Summary
Kai was completely out of his depth in this. Surely Pops had to have known this right? He wasn't built for this, children were too confusing and he was not the right person to be taking care of a traumatised three year old.
Life is funny how it turns out though and healing is usually easier with someone by your side.or How Chisaki Kai warmed up to Eri

Summary
Eri was a happy, normal enough child so when she was quiet Kai tended to become suspicious. He did enjoy the quiet but knew that if he didn’t nip this in the bud it could get catastrophic and lead to having to deal with a moody 4 year old for a possible week (surprisingly she could hold a grudge if she really wanted to, it would be impressive if it wasn’t him that had to deal with the outcomes).

Summary
“Oi, Tomioka—”
“Which one?” Shinobu asks with a close-eyed smile.
He hesitates before pointing to Giyuu. “The original one.”
Giyuu blinks, pointing to himself, while Shinobu folds her arms across her chest. “My, I don’t quite like the sound of that. It makes me feel like a counterfeit.”
Giyuu and Shinobu—married, a little annoyed (but happily), and learning how to share everything... even their name.

Summary
Shinobu always felt like she was short on time.
Time was running past her, demons were getting stronger, and more people were suffering and dying. So she had no choice but to pick up the pace. She had to pierce her enemies swiftly before they could kill her. She had to analyze poisons quicker than they could deteriorate and kill. She had to train her Tsugukos harder so they would have more time. It’s why she spent a year injecting herself with wisteria. To become the ultimate weapon against the demon that killed her sister, she would gladly sacrifice her time.
And yet, in her last moments, as she felt coldness seep into her skin, her lungs, every vessel of blood in her veins, she wished she had more time.
An AU where Shinobu gets more time.

Summary
Team 7 didn't make it in their fight against Kaguya in different dimensions. So the Sage of Six Paths grants reanimated Hokage a chance of fixing it all before it started, but only one can go. They chose Tobirama Senju because he knows Uchiha better than anyone else and has the best chakra control over all of them.
When he woke up in his 9 year old body next to his long dead twin, Tobirama swore he'd prevent Kaguya from coming back. And for that he must watch Madara closely in order to catch Black Zetsu and deal with the source of the disaster himself.
And what's the best way to closely watch someone from their enemy clan if not marrying them?
or
Time travel Tobirama AU, where Tobirama decides to marry Madara to prevent The Fourth Shinobi war.
