In Naruto's journey from an outcast to the village Hokage, he's met a bunch of people. Some challenged him, some wanted to hurt him, and some only cared about him. Tsunade is one of those people who makes a strong bond with Naruto.
She truly cares about him and when the need arises she does everything in her power to protect him. Despite being an important character, not much is revealed about her past. The only bits of information out there is fan's speculation, that lacks solid proof.
10 Who Are Her Parents?
This one thing is never revealed about all the three legendary Sanin- Jiraiya, Orochimaru, and Tsunade. Their parents died too early and did not contribute anything to the main story. Therefore, they are left out.
In the case of Tsunade, her father was Hanaku Senju, the son of the First Hokage. Fans never got their glimpse or what they were like. It is a mystery to this day.
9 Why She Is Afraid Of Blood?
Tsunade's phobia of blood can be justified considering she was unable to save her lover, Dan. Her healing abilities fell short when it mattered the most. From that moment on, she could not stand the sight of blood. This is not suited for a Hokage and a shinobi.
She had to fight on the frontlines of the war. Patching up warriors who are injured and tacky with blood is her job. It restricts her to perform at her 100%.
8 Her Actual Age Right Now
Despite seeing two generations of Hokage (Kakashi, and Naruto) grow up, Tsunade looks the same as day one, in her twenties. Her actual age was claimed to be around 50. Tsunade uses her reserve seal to keep herself young but its effect wore off when she had to spend all her chakra on healing herself in the war.
Here's the catch, for every injury Tsunade heals with her Creation Rebirth Technique, her lifespan shortens. Meaning her body is older than the time she has been alive. But it is never revealed how much of her age has been shortened.
7 Where Is She Right Now?
Tsunade played a major role in Naruto and Naruto Shippuden. She was the Hokage of the village and acted as an aunt for Naruto. Contradictorily, in the latest entry in the Naruto series, Boruto, she is nowhere to be found. She appears once or twice in Boruto and Naruto: The Last Movie.
Unlike Kakashi, who actively takes part in the village's decision. Tsunade seems to be on a vacation. But where did she go? She could be a valuable asset to the village and can still perform her duties.
6 Her Relation To Naruto
Mito Uzumaki was the wife of the First Hokage, Hashirama Senju, who is the grandfather of Tsunade. Naruto's mother, Kushina, was also an Uzumaki and might have had some relation to Mito Uzumaki.
It is known for a fact, that Naruto is a distant relative of Tsunade. Unfortunately, that side was never explored and fans have speculated some possible ties. But the final say is of Masashi Kishimoto, who is yet to say anything about it.
5 Is There A Slug Sage Mode?
Sage Mode is the absorbing of chakra from nature and using it in battle. Naruto, Jiraiya, Hashirama, and many other powerful shinobi can tap into Sage Mode. It grants a sudden boost in power. Therefore, it was disappointing to see Tsunade being excluded from it.
Katsuyu lives in Shikkotsu Forest, a sage region, meaning Tsunade actually can use Sage Mode. Since it is a time consuming and dangerous process, they may not be willing to learn it. She can become insanely strong is she does learn it.
4 How Did She Train Herself?
Jiraiya and Orochimaru followed in the footsteps of the previous shinobis and used their techniques to become powerful. But there is no explanation or insight into Tsunade's journey at becoming the best medical ninja.
Her abilities are unmatched, and Sakura is the only person ever to match her level. It is a big plothole and needs to be explored further.
3 Why is She Closer To Naruto And Not Sakura?
Fans may have noticed the interactions between Tsunade and Sakura being formal with both respecting each other. While Naruto is always cozy with her, challenging her to a fight and calling her old. Naruto does not forgive anyone.
Jiraiya acts as a fatherly figure for Naruto. The same level of affection should exist between Tsunade and Sakura as well since they have been through hell together, but it doesn't.
2 Why Was She So Weak Against Kabuto
In her fight against Madara, she was able to damage his Susanoo, to which Madara himself compliments her strength. She was called a legendary Sanin in the war. So a mere lackey like Kabuto should not give her a hard time. Except he brought her to her knees.
She was only saved because Naruto intervened. There were thousands of ways she could've stopped Kabuto's advance instead she'd let herself be mauled by a low-level criminal.
1 Why Did She Suppress Her Feelings For Jiraiya
Jiraiya had a thing for Tsunade from the start. He used to compliment her physique and put forward his feelings many times. Even though, her first love was Dan, to which Jiraiya happily approved. After being alone for so long, something changed in Tsunade. Before Jiraiya departed the village, he talked with her.
He asked if she would give him a chance once he comes back and she agrees. But things did not go as planned. If only she would've expressed her feeling earlier then things would be a lot different. Tsunade messed up horribly.
