11. Black Oni Gate Sword Art

„Well, let's get started. My sword art, the Black Oni Gate Sword Art, is a very encompassing sword art, that is more strength oriented. It has 7 moves, that can be used individually, but are even more powerful if used in succession. They are,

First move – Sieging, it is the second fastest move of the seven and focuses more on a wild onslaught of sword strikes, that are used to overwhelm the opponent with fast and wild strikes, until he doesn't know were to defend anymore.

Second move – Breach, a move that is focused on overwhelming the opponent with a single brutal strike, destroying any defense the enemy may put up with raw strength.

Third move – Opening, the most balanced move of the seven, is used, to create an opening in the defense of the opponent with high skill, and a good eye for the faults in the opponent.

Fourth move – Enter, is the fastest move. Its a simple, but powerful and fast thrust, that is used to exploit a any openings that the enemy may show, but its also a move that will show an opening too after the move is over, that can be exploited, so this move should only be used when you are sure to hit.

Fifth move – Closing, is used for counterattacking the enemy, the use is pretty simple, you wait for the enemy to attack, deflect the attack and then use the flaw to attack yourself.

Sixth move – Barricade, is to focus all of your energy within yourself, thus strengthening your defense. Its also a move to store energy for the seventh move.

Seventh move – Destruction, like I already said to use this move at full power you first have to use the sixth move – Barricade, after storing every power you have and completely focus, you burst it all out in one instant, in order to destroy anything that stands in your way. But the drawback of exploding all your might in a single move is also huge, as it creates a massive opening, that if you can't defeat your opponent with this, then you will likely be defeated or killed instead. So you should be really careful before using this move,and only act if you are either confident or desperate."

After he finished the explanation he also demonstrated the moves but not on the training field. He instead took me to the beach and demonstrated the moves there.

And I was really shocked by what I saw, the move he used on that day three years ago, was only the first move, and that was really shocking, as the real first move, was with this power of attack, but he fired tens or even hundred such moves in the span of two to three seconds.

The second move was like Master said, a culmination of raw power, if a single slash of the first move could split the sea a hundred meters long, then the second move could split it for about a kilometer or two.

The third move wasn't that special, at least from the surface, it could only show its real value when in combat with another person. He also showed me once, when he told me to attack him and my sword was instantly sent flying, but as I was too weak I couldn't appreciate the move, as Master could sent my sword flying even without it and just in normal combat.

For the fourth move I only had one word, fast! It was way too fast, I normally couldn't really see my Masters moves anyways, but I would at least be able to tell that he moved, but this move, I didn't know when or how Master moved, all I saw was the sea suddenly splitting in two for around 600 to 700 meters out from our position. Which was creepy as hell.

The fifth move was also a bit underwhelming as I again was too weak to let my Master show its true value to me, side it was a counter attack and I had to attack him, he simply moved his sword lightly and my sword was again sent flying and he attacked me, of course he only went through the motions. So I wasn't hurt.

The sixth move was the same, I only saw my Master take a defensive position, and his aura vanishing. Nothing special.

But the seventh move was different.

This time it showed how powerful my master really was. I think the real reason we went to the beach was for this move.

After Master converged his aura and everything he had inside, he became like the calm sea, the calm before a storm to be precise. As when he used the seventh move, all that aura and all he had focused on his inside suddenly burst out through his sword. It was a truly apocalyptic scene, and if Master hadn't controlled it, then the even the slight traces of his aura that escaped wold have been enough to kill me ten times over.

After unleashing the strike, the sea split for as far as my eyes could see. And that was pretty far, I was after all looking at the sea, where nothing obstructed my vision. And I think I at least could see for a good ten kilometers. And the sea was split all that way. Truly terrifying, if Master used this move in the island, then it would split the whole island into two pieces.

But this power also had some drawbacks, as I saw my Master panting while leaning lightly on his sword.

This was truly a terrifying move, that served as a last resort. A true trump card.

...

Now that day was already two years ago and I am now thirteen years old, and in these last few years I didn't grew that much, only to around 335 cm. This growth over the last 5 years wasn't hat much, but I think that in another year or two I will hit my final growth spurt, after which I will reach my final height. And thinking about my father, who reached 666 cm and my mother who was quite big too, at around 450cm I think I will reach anywhere in between them.

Well I will have to wait for a few years to know the final answer to that.

Next let's talk about my progress, first my fruit. I trained daily with my fruit and around half a year ago, I had another breakthrough, I can now stack three Domains together. With this my range for them were now as following, one domain 120 meters, two domains 90 meters and three domains 50 meters.

For the duration, like always I take the Heat Domain as an example, if I use only the Heat Domain, I can hold it for nearly 15 hours, after using a second it will be two and a half to three hours, and with three domains at the same time, I can hold them for at most thirty minutes.

The power naturally went up, and now when I use my domains, even granny will have to use haki to resist easily, of course that is also caused by granny slowly turning weaker over the years, as her old age slowly caught up to her, but one should know that granny had served my family for the last three generations, me, my mother and my grandfather and she is already over 80 years old.

My master is over 90 by the way, but he is stronger than granny, and he kept training even when he is now so old. But that isn't he case for granny, as she focused more on serving my family.

As for my other domains, my maximum usages of the Teleportation Domain went to 15, the gravity enhancement of my Constriction Domain went to 25 seconds, and my attack domain, reached 400 normal attacks being able to be projected, but this is also only for the normal attacks, if I used some of the moves of the Black Oni Gate Sword Art then it would plummet to only 30 moves.

As for my Explosion Domain I could now use it 5 times and the Loop Domain only consumed 15 percentile of my stamina now. I could now use the Compress Domain for around an hour at full strength, which would compress the space of 120 meters to 300 meters.

I even came up with a new domain, the Mist Domain, this domain is filled with mist, so that the enemy can't see, and since it is my domain I would be able to still sense their position, giving me an overwhelming advantage.

I actually created this domain through an accident. As I was experimenting with the combination of my domains. I was testing the combination of my Heat and Cold Domain. This was actually not the first time I did that, but this time was different, as it was raining. Rain is really my lucky weather for discovering new things for my domains.

Anyway as I was saying, I was testing my Heat and Cold domain in this rainy weather, and as I was concentrating on trying to do anything useful with the combination of the two, mist slowly formed around me and even before I noticed it I was completely surrounded by mist dense enough to make me unable to see my outstretched hand.

This gave me the idea for the Mist Domain, as loosing sight would be a big burden for anyone without observation haki.

I even made a happy discovery. The power and consumption of the domain was already on the same level as if I had a principle for this domain.

How I knew?

Instinct!

In the one piece world the instinct of a person was really scary and accurate most of the time.

And my instinct told me that even if I made a principle for the Mist Domain, it wouldn't really do much, except if I had some qualitative leap in my principle generation.

Is is also something I learned. The principle for my domains had different levels and if I had no qualitative leap in my explanations, then I would be unable to amplify my domains past a certain value.

For example, if my current domains base value was 1 then after adding a principle to it it would become 1.5 or 1.6, and if I want to strengthen it further I had to either increase the base value, or I had to have a qualitative higher principle, so that I could amplify it higher.

And the reason I came to, why I didn't red a principle for my Mist Domain, is that I already a had a principle for it. The way I created the domain was different then the others, where I would simply think of the effects, and then made it. This time I created the domain by combining two domains and the environment to create this domain. As such I already had my principle.

Something else that's interesting to mention is, that my Mist domain is a bit dependant on my surroundings.

So if there is water around me or in the air, the domain will be strengthened and use less stamina.

A domain cast on a dry day, without any water nearby I could hold it for at most 10 hours, even if I did nothing else but to keep it up.

Even the density of the mist would be higher then when there was water around, as without water the visibility was around 4 meters, but the more water inside the Domain the less the visibility, until one wouldn't even see the outstretched hand before oneself.

At the same time, the more water there is the less the stamina consumption and the longer I can hold the domain. At the maximum output I can even last longer than my normal maximum of one domain, at around 20 hours.
