In Naruto with the Naruto Gacha System

I opened my eyes in a forest, surrounded by complete silence. As I tried to figure out where I was, an unbearable headache hit me. It felt like my head was going to split open. When the pain subsided and I regained my senses, I couldn't help but curse.

"Shit, I've been reincarnated into the Naruto world, and it's during the Warring States period!"

I stood up suddenly, extremely shocked. I was a 21-year-old university student living in modern times. In my free time, I enjoyed watching anime, reading manga, webtoons, and fan fiction. The last thing I remembered was heading to meet my girlfriend when suddenly, in an empty street, a truck appeared and ran me over, killing me instantly.

After overcoming the initial shock, I understood where I was and let out a small laugh.

"Haha, really, the original owner of this body died because he was scared to death after falling off a cliff while being chased by a Kaguya clan member. Just as he survived the fall and tried to continue on his way, he saw the Kaguya clan member in front of him and died of fright."

Laughing at the absurdity of the situation, I started to look into the memories of the body's original owner and tried to determine the exact time period I was in. I was genuinely surprised to find out that this body's name was Myojo Tatsu. I was now 13 years old and living in the backstreets of Nensho City in the Land of Fire. But the most important part was that, apparently, Hashirama and Madara had just been born.

"Pfft, now that I think about it, those two godly figures are currently just a couple of snot-nosed brats, haha."

After laughing, I was about to run back to the city, but then I remembered that I had been chased by a Kaguya clan member in a forest so close to the city. With this realization, I went to a hill where I could see the entire city and saw that it had been completely destroyed.

"Great, on the day I reincarnated, the city is in ruins."

I noticed that it was starting to get dark. Realizing that there was no sound coming from the destroyed city, I decided to go there and leave in the morning. I was heading towards the road that, according to the body's memories, led to my home when I heard a sound that made me incredibly happy.

[Ding! System integrated. Congratulations, host, for acquiring the Gacha System.]

"Hahaha, yes! A system is great! But gacha, really? The day I reincarnated, the city I lived in got destroyed, and I got a luck-based system. Someone must be messing with me."

Beyond infinite dimensions and realms, a yellow sponge man with red eyes, each with three tomoe, sat on a large armchair, eating a big bag of chips. He was watching a floating blue screen. Upon hearing my words, he was momentarily surprised, then smiled while nodding his head.

"Hmmm, just as expected from someone reincarnated by the great Bob," he said and continued to watch the blue floating screen.

"Hmm?" For a moment, Tatsu looked at the sky. He had felt something strange, but it disappeared immediately. He shrugged it off and focused on the system.

"System, tell me about your functions," he said, and the system responded immediately.

(The functions are listed in Chapter 0.)

Tatsu thought for a moment and asked another question.

"System, what is the task I need to complete to unlock other worlds?"

[The host must kill 50 genin-level shinobi, 10 chunin-level shinobi, and 1 jonin-level shinobi. After that, a random world will be added to the gacha pool. The tasks will be updated to become more difficult after each completion.]

Tatsu nodded and continued asking.

"System, how will I use the power systems of other worlds? And I don't have chakra right now. Do I need to find a way to unlock it, or will you do it?"

[The host doesn't need to worry. As long as you command the system, your chakra will be unlocked by the system. To use other powers, the system will modify your body. However, don't worry; the system will prevent you from having the weaknesses of the race whose powers you are using until you fully transform into that race. But you also won't benefit from that race's advantages. All abilities will use chakra, and any items or skills that enhance other energies will enhance chakra.]

Tatsu listened to everything the system said and was quite happy. This way, he wouldn't have to worry about future abilities. Then he commanded the system.

"System, unlock my chakra."

Immediately, a warmth spread through his body, and he felt much stronger than before.

"System, you said I would receive gacha points every month. Do I have any gacha points right now?"

[Yes, the host currently has 1 gacha point and 1 free spin. For the first spin, you are guaranteed to get at least a B+ level item. Do you want to spin now?]

Tatsu grinned and said, "Yes." Then, two wheels with '?' marks appeared and started spinning. After 10 seconds, they stopped, and a screen appeared in front of Tatsu.

[Tenseigan] S

[Dark Release] A++

Upon seeing this, Tatsu was initially shocked. Then, black diamond patterns appeared on both his hands, overlapping each other, and he felt a refreshing sensation in his eyes. His chakra increased immensely, and a wide grin spread across his face.

"Hehehehe, as long as I'm not lazy in the future, it's certain that I'll reach Six Paths level. System, what's my current level and what elements do I have?"

[Ding! While the host's chakra level is at mid-level Kage, due to having no battle experience and not knowing any taijutsu styles, the host's combat level is between Jonin and Elite Jonin. The host currently has Fire, Lightning, Water, and Yin nature transformations.]

Tatsu was satisfied with his current power. As he thought about his future plans, he set off towards the ruined city.

This is my first time writing this, and the translation was done by ChatGPT, so there might be some mistakes. If you see any areas that are lacking or flawed, please let me know. I'm open to criticism as long as it's not too harsh.

And yes, Tenseigan and Rinnegan are at the S rank. To give you an idea of the level difference: A+++ is the Eternal Mangekyou Sharingan, while the regular Mangekyou Sharingan is between A+ and A++. Dark Release is A++ because it is highly versatile and powerful in defense, offense, and support. Higher ranks will appear as more worlds are added. In the Naruto and Boruto series, there is nothing above SS rank, and for higher ranks to exist, my future plans need to come into play. Otherwise, there won't be anything above SS rank in the Naruto/Boruto world.
