I've just uploaded a new book titled This Hinata Is a Bit Cold! It's a female-oriented fanfiction, so feel free to see if it suits your taste.
Synopsis;
After a lifetime as an assassin, an accident strikes just before his retirement, sending his soul into the world of Naruto, where it merges with Hinata.
On the surface, she still appears weak and timid—but deep inside…
"I endure my family's scorn every single day. I really want to punch them!"
Ps: Like Samsara Tower: Only I Know the Plot!, this story has a large stockpile of chapters. As long as the required Power Stones are met, updates won't slow down.
