Naruto pov
Darkness that is what i felt when i gained this power hatred is what i felt envy is what i felt and something more evil i tried to figure out who it was coming from only to find out it was me but that was impossible i would know if i was evil or planning something evil then i began to think it was just a prank so I rubbed it off some time later i still felt it it never vanished one day i woke up and i looked in the mirror to see my left eye was black completely black while my right eye was my normal blue my eyes blinked and once they opened again my left eye was back to normal something was happening to me i-i was changing not the normal kind of changing no i was becoming something..what the villagers were calling monsters demons anything related i was becoming true evil a real demon a real monster a few days later i was doing my normal duties as Hokage when something black bleed out of my thumb while i was doing paperwork and manifested itself into a tiny demon it was black with a tail wings and pointy ears it looked at me then it opened it's mouth which had sharp black fangs it began to speak i was surprised it could talk it called me master i asked it what it was it told me it was a part of me a manifestation of me I asked how it told me the moment me and Kurama accepted each other a power was born in me I asked myself out loud what had i become and in my surprise the little demon answered my question that i am the dark lord i told him I'm not the devil but it didn't say the devil it said "i clearly said that your the dark lord meaning your the king of darkness not the underworld the god of darkness you control all that is dark or mixed in with the dark" i was speechless me a god that controlled all that is dark it spoke again "a newborn god is what you are one that can create untold evil like me I may be small but don't let my size fool you i am as evil as i am powerful i only serve one master which is you my creator the only one who commands me and my brothers and sisters" soon after i called in my Anbu the team leader was Sasuke Uchiha my best friend lead by his wife Sakura Uchiha then Shikamaru Nara and finale Choji Akimichi they all looked at the tiny demon and before you knew it they were in a battle stance i told them to stop "lord Hokage what is this thing?" asked Sasuke
"this..is my son," I said they all looked at me in shock
"what?" asked Shikamaru with eyes widened like the rest
"my lord I am not your son I am your humble servant," said the tiny demon the team looked at the demon than to me
"hokage-sama is this true?" asked Sasuke questionly
"well kind of but not in the way you think" Naruto stopped for a minute "Andrew is the name I will give you," Naruto said looking at the little demon "Andrew-san may you please explain what you are to my friends?" Naruto asked Andrew just nodded his head while it was going on about what it was to the others Naruto was thinking about what had happened today he had created a demon he found out he can control darkness "I will need to learn how to use this power otherwise it will go out of control I'll have to ask Andrew to teach me" Naruto thought to himself
"and thats what my lord is" Anderw finshed
"thank you anderw-san" thanked Sasuke
"if I may ask does my lord have a lover?" Anderw asked looking at the one he calls the god of darkness
"no he's never had one,I," said Sakura
"and how old is he?" asked Andrew
"wow that's some personal questions but if I had to say 17" Choji answered Andrew nodded
"thank you one last question does my master have any children," Andrew asked
"no he's never been in a relationship of any kind though once he was offered by one Hinata Hyuuga but he declined" Sasuke answered for the little demon
"i am truly sorry but this leads to another question," Andrew said
"we will Anderw if you answer ours do we have a deal?" Sasuke asked
"yes i believe we do," Andrew said "please tell me what you wish to know" he finished
"do you wish to harm Naruto-sama in anyway and if he cammands it will you do it?" Shikamaru asked
"there are three rules I must follow Shikamaru-san" the demon said raising his hand showing three fingers "rule one i must obey my master as do my instincts say rule two i must protect my master at any cost and finale rule three if my master wishes it i must abandon rule two and end his life or let him die" Andrew answered
"if Naruto-sama wishs to set you free what will happen?" Sasuke asked
"i will simply become human and do as i please but starting from child to mature," Andrew said
"can Naruto-sama lose control and if so what would happen?" Sakura asked
"he will unleash untold evil upon this world the likes of which you've never seen," the demon said the Anbu team's eyes widened looking at Naruto "but that will only happen if the lord of darkness finds a way to seal his power
"will they be like you?" Shikamaru asked
"no they will be stronger than me, not even my master would be able to stop them there the only wish would be to fully reconnect with him though they will still have some kind of connection and they will do anything to get what they want which is my master," the demon said
"why do you care if Naruto-sama has a lover or not?" Sakura asked
"if my master mates with a female or male they will gain similar powers but not the same now this does not account for his previous or first lover they may gain his power through sex again now this stands for anyone he mates with or anything," said Andrew
"how can males gain his power?," Sasuke asked
"my master can change gender if he wishes so" Anderw answered
"are your kind the only ones that can kill Naruto-same," Shikamaru asked
"yes even though he's immortal he still has a weakness as does everything," said Andrew "is there anymore?" Anderw asked
"no you may ask your question," Shikamaru said
"why did my lord decline Hinata Hyuuga's offer?" asked the little demon
"Naruto-sama did not feel a connection to Hinata-chan and Kiba-kun had a crush on her so he declined" Sakura finshed
"thank you Sakura Uchiha," Andrew said while they were talking Naruto was listening to every last bit
/presant/
everyone was on a ship heading north
"so Naruto-Kun where is the dark castle?" asked Sirzechs satan of the underworld to the driver of the ship everyone looking at Naruto Naruto set the ship on autopilot and turned to look at everyone with a serious face
"on a hidden island I've put a illusion on it if people go near it all they see is a waterfall when we get there i will uncloak it," Naruto said walking to his dorm
"he's serious" Sirzechs said seriouly "things are never good when he's serious"
