As an Uchiha I became the Jinchuriki of Senju Tobirama

For Black Zetsu, it was not normal to see an Uchiha with such a genuine and carefree expression like Kazuki's.

Kazuki also nodded slightly, approving of Black Zetsu's performance. At this moment, Black Zetsu looked like a beautiful girl next door, and Kazuki couldn't detect anything unusual.

Kazuki looked at the decoration of the house, admiring.

"Obito, your home design is lovely. I love the vintage touch you've given it. Did you hire an expert for the decor?"

Obito laughed and proudly replied: "It was all Rin's idea! Isn't it great? This is a style that is all the rage in the Land of Fire."

Kazuki nodded, giving a thumbs up in approval.

"It's really impressive. This particular mural looks like an ancient piece of art. It has an amazing level of detail."

Black Zetsu's heart skipped a beat, but Kazuki didn't continue talking but continued chatting with Uchiha Obito.

Is there anything wrong with this mural? No, it's just a decoration style.

For an unknown period of time in the past, Black Zetsu had no fixed place to live and didn't need a home. The Mayfly Technique allowed it to use the world as its bed.

Ever since Black Zetsu had started living with Obito, he had grown accustomed to the idea of ​​having a home and the feeling of comfort it provided. He had arranged this space in his own style, adding a touch of antiquity.

Although Kazuki's comment sounds like a genuine compliment, but combined with the strangeness of his chakra, Black Zetsu always feels that something is wrong, as if he is pointing it out...

Is this a coincidence?

Obito and Kazuki chat happily, the two of them talking about everything, like good friends who know everything about each other.

Black Zetsu, who occasionally participates in the side, feels heavier in his heart.

Black Zetsu has seen it...

In the conversation between Kazuki and Obito, the simple Obito seems to be the one doing most of the talking, but he is completely directed by Kazuki.

Obito even exaggerated what Uchiha Setsuna said about Kazuki.

How long has it been since then?

Not long ago, Black Zetsu still clearly remembered that Uchiha Obito was still shouting the slogan of taking back everything and wanted to defeat Kazuki. How is it that now it seems as if he never even had that idea?

After chatting happily for a while, Uchiha Obito grabbed Kazuki's arm.

"Don't go yet! Stay for dinner. I'll prepare something myself."

"Don't worry, my cooking skills are very good, Rin taught me everything, you guys chat for a while, I'll go cook!"

Obito Uchiha rushed into the kitchen, and Kazuki turned around and smiled at Uchiha Rin.

"You are so lucky, Rin, to find a boy like Obito who loves you deeply and is simple, and he is also a genius of the Uchiha clan…"

Obito was in the kitchen, and he had been eavesdropping on the conversation between Kazuki and Black Zetsu, and he grinned when he heard the compliments.

As expected of Kazuki!

Uchiha Obito couldn't help but feel ashamed. Kazuki was so upright, but, he had doubted him like that before.

Determined to thank him, Obito added more meat to the dish he was preparing.

Black Zetsu smiled in a standard way and stared at Kazuki: "Thank you, Kazuki-kun."

Kazuki shook his head and said with emotion: "Obito is like a brother to me. I'm relieved to see that he has someone like you looking out for him and that you two get along so harmoniously. I'm glad that you're gradually forgetting about loneliness thanks to your mutual support."

"However, don't hesitate to correct him when necessary. You can't be too soft on him."

"Being an Uchiha means facing many trials. I don't want Obito to carry that much either, but sometimes you have to be firm, don't you think?" Kazuki said leisurely.

Kazuki's words sounded strange to Black Zetsu, he even had an illusion. As if Kazuki's words were to accuse him of being immersed in life with Obito and forgetting the important things in his heart...

Black Zetsu suppressed his doubts and chatted with Kazuki, thinking about how to contact Kazuki later.

With simple physical contact, Black Zetsu could use a secret technique to check if there was anything strange about Kazuki.

But after all, Obito was here, and a rash contact with Kazuki might cause misunderstandings...

"It's time to eat, Rin, Kazuki!"

Uchiha Obito was busy serving the sumptuous dishes, wiped off the sweat, and asked Black Zetsu and Kazuki to sit down.

Kazuki smiled and nodded and took a bite.

It wasn't bad at all; Obito's cooking skills were almost similar to those of a professional chef.

Kazuki mused: This could be another example of Obito's amazing potential...

In the Naruto Series he went from an ordinary Uchiha who couldn't fight an Iwagakure chunin, to a strong man who could inherit most of Uchiha Madara's ninjutsu and fight Namikaze Minato, in just under a year.

How could the difficulty of cooking stop Uchiha Obito's love for Black Zetsu?

After eating for a while, Uchiha Obito put down his chopsticks, frowned and said: "Kazuki, there is something I want to ask you…"

Kazuki raised his eyebrows. "Why are you so serious?"

Uchiha Obito smiled embarrassedly. "Since Rin saved me last time, I have always felt that her physical strength seems to be not very good. Every time she does housework, she looks very tired. I am worried that she has not recovered well... Could you check on her?"

Black Zetsu was paralyzed for a moment. It wasn't that he was exhausted; he just wanted Obito to appreciate his efforts! However, on second thought, he saw this as an opportunity to get in touch with Kazuki and check if there was anything off about him.

Black Zetsu had regretted several times not having investigated him when he was healing him, although, at that time, Kazuki did not show any abnormalities.

Black Zetsu sighed. "Kazuki-kun, I occasionally feel headache and weakness..."

Kazuki nodded in understanding, stretched out his fingers very gentlemanly and placed them on Black Zetsu's wrist.

Uchiha Obito looked at this scene worriedly, as if he was afraid that Kazuki would make a bad diagnosis.

Black Zetsu maintained the White Zetsu shell to simulate a normal human body, while secretly sensing Kazuki...

At this moment, although the expression of Uchiha Rin's suit did not change, the eyes of Black Zetsu in the body suddenly widened...

Senju, Uzumaki, Uchiha, Hyuga, at least four kinds of breaths of the mother's direct bloodline descendants!

[From the target Black Zetsu: You have obtained the Mayfly Technique!]

Just as Black Zetsu wanted to continue examining Kazuki, Kazuki had already withdrawn his fingers, turned around and said to Obito with a smile: "Don't worry, Obito, Rin is in good health and has a strong vitality..."

Uchiha Obito breathed a sigh of relief.

As they said goodbye, Kazuki gave Obito and Black Zetsu one last piece of advice.

"Rin, take good care of Obito. With your love supporting him, he can only become stronger."

Uchiha Obito nodded firmly. "Don't worry, Kazuki, I will become stronger and protect Rin!"

Black Zetsu seemed to say goodbye to Kazuki normally, but his heart was already in turmoil.

Kazuki is definitely a very problematic existence!

His body emanated the essence of at least four direct bloodlines of the Otsutsuki, and he even seemed aware of his perception.

What Black Zetsu didn't know was that Kazuki didn't know, but the system notification gave him a rough idea...

For a thousand years, Black Zetsu had used similar methods to identify Indra's successors but had never been detected before.

With this new information, the image of Kazuki in Black Zetsu's mind became even more enigmatic.

Kazuki's words to Obito and to him seemed to have a deep meaning. In retrospect, each one seemed like a message with some kind of guidance, though without malice, and even with a tinge of encouragement.

It was as if Kazuki was checking if everything was going well and if Black Zetsu needed any kind of support…

Black Zetsu pondered a lot but couldn't come to a conclusion about Kazuki's origin.

If there was someone with a higher chakra level than Indra and Asura, who else could it be? But Kazuki's attitude towards him was so strange that if he were related to those two rebellious sons, it would be completely different.

But how can Kazuki have anything to do with his mother?

It's complicated, too complicated!

"Rin, Kazuki is such a good person..." Uchiha Obito said sincerely as he looked at Kazuki's back.

Black Zetsu, with a deep look, replied: "Yes."

After a thousand years of roaming the shinobi world, Black Zetsu had never felt this strange uneasiness.

Kazuki was like an enigma, a mist that made even Black Zetsu, who thought he knew the history of this world, feel the fear of the unknown for the first time.

Instinctively, due to Kazuki's pressure, Black Zetsu squeezed Obito's hand.

Uchiha Obito smiled, put his arm around Black Zetsu's shoulders, and the two of them watched Kazuki's back as he left.

...

A few days later.

"Brother, have you heard?"

Shisui opened the door, ran to Kazuki who was meditating, and said with some worry.

"Kakashi's father is in trouble, and everyone is talking about it now!"
