Tobirama found you as a small child because he arrived too late. Your parents, the guardians of the ancient writings, were killed, but he managed to return the stolen writings. You are left alone. He couldn't help but blame himself. From then on he took you under his wing.

When you grew up you became a very strong Shinobi, although...the time of the first World Shinobi War was already starting. Times were getting worse. And life was starting to be increasingly uncertain.

You loved Tobirama like your own father because you didn't even remember your past. Tobirama used to be rude sometimes, but you knew he wanted the best.

Tobirama was in his office thinking about plans and consequences...he couldn't seem to get a break lately.
