One hour after they have found Ren’s dead body, Tetsu said Asaka to leave the hospital and go home. He would stay a little more. She would normally disagree with it, but right now she didn’t have the power to do that.

"Just be careful, Tetsu…"

"No need to worry, you know me"

She left and she went to her home, trusting Tetsu that he will be ok. He entered the hospital again, watching for one last time Ren’s dead body. He closed his eyes and walked on the hospital’s hallway, thinking.

I know he is here…Sendou Aichi is still in this hospital, I feel it… I will find you, I’ll take revenge for Ren’s death, Aichi…

While he was walking, cursing Aichi and himself, he noticed a surgery which had its door open. He looked around.

If I want to beat Aichi, I am going to need a weapon…

He entered the surgery, closing the door behind him. While looking around the place, he saw some medical tools, and approached them. Tetsu took a little knife, a lancet. He thought of it as the perfect weapon.

This is it….with this, Aichi will…

His thoughts were interrupted by a creepy annoying voice, the voice of Sendou Aichi.

"Tetsu-kun, what do you think you do? "

Tetsu shivered, hold the lancet tightly the lancet and turned around. Now he was face to face with his most hated person, the blue haired boy, the one who took away his best friend. Aichi was grinning, maybe because he had just won his little game with Ren.

"Aichi… " Tetsu whispered

"That’s right, Tetsu-kun… So, guessing from your face, you have already seen Ren-san, right? "

"You scum… YOU ARE GONNA DIE FOR THIS! "

Tetsu attack Aichi with his lancet, but the little boy avoided it by walking some steps behind.

"No, no, Tetsu-kun I have always thought of you as a smart person…you disappoint me… "

"SHUT UP AND DIE ALREADY!!! "

Tetsu was all fired-up. His eyes, his body, his blood in his veins, his very existence was focused only on how he would kill Sendou Aichi. The little boy laughed.

"I wonder, who is the one who should die? "

Tetsu looked the boy wrathful

"You are more stupid than I thought, Aichi…it’s obvious "

"You don’t understand me, Tetsu-kun… you don’t know… " Aichi said

"The only thing I know, is that I’ll kill you… FOR KAI, FOR MIWA AND FOR REN! "

"Please, put Kai-kun out of this… don’t you get it, Tetsu-kun? Why do you fight for Kai-kun, since you are not even his friend? "

Tetsu attacked Aichi again, but the boy avoided again the attack, also he landed on a little chair and sat on it, cross-legged.

"I’m not his friend, you say? Kai was always my friend, and it is my free will to kill you, so that he will finally live in peace from now on… "

"Stop it " Aichi interrupted "Stop it please. Why are you such a liar? You don’t want to kill me for Kai-kun, you want to kill me for Ren-sama."

"What?! "

"You think I don’t know what happened some years ago? Tetsu-kun, I know more things than you do" Aichi bragged about.

"Oh really?  How about tell me that after you paint this chair with your blood?!! "

Tetsu attacked once more, but when he reaches the chair, Aichi disappeared.

"What the… where… "

Aichi was nowhere, but his voice was still in his head.

"Tetsu-kun, Kai-kun had been suffering because of you all these years… "

"What? I have never done something that would hurt Kai! " Tetsu said.

"Huh… Then remember, Tetsu-kun. Do you remember that day, when Ren-san had Psyqualia, and Kai-kun decided to Cardfight with him to save him? "

"Yes and this fight wasn't finished "

"That’s right… this was the day when Kai-kun left from your city, remember? He couldn’t stay with Ren-san"

"So?? " Tetsu couldn’t understand what the little boy wanted to tell him.

"’’So’’? You still don’t get it? That day, you chose to stay with your psychopath friend, Ren-san, than leave with Kai-kun… do you understand what this meant for Kai-kun? His whole life was destroyed! He lost Ren-san, and when he was forced to leave, you abandoned him… since then, he has suffered from loneliness "

Tetsu stayed for a while with wide open mouth, but then he laughed.

"C’mon, Kai understands that I had to stay with Ren, so that he wouldn’t choose the dark path… "

"Really, Tetsu-kun? Because I think he chose the dark path. You didn’t achieve much, didn’t you? So, you are the cause of Kai-kun loneliness and depression, and you didn’t do anything to save Ren-san… but tell me, who is the one you care about? Kai, Ren? Or just you? "

"Shut up… "

"No, Tetsu-kun I can’t, you made Kai-kun suffer! And you don’t even apologize! You abandoned him when he needed you the most! "

"I NEVER ABANDONED KAI! "

"Then ask him: “Kai, how did you feel when I decided to stay with Ren, after you lost your parents, you changed school, lost you friends and Ren?” "

"I never…. Wanted to… " Tetsu’s mind was ready exploding.

"Tetsu, we both know the truth… "

Tetsu fell down and burst into tears. He never imagined how much bad Kai felt when he decided to stay with Ren. Also, he never managed to save Ren from Psyqualia.

"I…never wanted to hurt my friends… "

"But you did " Aichi’s voice said

 "Kai…Ren… I’M SORRY!!! "

"Nobody can hear you. You abandoned them, they abandoned you"

Tetsu stayed there, crying alone. He was under the control of Aichi’s voice.

"Tetsu-kun, you know what you have to do… "

Almost drown by his tears, Tetsu raised his lancet, and put it on neck.

"I’m coming to you… Ren… "

Some minutes later, the whole floor was painted by Tetsu’s blood, which was still floating from his neck. When doctors and police checked the cameras to find out what happened, the only thing they saw was Tetsu talking and screaming alone, even attacking with the lancet to the nothing. They decided that he got insane after his best friend’s death, Ren’s, and the case closed.
