Before we start:

I add new thing! Yay! And now seriously. To make it easier i add emotion, (like smile or blush and something like it) if i can call like this. If not you can correct me. Anyway, it will be name like this:
[Something]

And now have fun:

*That demon is.... WAIT! That's impossible...* Gakusei thought
"What? You look like something happend. Do you finally understand that you have no chance against me?" Demon said to him while smilling to him
"Do you really do that? Do you know how many people was suffering beacuse of you? You don't remember me?" Gakusei said ignoring what he was talikng about
"What do you mean? My human life? I don't remember anything, but i don't care. Im now your enemy so FIGHT ME!" Demon said to him
"DO YOU THINK I WILL FORGET ALL OF WHAT YOU DID?!" Gakusei looks like he was crying but he rush to demon "ALL OF THEM SHINDA, MY FAMILY, MY HOUSE! I WILL NEVER FORGIVE YOU! I WILL KILL YOU, KAZOKU! Gakusei now attacks a demon
*Kazoku? What are he talking about.. it doesn't matter. Damn,he is more powerfull than last time i can't hold him for long.* demon thought. Gakusei while attacking him heard in his head all voice of someone important for him "promise me that.." Shinda said to him "Fight until someone will win" now Kazoku
"Gakusei i will be always with you" said person that Gakusei didn't recognize at all. *Who is it? Is it....auch that damn demon that was close i need to concentrate* Gakusei thought now he was bleeding a little from his arm, beacuse demon hurt him with his sword. But for Gakusei it doesn't matter. He was still rushing to Kazoku, so he can only block Gakusei attacks. "KAZOKU ITS YOUR END!!" Gakusei shouted to demon
*Infinity breath:Third Technique -Infinite spin* now demon want to run beacuse he understand that he have no chance against him but it was to late. Gakusei was faster than him. Finally Gakusei shredded him.
*I told you its your end* Gakusei thought, but than he fell on floor and, starts cough a lot of blood. *Is it my end to? Well im finally win with you Kazoku.... NO! I will don't surennder so easelly.* Gakusei use regenerate breath *It don't heal me at all but i can now move* Gakusei thought but now he heard an evil laughter. *What?! Its impossible i sure that i cut him to litlle pieces* he thought
"What did you say? That its my end? How i see you are barely alive. Do you think that i will come with my true body? You are dumber than I thought. Now i will kill you easelly beacuse you don't have strength to fight. Don't even try to detect me. Im good at hiding me. Now say goodbye" he said to Gakusei *What?! I must do something maybe im barely alive but i have do this... But i can feel his aura i always was good at it so its no problem for me...but maybe its his clones i have to this, i have only one chance* he thought and he grab his katana. But then he feel a big aura rising and then in front of him show a very big demon "it's biggest clone i can create, lets see how long you can survive." demon said. Gakusei smile then but he can't even move so he throw his swords into a building,and then cut he cut them in half. So 2 building was falling on demon clone. When they fall demon can't move so Gakusei now want to do his plan *Now i know which one he is, and the best is that that he can't make clones anymore beacuse that big is still alive anyway. TIME FOR MY LAST MOVE.
#INFINITY BREATH: SECRET TECHNIQUE-INFINITIES CONNECT#
Now Gakusei was just in one second in front of he. Demon was surprised so whem he fanally came to his senses, only what he can do was just blocking. But it didn't take long, beacuse Gakusei was to fast for him now. Then Gakusei coughed up blood *Damn, i must end it now maybe its looks like i wining, but it won't take long beacuse i'm at my limit.... I WILL END THIS NOW!* He thought, and he starts yelling. After a while it was tie beacuse demon was now lying on the floor. But Gakusei didn't have time to move his body so he was standing like that, and he was even harder cough up more blood *damn,i still don't end this technique it was dengerous to use it. I must faster cut his head i still have strength to do it, or he will kill me.* he thought, but then he looks on demon *its still Kazoku i cannot kill him. It was my best friend i can't kill him even when i know that he kill my family and Shinda i cannot do it, but....but if i don't do it he will do it
What i should do? What?* He thought. So he was constantly arguing with his thoughts, but then Kazoku had regenerated and was about to deal him a fatal blow, but then sunrise has come. Now Kazoku turned to dust Gakusei mentally broke after it all.
*Why did he agree to this? After all, he had a choice ... He must have.* Gakusei thought. *If I had been as powerful then as I am now, it certainly wouldn't have happened.* Gakusei continued to think, and he blamed himself and grieved for a while, but from a distance he noticed Kenshi who was looking at it all. The boy Gakusei saved was looking at him. Gakusei, despite his physical and psychological wounds, got up, took Kenshi and they went to the headmistress's house.
But there was still Kazoku who was slowly fading out.
