4 Alpha and Epsilon/ Start of Training

[Epsilon: Hello?]

[Alpha has signed in]

[Alpha: Hello how are you?]

[Epsilon: I am fine, thank you. Were you the one that invited me?]

[Alpha: No. Much Like you I have been invited. The only difference is I am the first one.]

[Epsilon: Ho, I see. Are you also an admin?]

[Alpha: Very much yes, and you too I presume?]

[Epsilon: Indeed. It seems our titles have some hidden meaning after all.]

[Alpha: I thought so as well. But that aside, I wonder, where are you from?]

[Epsilon: Let me guess, you think we are not from the same world?]

[Alpha: Correct, but how did you guess?]

[Epsilon: It was a hunch. But I am from kuoh town.]

[Alpha: Did you just say Kuoh town?]

[Epsilon: Yes...]

[Alpha: The world of boobs and harem.]

[Epsilon: And it terribly stressed me for a good ten years.]

[Alpha: Should have been me.]

[Epsilon:...]

[Epsilon: wait]

[Alpha: wait.]

[Alpha: You are also a reincarnator?]

[Epsilon: You have also been Isekaied?]

[Epsilon: Yes.]

[Alpha: Yes.]

[Epsilon: Where are you then?]

[Alpha: Solo Leveling]

[Epsilon: You mean the world with an inexistent power system?]

[Alpha: You talk mad shit for someone in a world where people can power up just because they like boobs.]

[Epsilon: Point taken. That Issei better never approach me or else...]

[Alpha: Why would he approach you? Are you a girl?]

[Epsilon: Why do you think I was so stressed over being there?]

[Alpha: Yeah I can understand that. At least that world is easy, as long as you have some power.]

[Epsilon: You can't even imagine, I am half devil.]

[Alpha: You suffered...]

[Epsilon: Yeah, and I got the better end of the stick since my parents are affiliated with the Gremory.]

[Alpha: Are you in Rias's peerage or something? And are you trying to change the canon?]

[Epsilon: It's a bit complicated, but no I am not in anyone's peerage. I am more of a friend to her and Sona. Alpha canon has been changed since after I encouraged her to train, she become strong enough to beat riser even before coming to the human world.]

[Alpha: Good for her then. Also, did you happen to get a welcoming gift after joining the group?]

[Epsilon: Yeah.]

[Alpha: I see.]

[Alpha: I have to move, see you then. I recommend you to get familiar with the different functions.]

[Epsilon: Will do, see you.]

...

After that, he went to take a shower, brush, and clothe himself, and just when he finished he heard his sister calling him.

"Could you like, shout a bit less loudly?" He completed as he took a seat.

"The -nerve, see if I will bother with you next time." She would still do it next time.

"So- hm... did something happen to you overnight?" Something about him seemed to have changed, for a reason he seemed bigger? Taller? She couldn't put a hand on it.

"I made a strange dream, why?" Her senses were sharper than he thought. He didn't expect her to catch on it so quickly.

"No, never mind. I am probably imagining things." Is it because she was not sleeping well enough recently? Perhaps she should give more attention to her health.

"I see, so you are becoming crazy. I understand, don't worry I won't take you to a mental hospital but take care of you myself." Dokja nodded to himself.

"Crazy who? You are more likely to become one than me." Heejin answered she was not going to get walked on every time.

"Yeah, yeah, if you say so, anyway... What's up?"

...

Later that day when he was alone in the house. Dokja sat on his bed as if he was meditating and closed his eyes. He started feeling the changes in his body and mind.

But above all, he felt the chakra running through his body. It was warm and familiar.

Dokja ran through his mind and explored the new pieces of knowledge he received. How to best use his chakra, the most efficient ways, how to perform jutsu? how to walk on the wall and water? How reinforce himself physically?

Little by little all those knowledge was digested, and he found himself in the place of Raiden when he was doing all those things and started appropriating himself, Raiden's experiences.

The process took him around thirty minutes, after which he opened his eyes and exhaled as he came to a discovery.

"I have more chakra than I should have considering how much I integrated with him." He merely integrated with Raiden from the beginning until he was 4 years old and entered the academy.

While it's true that even at this age, the boy had as much Chakra as a Chunin, which compared to most ninjas his age was quite ridiculous. But that was understandable, since his soul had already matured, and thus his spiritual energy was much greater than that of anyone his age. And chakra being the fusion of the physical and the spiritual, it impacted the growth of his chakra.

And Right now, the obtention of Raiden's chakra pushed Dokja's body to create more, which was his own, the chakra resulting from his own physical and spiritual energy.

That boosted his chakra level from what should have been chunin, to around high jonin. That may seem like an insane boost but Dokja himself is also a reincarnator, meaning his spiritual energy should also be greater than normal.

"Although I have the chakra level of a jonin, my ninja art prowess is nowhere near that level. I have to train somehow." He started devising a training regime in accordance with the new knowledge he got and his own ingeniosity.

"Ninjutsu will be hard, it's too flashy and I have a high chance to get noticed, Shuriken jutsu, taijutsu, and fuinjutsu however is another matter. I can find a reasonable excuse for each one of them."

For shuriken jutsu, he could just say it is curiosity, for fuinjutsu a new hobby in calligraphy and finally for taijutsu, didn't change much from his daily exercise.

Of course, all of those excuses were only temporary, from his memory, a High Jonin should have strength at least comparable to an A-rank hunter if not a weak S rank.

With that much power, he would be able to protect himself and there would be no need to hide anymore.

Even more, if he learns the Flying Thunder God and awakens his dojutsu, it does not even have to be the All-seeing Eyes of God (he will temporarily it that way until I think there is a better name for it), the byakugan would be enough.

He couldn't also directly go register at the hunter association since he didn't know if their device specifically designed to track mana would be able to measure his chakra.

He also didn't want to flaunt that he had gained access to a new energy source able to give access to a new set of supernatural power.

So yes, the best course of action right now would be to remain lowkey until he could at least gain a level of strength appropriate for his chakra level.

"But's not like It would take a considerable amount of time or something. I already have a portion of Tobirama's knowledge, not only that I know the best jutsu to get stronger quickly." He smiled as his hand moved to make a rather popular sign within the naruto community.

"Shadow clone jutsu."

Puff*

A cloud of smoke was created and when it receded, four new identical figures resembling Dokja appeared.

"So you already know what to do." The original said while the others nodded.

One was going to go outside and buy some high-quality ink and scroll (paper?) To practice fuinjutsu.

One would sit and practice chakra control.

Two would practice Genjutsu.

And he would go outside and practice Taijutsu.

Of course, he was not going to do it before all eyes. He was going to reserve an entire gym.

As for where he would get that money? His sister was a successful B-rank hunter and member of the White tiger Guild, one of Korea top ranked guilds. Of course, they were rich.

He could at least afford that much.

Sadly, his sister doesn't really train often, so they didn't have any reinforced gymnasium in their house. It's a pity but, he couldn't anything about it for the moment.

...

In the gym he reserved for the next 3 hours, Dokja did his best to familiarise himself with his newfound powers. He did all kinds of exercises to get a measure of his strength and learn to control it. He tested his agility and endurance.

And he was not surprised at all to see that he was thoroughly superhuman.

After all of that, most of the 3 hours already went by, so he made it outside before finding a well-hidden spot and quickly make another hand sign and smoke emerged, encompassing all of his body.

"Transformation Jutsu."

When he came out, his hair was gold instead of black while his eyes became green, after that he went where he jogged most of the time since not many people went there.

Since unlike the shadow clone jutsu he had to manually undo this transformation and others couldn't force him out of it by merely attacking him, he planned to practice his ninjutsu in this form, pretending to be a hunter.

No one would be able to recognize him anyway.

When arrived he planned to practice one of his most liked but underused jutsu in the show. The body flicker Technique.

That technique was just too damn useful, but if not Shisui and Minato who actively use it in combat, it was overlooked by most others and only used to travel from place to place.

As he made a hand sign, he felt his chakra move through his body, and concentration increased in the tenketsu points in his legs. Not only that but also the rest of his body was also reinforced to passively support the high-speed movement.

With that, he moved, and his body seemed to have disappeared from sight as if teleporting before repeating a couple of meters away.

"This is difficult. The speed depends on the amount of chakra used and the mastery, but it's difficult to see while moving. No wonder it was so underused. Bare of having a dojutsu, the minimum requirement would be to possess an incredible reaction time."

The first was Shisui and the second was Minato. But he could also have the two. The byakugan should be able to help with that.

'Although the chakra used regenerated as soon as it was used, I still felt the chakra wastage. I need to get used to it and work on my chakra control. Chakra control is just that important. As without it, learning medical jutsu will be impossible.'

He was about to try again, but he remembered something.

'Wait, how can I be sure I don't have the byakugan? I didn't even try.' That was true.

So walking into a concealed spot, he closed his eyes, made a hand sign and directed his chakra toward his eye brain and eyes.

Five seconds later, he opened them and as he did, his eyes became featureless white and his irides expanded, the vein near his eyes bulged due to the increase in blood flow.

Dokja saw his vision expand almost 360 degrees bare the weak point behind his eyes, he could see things more clearly and even through them. His vision became way more dynamic as well, speeding up his perception by a level.

(I am giving the Byakugan the love it deserves and believe me I am going to develop it.)

"So this is the byakugan." The amount of information his brain was taking on currently was considerable, but it still worked just fine.

"Let's keep practicing and try to develop the byakugan at the same time." He spoke but before that, once again made a hand sign.

And seconds, after his byakugan was hidden behind a veil due to the transformation jutsu.

Of course, he was going to hide it, otherwise, after he start using it with his true appearance, it would be easy to connect the dot.

"Hm? Is that a dungeon?" With his extended vision, he easily caught on to the recently appeared dungeon. It seemed it was not discovered yet.

"Should I...?" He wondered for a second before shaking his head. "No, I should focus on my training first."

...

AN

So I was going to say, The all-seeing eye of God will appear as if it was an evolution of the Byakugan so much like the Sharingan and Mongekyu, the two can be used independently and deactivated if wished.

Next, as I say, prepare for the byakugan being explored and exploited a great deal, since it was severely underused in the show. Like bro? It can be used to expand and strengthen genjutsu. To release shockwave if proficient enough (Kaguya did it), to read fate (Momoshiki did it.), and much more! But no, no Huyga train it to the limit. It's all Kishimoto's fault anyway.
