Ill gotten gains

" Mouse, your target this time is a minor lord from the land of flowers. Eliminate him, and return here with his deeds "

" Mouse you better not fail me again. "

" Congratulation's Mouse. You've made me very proud this time around. "

' My head is swimming with an infinite amount of interaction's I've never had with Danzo. All my thoughts are centered around pleasing him, making him proud, and achieving his dreams. Memories that are clearly not mine are swimming, and then raging through my mind.

Mizu Nakagoshi was Mouse's real name. Orphaned at age 8 from the ninetails attack, he worked his ass off, and passed the academy at an accelerated rate. His talent's were noticed by Danzo, and he was indoctrinated into the Root shortly after graduation. He was used as a tool for assassination as he was an excellent actor capable of deceiving many a lord, and ladies into believing his innocent charade. He was turned from a traumatized kid into a lethal blade.

Mizu was very talented in Shunshin, and kenjutsu specializing in short blades. His low chakra reserves allowed him to fine tune his control, and he had mastered the basics of medical ninjutsu. His smaller frame caused him to shy away from outright confrontal battles, and focus on hiding in the dark.

To summarize from his memories I learned a very small amount of jutsu all the basic D rank jutsu, and d rank fire jutsu as that was his element. He wasn't taught anymore as Danzo cultivated his talents in other areas. Healing Palm, and the chakra scalpel. The body flicker technique. A minor amount of skill in kenjutsu, Knowledge of assassination. A minor boost to chakra, and a small amount of biomass.

It was at this point that I realized the biomass I gained from eating him left me with a few options. I didn't have a system, but a gut feeling like I needed to " spend " the biomass on something. After this event I realized my healing factor, and natural body defense were lacking, and decided to use the biomass improving both.

I could tell the density of my skin would increase by a decent bit, the tiny layer of fat right under the skin had also folded in on itself becoming extremely dense. My red, and white blood cell count had increased by twofold, the improvement wasn't much but it could make a difference. '

Waking up with a fright Haruko looked all around him, and was more than a little horrified now that he was out of the cold logic of his absorbed memories, and evolutionary excitement. Now that he had to see the gore, and really live with the fact that he had just killed Mizu. It was still dark outside, but He could.t tell how much time had passed.

' Fuck i'm going to be sick '

Haruko bent over, and vomited bile. He continued for a short while before coming to a sudden realization.

' That motherfucker Danzo really wasted this kid's life trying to break Naruto's spirit. Fuck I have to clean all this shit. '

Haruko took a moment to look around, and check for potential observers, and found none. Sorting through his memories he found what he needed. Slightly clumsily as it was his first time doing it on his own body he performed the signs for Fire Release: Fire Breath, and a small puff of smoke left his mouth.

' What the shit? Seriously, I still can't do it? Wait a second. '

Red tendrils flowed all around his body before revealing Mizu, or Mouse as he was now called. Once again he performed the signs, much faster this time. " Fire Release: Firebreath! "

A small torrent of fire flowed out from the opened path through his fingers boiling away the blood, and bile left on the grass where he had been impaled. The ground was scorched, and no evidence of their little fight had remained. Hauro then morphed back into himself, and his body shivered once the process had finished.

' So as of this point it only works while my body has been changed to genetically match a natural person from the world of ninjas. However I don't think that will always be the case. '

Now back in his own body he began to experiment with his other Ill gotten gains. An attempt at using the chakra scalpel had merely changed the shape of his hand blade. Instead of being the three foot long short sword it had been it was now a much shorter curved blade. The edge did seem sharper than before however. His attempt at using shunshin resulted in him hitting the side of a building face first, however he could tell it wouldn't be an issue with a bit more practice. Attempting to use the healing palm resulted in the black tendrils growing out from his hand.

' While I'm curious what this will do, I'd rather not hurt myself to find out. '

Notably his control over chakra had increased twofold, the cost for his power's had easily been halved, and the upkeep had been reduced even further.

' Let's check this out properly. '

Activating his sharingan allowed him a better look inside his body, and observe the flow of his chakra. By this point he had already observed many other's chakra color, and the way their system looked. Most had blue, green, or teal colored chakra. A few had more interesting colors like gold, or silver. His however was pitchblack with the faintest trace of red. The first difference he noticed was his chakra was moving at a slower rate, and instead of rampaging through his chakra system it was following along quietly, and controlled. The second was his nervous system of chakra veins had increased slightly in amount. The third was the faint crimson was slightly more pronounced.

' Alright I have no idea how long I've been gone, I should head home for the night. '

Climbing to the roof of a nearby building had been even easier than before. He felt much more confident, and natural in how he was moving his body. Once on top of the roof he began to shunshin his way back home. Quietly opening the door he made his way to his room.

' Holy shit. I just killed, and assimilated that poor kid. Wait fuck that guy he tried to kill me! However he was brainwashed into doing anything, and everything he was told. Fuck do I feel bad for him or not? I don't have the energy to deal with this moral issue at the moment. '

Sweat was beading on his forehead as he sat up in bed, he rushed to the toilet, and then dumped his guts out once again.

' fuck fuck fuck fuck fuck. '

He wiped his mouth, and unleashed another load of bile.

' Danzo is trying to kill me to get to Naruto. He is going to quickly find out Mizu had failed, and will either send somebody better, or go into a full investigation of me. I know he had contact with orochimaru in the show, and he will likely tell him about me thinking I could be an interesting subject for the snake. Oh fuck he could even try to have Orochimaru be the one to kidnap me. How am I going to be able to sleep at night? Don't all members of root have some kind of seal which tells Danzo if they are alive or not? Fuck I can't remember. What am I going to do? Maybe I can convince Kakashi to move in? No, probably not. FUCK! '

As the thoughts raced through his mind Haruko slumped down next to the toilet while massaging his head.

' I just need to finish sorting Mizu's memories, and I'll figure out what Danzo will probably do next. Then I can plan around it. Maybe convince Kakashi to take us on a trip or something? Or reveal something about my power which would make Hiruzen pay more attention to me? I have no idea where to go from here. '

Haruko couldn't ease his anxiety, which led him to the kitchen where he began to chow down on some carrots.

' I can't even properly process the fact that I just killed a young kid right now. Mizu, I never knew you personally but now your memories live on in me. Fuck you for trying to kill me, but I'm sorry this was your fate. My first victim. '
