When Tsunade was very young, her first grandfather (Hashirama) died due to his injuries against Madara Uchiha's fight, at that time Tsunade felt very sad and was crying in the garden. A beautiful 25-year-old girl approached her and consoled her.

The girl from the Senju clan was a friend of Tsunade's mother and was the secretary of the First Hokage, so she was close to Tsunade, who was always with the First Hokage. She was a kind girl who liked to help others.

The girl's name is Saika Senju.

Three years after the death of the First Hokage, Tsunade's mother died four months after giving birth to Nawaki due to illness. Saika takes care of Tsunade and her brother along with Mito Uzumaki. Saika considered Tsunade like her daughter.

After 6 months, Saika prepares to marry the person she loves, but the clan is against marrying the person she loves because he is from the Uchiha clan. Despite the objections of the Senju clan, Saika married.

Tsunade was going every day to visit Saika when she heard that Saika was pregnant. Nine months later, Saika gave birth to a boy, but died in childbirth. Saika's husband took the baby to the Uchiha clan.

After Saika's death, Tsunade began studying medical ninjutsu.

Tsunade used to go to check on Saika's son every month, but did not show herself to him, because the Uchiha clan would not allow her to meet him.

Saika's child was named Ryuu Uchiha.

When Ryuu entered the Ninja Academy, he showed great talent.

When Ryuu turned 7 years old, a young girl named Kushina Uzumaki was welcomed into the Senju clan.

As soon as Kushina joined the Ninja Academy, she formed a relationship with Ryuu, causing turmoil in the Senju clan.

The Senju clan and the Hokage's advisors did not want Kushina to have a relationship with the Uchiha clan, because in the future it would be the jinchūriki of the Kyuubi.

An opponent of Kushina's relationship with Ryuu spoke in front of Tsunade, breaking some of his bones, and Mito Uzumaki was a supporter of Kushina's relationship with Ryuu, because of this, the Senju clan and the Hokage's advisors did not interfere with Kushina's relationship with Ryuu.

Tsunade was angry because they thought Kushina was just a jinchūriki they could use, and didn't care about her feelings.

When Ryuu was 8 years old, Tsunade left the village to perform an assignment. When she returned, Ryuu had graduated from the academy and joined a team.

She wanted Ryuu to team up with her, but she didn't expect Ryuu to graduate so early so she missed the chance of them being on the same team.

She was envious of Jiraiya because he got the student he wanted.

Seven months after Ryuu graduated, his team was assassinated.

Tsunade was angry that her clan had been targeted and sad about the loss of another member of her clan. But she felt a little relieved when she learned that Ryuu was fine.

Then she went to the Third Hokage to ask him to make Ryuu team up with her, so that she could protect him.

A month later, Tsunade was going to the seventh training ground, where she agreed to meet with the Third Hokage and Ryuu.

.....

Ryuu was waiting with Sarutobi Hiorzen at the seventh training ground.

Suddenly a 22-year-old girl appeared in front of Ryuu and the Third Hokage, a light-skinned girl with brown eyes and straight blond hair that fell above her forehead. Her hair had shoulder-length bangs framing her face and the rest reaching down her back. She wore her hair in a ponytail.

The girl was a slender, graceful build with above average height and noticeably large breasts. When Ryuu saw her, he felt his heart beat faster. He had never seen such a beautiful girl in his life. He felt that he had fallen in love with her at first sight.

"Hello, I'm Tsunade Senju. Ryuu Uchiha, I want to accept you as a disciple, do you agree?" Tsunade said, pulling Ryuu out of his thoughts.

'What? Does Tsunade want to accept himsilf as a disciple?' The moment he heard Tsunade's words, Ryuu was a little dumbfounded.

Ryuu is from the Uchiha clan and Tsunade is from the Senju clan. It could be said that the Uchiha clan and the Senju clan, like fire and water, could not get along. He was astonished by Tsunade's desire to accept him as a disciple.

After asking this question, Tsunade was nervous.

Seeing that Ryuu was thinking for a long time, Tsunade was a bit worried, Tsunade subconsciously tapped the ground with her right foot.

With the sound of an explosion, the training ground that was originally intact cracked, a crack spread out in the ground like a spider's web under Tsunade's right foot.

Tsunade was worried that she scared Ryuu and because of that he will reject her.

"I agree"

Tsunade felt relieved when she heard ryuu's approval.

Ryuu had several reasons for agreeing to be Tsunade's disciple. Of course, Tsunade couldn't accidentally intimidate him, which led to his approval. Even if Tsunade attacks him with all her might, he can tackle her with the Mangekyo Sharingan.

If Tsunade really attacks him, the Uchiha clan will take the opportunity to demand benefits and it will cause the Senju clan to get into trouble. So, intimidating Tsunade is not a big threat, but a big chance for the Uchiha clan to gain benefits.

But being a disciple of Tsunade will bring him more benefits, he can learn from Tsunade medical ninjutsu, and he can ask her to teach him more useful jutsu, but his biggest benefit is getting closer to Tsunade.

The news of Tsunade's acceptance of Ryuu as her disciple spread very quickly and within half a day, the news spread to the entire village of Konoha.
