The night before his 4th birthday Eric was super excited making it hard for him to sleep. Finally after a hour of staring at the ceiling Eric fell asleep.
Eric: "I hate the sun."
As the sun shines on Eric he puts his hand in the way to block the lift and notices a sliver ring with a dark blue gem in it on his finger.
Eric: "Finally. I have wasted far too much time."
Eric closed house eyes and could see Gae Bolg, a dark blue and sliver suit, a weird looking fruit, and three manuals. Eric grabbed the fruit and took a huge bite. Instantly regretting his decision Eric almost throws up but doesn't.
Eric: "Jesus Christ that was the worst the I have ever had."
Then he took the observation haki manual and opened his eyes. Back in the real world he started to study the manual getting a sense of how to train it he puts it back in the ring and walks outside.
Eric walks to a dango shop which is his favorite place in the village. After eating his fill of dango he starts to go to the forest but is ran into by a blonde kid with whiskers about his age. This is of course Naruto.
Naruto: "Hey watch where your going. Wait I think I know you."
Eric: "You don't."
Erica starts to walk away but Naruto follows him and starts rambling.
Naruto: "I'm the greatest prankster ever. You see the blue paint on the hokage faces that was me hehe." Seemingly proud that he disrespected the previous hokage
Eric: "Don't care. Leave me alone." he is starting to get angry.
Naruto: "Hey is that anyway to talk to the next Hokage."
Eric: "What are you on about?" Eric asked already know the answer
Naruto: "When I grow up I'm gonna be the Hokage. Believe it." Naruto yelled
'I should get away from this guy before my reputation drops.' Eric thought
Eric: "Is that so, so how come the next hokage didn't see the ramen shop we just passed."
Naruto: "What ramen where I don't smell it. Where did you say it was."
When Naruto turned around he realized he was alone.He vowed to prank the blue haired kid.
Jumping from building to building Eric makes his way to the forest and starts to practice his devil fruit.
Eric: "Dammit! Why won't it work?!" Eric was getting angry but calmed down.
He was trying to do doflamingo's spider web.
But couldn't and he realized that he had to start from the basics. So he started off practicing producing string for a week then he practiced moving them around and getting used to it for a month.
After that he decided to work on he observation haki by blindfolding himself and fought animals in the forest. He went 2 months without taking off the blindfold and made great progress. He could sense things 10 meters around him and could now use the strings as attacks though they weren't deadly attacks it would due for now.
He kept at his training for 3 more months and decided to get weights added to his training gear.
Eric was walking down the street in ripped up clothes from all the beast fighting. Almost everyone he passed gave him strange looks but to him they were trash. Making it to Tenten's dads shop Eric asks for 4 50lbs weights and 2 100lbs weights.
Tenten's dad was about to cough up blood 'this brat wants to buy what'.
Papa Tenten: "Hey kid how old are you"
Eric: "4 and a half."
Papa tenten almost had a heart attack.'This was a four year old kid asking for those kind of weights.'He looks at Eric again 'There is no way that boy is 4 he has to be at least 9 yeah that's it he was lying it has to be.'
In his defense Eric didn't look anything like a 4 year old he was 4'11 well built with short spiky blue hair and a ponytail that reached his back. The ripped up clothes shows he has been in countless fights and his dark crimson eyes are radiating bloodlust and death.
Eventually Eric got his weights and went back to the mountain to train but before he went to train he dug up and grabbed the hidden money as he just ran out of funds.
After applying the weights to his new training outfit which he also got from Papa tenten he began to train. After training he went home took off his training gear showered went to his bed room and got in bed as he was thinking about upping his training he heard a thunk and activated his observation haki and saw someone in his living room.
