One plot idea could be that baby Naruto somehow gets lost in the village and Tsunade finds him. She then decides to take care of him for a while, teaching him some basic ninja skills in a very gentle and motherly way. Another could be a time - travel scenario where Tsunade meets baby Naruto from the past and has to protect him from a new, unknown threat. And a third idea is that there's a strange illness in the village that only affects babies, and Tsunade is determined to cure Naruto using all her medical knowledge and skills.

One idea could be that Naruto discovers a hidden jutsu that was once known only to Tsunade's family. This jutsu could be related to healing on a massive scale, like being able to heal an entire village at once. Naruto, being the curious and kind - hearted ninja he is, wants to learn it to help more people.

There, they have to rely on each other's skills, Naruto's combat abilities and Tsunade's medical and strategic knowledge, to find a way back home.
A plot could involve young Tsunade being in a difficult situation where she loses confidence in her abilities.

Perhaps Naruto gets injured severely during a battle and Tsunade has to use all her medical skills to save him.
