DxD: Adventure of Lifetime

I never thought that I would be awake in this place. What kind of place do you ask? A fictional place. I get reincarnated into a world where Gods and other mythical creatures exist. I was a young man in his mid-twenty who celebrated his birthday by getting drunk.

Sadly, it was the last birthday of my previous life.

I died from lightning. That's right. I was struck by lightning. It was a quick and painful death. Luckily it was quick, but it was still painful.

After that, there was nothing fancy because when I opened my eyes, I reincarnated as a baby.

And just like any reincarnation story, I get some kind of cheat. I don't know what it is called, but when I reincarnated as a baby, a screen appeared in front of me.

|Randomizer System Activate|

|You will be given your first power! Randomizer…|

|Congratulations! You get Haki!|

That's right. I got the power of Haki from One Piece. Because of my baby body, I could not train my other two Haki, but I can still train my Observation Haki. The system is kind enough to give me the basics of each Haki, and I did not need to unlock them.

I already have them, but they are in a very weak state. For the past four years, I have trained my observation haki and a little bit of my armament haki. I don't want my family to see my skin change into pitch black.

Speaking of family. I'm born into the Ryuudou family in Japan. My name is Reikan Ryuudou, the firstborn son of the Ryuudou family. My family is not your ordinary family but a family of Onmyouji.

That is the reason why I know what kind of world I reincarnated into. My family stays in Nagoya, and we have a few connections with the Youkai faction. When I was three years old, my parents took me to Kyoto, and I met the leader of Youkai, Yasaka.

When I see the big-boobs fox in front of me, I know that I am reincarnated in the DxD world. The world where the strong rule the weak and the one who has strong enough perverted energy will grow very strong at a very fast rate.

Anyway, as I'm reaching the age of ten, my family has a tradition. My family is unique, you know? My family is not supposed to be an Onmyouji family because we did not have any mana core inside our bodies.

We get our power from the blessing of the gods. Because of this, every fiver-year old child needs to go to the elder, and the elder will take them to a special pool given by the God Hachiman.

"Come, Reikan Ryuudou. The ceremony of blessing is about to commence."

It looks like I'm the only one who does the ceremony. Well, I guess you cannot have a lot of five-year-olds all the time. I take out my clothes and put on the ceremonial clothes. After all the preparation is done, I quickly follow the elder, who leads me to a pool.

"Submerge your entire body for a few seconds."

I nod my head and get inside the pool. I submerge my entire body inside the pool and wait for a few seconds. Nothing is happening.

"What a waste. A child from the main family did not have potential. Hmph. Take him away."

I can see them coming, but they are too fast for me. I can feel a slight pain before darkness consumes me.

~Sometimes later~

I'm in the middle of a forest when I open my eyes. Well, it is not like I don't expect this.

I look at the screen in front of me and sigh.

|Get kicked out of your clan (Completed)|

|Generating reward… Randomizing…|

|Congratulations! You get a Training Room!|

What the hell is a training room? I look at the ring in my hand and wear it. After I wear it, I know how it functions. This training room is a pocket dimension where I can train my power. It can be modified to my desire and even has a function to increase its gravity.

The other function is a healing ability. It keeps my body at its peak and makes my body adapt faster. That meant I did not even need to eat as long as I was inside this place. It was a perfect training place.

However, this powerful ability only lasts for three hours, depending on what kind of modification I put into this room. The more complex, the faster it becomes. Lucky for me, three hours is a lot because of the last abilities of this room.

For each hour outside, it is ten days inside. That means I have a month to train inside this room if I only use the basic function. Sadly, the Training Room has a cooldown of twenty-four hours.

Well, I have a place where I can train. Now… What is my goal?

I look at the moon above me and sigh a little. I don't know what to do now. I'm just a normal office worker that works every day like a drone. It was a boring life, and the only exciting thing happened when lightning struck me.

"Adventure."

Yeah. That's what I want before I die. An adventure. An endless adventure. Let's explore this world and be free! I don't want to be tied down like before and enjoy the world! Let's explore the world and see what it is like!

"For now, I need to train my body and haki."

I push a little bit of my haki into the ring and appear in the middle of a white room. I close my eyes and imagine something inside my head. I imagine a young man with black hair and a scar on his chest. He wears an open, long-sleeved red cardigan with an unbuttoned button showing his chest to the world.

This young man is Monkey D Luffy, my training partner.

I bow a little and say.

"Monkey D Luffy. I will be in your care."

"Shihihi!"

I widen my eyes when I hear the clone in front of me laugh and start to throw punches at me. I can see the punch and quickly dodge the attack. However, Luffy did not let me even breathe as he punched my stomach.

"ARGH"

I look at him standing there with a grin on his face. I slowly stand up and say.

"Bring it on!"

|3rd POV|

For seven days (Inside the Training Room), Reikan trains his Observation and Armament Haki inside the training room, and he grows stronger. Reikan grit his teeth and flare his observation haki to the max.

He can see them. He can see the flurry of punches coming at him. However, even if he can see them, he cannot dodge all of them. His body cannot keep up with the attack. Because of this, he covered part of his body with armament haki when one of those punches almost hit him.

He can cover his entire body with haki, but not only will it be weaker, but it also defeats the purpose of the training. He wants to have control and power rather than just power.

"Urgh. Fuck!"

Reikan once again gets thrown away by Luffy's punch.

"Bloody hell. I bit more than I can chew. Even though I ask for Luffy when he has just finished his training with Rayleigh he is too strong. I need to start with a smaller partner."

Luffy disappears in front of him and is replaced by his younger version. This version of Luffy is when he just defeats Enel.

"Here I come!"

"Shihihi!"
