I crawled on the ground to grab the sword that was given to me by my father, as soon as I grab the sword, I tried to stand up but, because of the wounds, it took me some time to do it.
I took a step back to make our gap wider after grabbing the sword.
"Why don't you just surrender already? You won't be able to win no matter what you do!"
The person in front of me is my opponent, and what he said is true I'm in a state where just standing alone is already exhausting.
Still, I won't give up easily, and that is the reason why this sword was given to me.
I close my eyes before calming myself and tried to remember all the training I did.
After a few seconds, takeshi opened both of his eyes before he prepared himself. Takeshi coated his sword along with his entire body of mana as he make an instance.
(Note: imagine this guy his body has blue mana too.)

John who is watching the scene couldn't help himself and said this.
"Are you an idiot? No matter what you do or no matter how many times you try the outcome is still the same."
"I don't care about the outcome, also you should prepare yourself and don't let your guard down"-takeshi with a serious expression.
" heh, do you think you can win? Anyway, that sword looks good, if I win this you will give it to me."- john.
"That bastard, if I'm on the arena now I would have cut him into pieces right here and now."- hayato with an angry face after hearing what john said.
" calm down, it's not part of the bet."- lux grabs his shoulder as he tries to calm hayato.
"Sorry but I can't give this sword to anyone, also, Tommy won the first round easily which is the weakest among us so, of course, I will win this too"
John be like:

Takeshi tried to insult john but ended up insulting Tommy as a result.
Tommy who heard this immediately got angry and said some bad things about takeshi and tried to cheer on the enemy.
"You bitch, I won the first round because I'm the strongest. Look here I didn't even get hit by that I don't know the name guy while looking at you a person who is about to die- mmmmhm mhm"- Tommy but Phil covered his mouth like a dad covering his son mouth who is about to swear in front of his mom.
'I feel bad for some reason' thought takeshi.
Meanwhile.....
"Achoo... I think someone is badmouthing me."-asval while being healed by a nurse inside the hospital.
Inside the school, there are many hospitals since the school itself is a city. These hospitals also help the school in case there is an emergency happening inside the Academy, and don't need to run or use a vehicle just to go to the nearest hospital.
Then asval just realized something.
" wait, what if kishimoto is thinking about what to do to me after losing to that kid."
Just thinking this a cold sweat run down from asval spine.
Back to the fight...
Takeshi used all of his mana in this attack. Blue mana around his body is raging like endless lava flowing.
As the mana gets stronger the surrounding area starts to shake.
"This must be his last attack"- lux after seeing Takeshi instance.
" I agree, he's in a situation where he could no longer move in the next minute, so putting his all in this attack must be the strongest technique in his arsenal right now." David agreed to lux.
'This guy, even with all those wounds he could still bring out his full power. I should be careful since that sword is suspicious.' Thought John with a worried look.
'I know I'm gonna win this but, what is this feeling.'- John before ordering his ghost knights to create a defensive formation.
"Defensive formation, black scale barrier"
With this, the ghost knights turned into black mana and surround John, creating a dome of barrier.
'With this, that guy won't be able to touch me. This barrier can melt anything in an instant since the heat of the souls are stronger than the fire itself. The moment that sword touched this barrier it will melt in an instant. I don't know anything about that sword, it looks cool but that's all there is to it. No matter what you say that sword is still made out of iron.'
Is what john thought with a grin can be seen on his face that looks like he's thinking something bad.
"Art of rain, 8th form"
After all those energies gathered on the same spot, Takeshi dashed forward without a second thought.
Swoosh...
Takeshi disappeared from where he is standing after dashing leaving a small crack in the surrounding area.
Imagine:

Cut... Cut... Cut...
In an instant, John's barrier was cut into pieces and penetrated inside as a result of slashing John's entire body in a second.
John who couldn't comprehend what just happened muttered a word before he falls to the ground unconscious.
"What just happened?"- John as he slowly falls to the ground.
" bullet rain"- Takeshi slowly put his katana inside the scabbard behind John's unconscious body as he called the name of the technique after cutting John and his barrier.
...
The entire audience was filled with silence after seeing John lying on the ground unconscious.
"No way, did he really lose? No way, but, how? That barrier can melt any sword and even a flesh of a human so, how did he?"- kishimoto as he couldn't believe what he is seeing.
" That sword is not just a simple sword created by someone"- gallahan with a smile on his face.
Everyone who heard this turn to gallahan with a confused expression on their face.
"You, what do you mean by that?"- asked kishimoto out of curiosity.
" that sword was given to Takeshi as the next successor of his family, the Yamato family. Of course, that's not just a simple sword considering the family he comes from. Did you know that the sword he is holding was created by the God of rain? Legend says that the sword was the one the God of rain used before he transcend into a god."- explained gallahan.
Hearing this everyone turn into surprised and shocked at the same time. They couldn't believe this, but, after seeing the fight, they believe what gallahan said is the truth.
The family Yamato is not just a simple family. Many people knows who they are since it's also taught by the teacher in the history class, but, what made them surprised the most is Takeshi and the sword itself, they couldn't believe that they actually be able to see the real one.
'The Yamato family, of course, I know them, how could I not know the family who was once the strongest family in my country, but, suddenly they disappeared after a rebellion, of course, they won and defeated all the people who betrayed them, but only a few of them live longer, and after many years no one knows where they are any more or where they live, the only one who knows what happened are the people who survived. The reason why I know this is simple, my family is also one of the strongest families in my country, not only that the person behind the rebellion was none other than my family and even if my father who was the successor did not tell this to us, the school would still tell this to the students except the rebellion part since no one knows what happened back then.'- thought kishimoto before he looked to the sword that Takeshi is holding, then a little smile came out of his face.
'I will definitely steal that sword, with that father will make me as the next successor.'
While kishimoto is thinking all of these, he didn't know that lux is observing him.
'That smile, I'm familiar with it, it's a smile of a person plotting something'- thought lux.
After using all of his strength Takeshi slowly falls to the ground, but, hayato helps him before he could.
"Thanks"- Takeshi.
" no need, we are friends, after all, it's normal to help a friend."- hayato gives a bright smile.
Takeshi couldn't help but to smile back.
With that, both of them went to the spot where everyone is watching the fight before they went to the hospital.
"That was a good fight Takeshi, I rate it 10 out of 10."- gallahan.
"Ahaha, I just got lucky"- Takeshi who receive the praise from gallahan.
" yeah, it was just a luck"- Tommy
"I think I agree with Tommy now."- gallahan.
" it's pure luck, if your enemy knows your technique then the one who's lying on the ground right now is probably you."-David as he also agrees with others just for fun.
"Aren't you guys gonna compliment me more after hearing that? Besides, I did my best"- said Takeshi loudly.
" don't worry Takeshi their just making fun of you, that fight was splendid"- lux gives a thumbs up.
"Anyway, we need to go to the hospital"- hayato cuts all the jokes aside as he told them that they need to go to the nearby hospital for a quick treatment.
Hayato didn't asked for lux because he probably forgot it.
Lux who heard this was hurt for a bit.
" There is no need for that!"- wilbur as he took a potion out of his small bag.
"Here, this is a healing potion"- wilbur as he handed the healing potion to Takeshi's hands.
Takeshi peek on the potion first to see if something weird was put inside it, but after seeing that there is nothing, he immediately drinks it.
With that, all the wounds started to close and the blood are starting to evaporate.
After a few seconds Takeshi was completely healed in a second.
" wow, what was that just now? It's completely different from the other potion I know. Did you bought it wilbur- san?"- hayato As he was astonished by the result.
"No, I made it"- Wilbur replied.
" ehhhh"- everyone.
"How?" Asked takeshi.
"Well, I like creating potions and I accidentally created a potion that can suddenly heal any wounds in a second." Replied Wilbur to all the questions in everyone's minds.
"Still, if you sold this potion it could make you a millionaire in just a matter of time."- gallahan as he observes the other potion from Wilbur bag.
" Sadly I don't have any intentions of selling it, I only plan to become a person who can create it."- Wilbur as he took the bag from gallahan sights.
"Anyway, thank you for healing me" takeshi appreciates Wilbur.
"That's fine we're all friends, it's natural."- Wilbur with a smile.
Hearing this made everyone smile and happy at the same time, they just couldn't believe they became friends in a short amount of time.
'Still, did he really forget?'- lux in the corner.
