed for months, trying to catch more and more air, while the adrenaline was flowing in his veins.
He rapidly stood up, not caring about the fact that he just killed a man.
Just a rush of adrenaline, maybe…
But deep down he knew that this thing would've just traumatized him.
Then, without thinking twice, Kai walked close to Yuna and picked her up.
He then ran outside and found Sakura waiting right at the entrance.
As soon as Sakura saw him, a wide smile appeared on her face.
But didn't she see the man assaulting Kai…?
Who knows…
Sakura ran towards the young man and noticed that a cold expression replaced his usual friendly expression.
And for that exact reason, she didn't ask any further questions.
She just opened the door of her car so that she could save Yuna.
As soon as Kai placed Yuna in Sakura's car, he immediately turned back and headed towards Hina's location.
He just waved at her and said, "Thank you," in a cold voice before entering the building again.
Sakura didn't say anything.
She probably already knew that any of her words wouldn't have changed anything in Kai's spirit…
But she also noticed the blood on his left hand, and a wave of confusion mixed with a small glimpse of fear invaded her heart.
"No… he didn't do anything… he's a good guy…" she said, before getting into her car and starting to drive away.
Sakura also perfectly knew the place, and she drove in a different direction to escape the police.
In a matter of minutes, while Kai was inside, an entire army of police and special forces arrived at the place.
The first one to arrive was… Yuki Nakamura.
Kai had to act very fast and run away as far as possible before his life would've been ruined forever.
