Kael and Taro continued training day after day Kael improved his control of power and unlocked new abilities such as completely erasing his present and the basics of teleportation, which consists of dodging. The day before Kael's last day of vacation, Taro challenges his student to a fight.
Kael is initially afraid but Taro says:
-Don't worry, son, I can take a few beatings.
Kael nevertheless enters the battle arena made of solid marble with some chips and cracks, which means that this arena had been used many times, Kael observes the arena and then observes his master who enters into a combat pose(something similar with the boxing pose but with one hand more continuous than the other), Kael enters his fighting pose(basically the same as the master but he has his arm stretched out less due to lack of experience), and then the master starts running in the towards Kael and kicks on Kael's head but Kael manages to block it with his arm, being thrown away.
The master takes the opportunity to say:
-Whoever leaves, falls or steps outside the arena loses.
Kael, upon hearing this, understands that he has to be more careful and the master explains something:
-Kael there are 2 types of battle in this world… one battle is of interests and the other type is of honor. This is not part of any battle that exists, this is training, which means you can fight with everything you have, you don't see with Analise that my power surpasses yours by light years.
Kael uses Analysis and realizes that his master's power is completely superior to his own and says:
-Then I can fight against Asserio.
Think for yourself:
(Well at least I'm not beating up some old man.)
Kael moved forward to attack with a punch to the stomach, but the master dodged it by elbowing Kael in the back, placing him on the ground. Kael, as he was in base form, used power to protect himself behind his back, and the master, realizing this, smiled and moved away. 
Kael stands up and says:
-I think the time has come to take this more seriously.
The next moment Kael activates his base form with all the power he has, his master looks at the difference in power and smiles, now Kael is in his normal form stronger than ever, looking into his master's eyes he prepares to attack. In seconds, with black smoke, Kael appears behind his master, kicking him in the side ribs, knocking his master off balance and falling to the ground. Confused, the master asks:
-I didn't teach you that... what was it?
Kael, still not realizing what had happened, asks:
-What happened? Didn't I teleport behind you and land a blow?
The master analyzing the situation thinks he understands the situation and asks:
-Have you always had that speed?
Kael responds:
-I don't know this has happened before during the universal event at my school.
The intrigued master asks:
-So it was you… your friend came by on the day of the event to see you. He wanted you to train yourself, but it seems like you came to me instead of me to you.
Thoughtfully, with his hand on his beard, the master says:
-I was warned of your power that instantly appears a black fire with a purple aura. The damage caused by this fire cannot be healed with any healing powers... only with time. How interesting.
Kael completely impressed asks the master:
-Do you know anything about this power?
The master responds:
-No... I don't know much about this power, just what he told me.
(The master had hidden information from Kael for his own good)
Kael's master, Taro, before he leaves says to him:
-Kael, you grew up a lot during this month. I want you to be careful from now on.
Kael nods and says:
-Don't worry about me, I'll be fine and I'll be back.
Taro, upon hearing this and thinking about his past, turns his back and goes inside crying, thinking
(Oh, how much Kael grew in a month is what he predicted, damn him, the Military Leader of Universe 5).
That night Taro decides to have a rest day with Kael before school to relax and invites Kael for a campfire conversation, Kael asks:
-Master Taro, tell me everything you know about my power. I saw you too thoughtful, I'm sure you're hiding something from me.
Taro looks at Kael impressed and thinks:
(I think I taught him too well or he was the one who learned such a thing...)
Taro decides to explain a little about what that is and says:
-Kael, as you already know, this power is something completely different from anything you experience and you have to be careful, the fact that this power appears instantly means that it flows in your body just like your fire power, perhaps in less quantity that in the Base form you don't understand, all I can say to you now is the same as what he told you "Until then, you will discover who you really are and you will know your name."
Kael is thoughtful and asks Taro:
-Master Taro, is there a possibility of this power getting out of control?
Taro confidently responds:
-If you can't control yourself, how will you continue forward?
Kael looks at the fire and interprets all this with a smile.
The two spend the rest of the night talking, Kael explains his current state to Taro and Taro comforts him by explaining that everything was destined to happen and that he now had to carry that with him until the end of time and gain strength enough to unravel the mysteries that would lie ahead.

After the battle and Kael's training is over, he returns to school and his second year of classes begins, while everyone else is out there celebrating the end of the year and enjoying the free time. Kael has been training hard to overcome his yes, and thus get closer to your goals.
On the first day of classes, new people enter Kael's class and one of them is Haru Rynar.
Haru becomes very interested in Kael because of his prodigy status and they convert:
-Hello, you are Kael, right?
Kael looks at him and asks:
-Who wants to know?
Haru responds:
Who wants to know? Haru,Haru Rynar.
Kael looks at him, becoming interested and thinks with a smile:
(Who specifically will this person be and why has he only entered school now)
And asks:
-Haru right? Why did you and a few others only enter the school now and for this class?
Haro somewhat melancholy replies:
-I wanted to avoid talking about it but I think I can trust you… my old school… was attacked and destroyed by the war that is happening with universe 8.
Completely serious Kael says:
-I understand, I lost my family, my brother, everything because of that war.
Haru with tears in his eyes looks at Kael speechless and Kael extends his hand and says:
-Together you and I will end this war, what do you think? 
Kael, with his hand outstretched, waits for Haru to act when a teacher arrives and asks what happened and Kael responds:
-He hurt himself, professor, but he's better now, his wrist had gone backwards when he tried to punch me during a training battle.
The professor believes Kael and says:
-Okay, but be more careful next time, the school's nursing services are very busy and we cannot interrupt with injuries like these.
Kael nodding his head says:
-Thank you for your concern, professor.
The teacher thanks him and leaves. Kael looks at Haru who seems more composed and asks again:
-Haru, you and I will gain power and end this war?
Kael extends his hand and this time Haru wipes the tears and gives Kael his hand, accepting the proposal.
The two trained every month after month and spent 2 years spending every day meeting and training in the school arena and Kael teaching Haru everything Taro had taught him so far, but as Haru hadn't had school in the last few years, times and was automatically passed on to the second year, so Kael taught him how to analyze power control, basic attacks like the "Power Ball" (basically it's concentrating power in the hand and creating a ball that when thrown explodes, in more advanced stages of power control it can be redirected by the user itself but our protagonist is still a long way from that), Haru managed to learn the base form but in a state where it is still somewhat uncontrolled and is weaker compared to Kael who can control his form is better than him but it's still not completely perfect, Kael also taught Haru dodging and the basics of teleportation using power particles in the air. They spent 2 years completely together, they were literally the two best students in that class, Kael being the strongest. because of his previous training and his mysterious power. What will it be?

When Kael and Haru were both the same age 12, but the entire fate of their plan changed when the two were talking in Kael's room and heard an explosion outside at school, Haru had been through this before and had been alert, but not it was an attack it was the recruiter from universe 5 who landed at the school and went to get everyone who could fight due to the universe having entered an extreme state and all men capable of fighting were needed between the ages of 10 and 80, this clearly being It's a crime for 12-year-old children to go and fight in a war, but the army in that universe was known for committing several war crimes, but giving very plausible excuses and always coming out on their side without any problems.
