Hidden in the Sound
The White Ghost.
He really knew how to make a name for himself. Not that he was trying though, as he was simply keeping unwanted people away from his work. However this White Ghost business seems to be helping keep people away. The rumors and theories that had begun to circulate about him as 'the White Ghost' were certainly intriguing. Some thought he was a shinigami or an angry ghost from the warring states period, others thought he was some sort of demon. People could come up with pretty outlandish ideas, and it was helping him keep people away. Good. The amount of Leaf Ninja he had to force to forget and drag away from his territory was dwindling down. The amount of other shinobi he's had to kill was also dwindling. He was able to work in relative peace and isolation, just like he wanted.
But things change.
His little facility grew into a small community. There were refugees from the recent wars, and he let them stay with him. He didn't regret it. Civilians that wanted protection from the great shinobi nations, there were also missing-nin who wanted to start new lives. These people would need medical treatment and medicines. Tobirama--- Mask was an expert in the fields of science and medical jutsu, he could act as their doctor and use them as willing test subjects. Yes. That is exactly what he would do. And so he did.
T--- Mask performed the more dangerous experiments on himself though. He never subjected these people to dangerous experimental treatments, at least not without permission.... most of the time. He wouldn't do painful experimental treatments on children if he could help it. He wasn't a complete monster, was he? His personal code was complex and had its exceptions and internal rules within rules. Complicated. Mask tried to keep true to science but he had morals, and the reverse was also true, He had morals but he wanted to remain true to science. Confusing. Complicated. Certain people like his elder brother and friend had gotten to him a long time ago and Mask simply accepted that. He was honoring their ideals, he could do that at least... or try to.
Tobirama had newfound freedom now that he was free from the Hidden Leaf. Freedom came with its own share of difficulties and complications though. Was it worth it? Yes. He knew what he was getting into when he planned his freedom, it was all just a matter of adjusting.... and determining his own personal rules. Simple things, that's all.
Such simple things.
Or at least it was supposed to be simple. It was easier for him not to think about it, and that was for the best. The best he could hope for was to be a decent human being and he would at least attempt to be one.
She would want him to be a better person, right?
