Seth started his scythe training the manual book of the scythe wielding has 5 stages. beginner,intermediate,advance,expert and master level. To break through the beginner stage seth must first do body training because if he doesn't have a strong body he can't wield the scythe properly.
In the manual there was a training regime for a strong body it was called "Saitama Training" 100 push ups, 100 sit ups, 100 squats and 10km run everyday! seth was shocked "Is this really serious?! don't tell I'll also go bald like saitama." seth then started his "Saitama Training"
1 month passed seth was now doing triple of the "Saitama Training" he was doing 300 push ups, 300 sit ups, 300 squats and 30 km run everyday. he then took out the scythe manual he must swing the scythe for 1000 times everyday for 1 month and to comprehend what the book says.
Another month passed while seth was comprehending the book when he felt his body burst with energy "Did I just broke through the beginner stage?!" seth was in a state of disbelief he then proceeded with his training.
To break through intermediate stage he must have actual combat, seth was thinking who would he have as training partner then it hit him "There's a dense forest on the south of peanut island the villagers from brittle village told me that there are strong beasts residing there" seth immediately dashed towards the south forest to train with the beasts there.
2 months passed and seth could be seen eating with a white tiger beside him resting he finally broke through the intermediate stage and was eating with his new buddy "Whitey"
He wanted to break through the advanced stage but in order to reach the advance level he must first learn how to use haki, so his next training would be about his haki which he had no idea how to awaken it, but luckily for him the book has it all including haki training.
Seth first started with his observation haki he covered his eyes with a cloth then told whitey to attack him everywhere, the first couple of days of training seth had cuts everywhere because whitey didn't hold back while training.
After training for a month or so seth broke through the beginner stage of observation haki. he then proceeded with his armament haki, which was tricky the book told him to keep on fighting while thinking that his arms were clad with armament haki.
Seth did as the book told him and eventually after 2 weeks of fighting he can now use armament haki for couple of seconds, he continued with his training and after 1 month he broke through beginner stage
A/N: I will put stages on haki so that we would know his improvement level. the stages are split into beginner,intermediate,advance,expert and master. we will make it like the scythe manual to make it easy to understand.")
The next was his conqueror's haki but the book told him that he only need's to have a strong will to unlock it, and told him that he could try fighting multiple beasts and maybe his conqueror's haki will awaken.
9 months passed by and seth finally reached the advanced stage of conqueror's haki, while he reached the expert stage of observation and armament haki. "well I think im finished with my training here. and there is still 6 months before the story starts and maybe another 3-5 months before luffy and others reach the grandline." seth was thinking if he would create a crew or just join luffy's crew he didn't even give a fck if the story changes because of him he just wanted to enjoy his new life. fck the plot fck the butterfly effect cursed seth.
After thinking on what to do next seth finally remembered that he didnt have any devil fruit. "what kind of devil fruit would I find logia type would be a good choice maybe wind logia fruit but where would I even find that." after thinking he gave up and just let fate decide on what kind of devil fruit he would encounter.
After deciding to leave it to fate seth went to brittle village again in order eat then ask where the port was.
he went to the port and surprisingly he saw a pirate ship docked at the port. he went closer to the ship they had 20-30 crew members their captain has a bounty of 40,000,000 beli but seth didn't even flinch to him the training he did was enough to fight a admiral what is measly pirate with a 40M beli bounty to him?
He went to crew member and asked him where his captain is. the crew member got angry started cursing at started creating a commotion. suddenly a bearded man came to seth sides and tap his shoulder saying " whatcha looking for me mate?" I looked at him and told him " so you're the captain from now on you will listen to me I don't have a ship and want to sail to find some suitable devil fruits.
As seth finished his sentence all of them laughed at him.
"HAHAHAHAHAHAHAH is this guy crazy?"
"I think he is, maybe he needs some wine to think properly"
"finds suitable devil fruits? who does he think he is devil fruits aren't cabbages HAHAHAHAHA"
" Mate are you kidding me? why would I even listen to you?! we are pirates and you're just asking us to be your tour guide? HAHAHAHA what a joke!" the captain mocked him.
"oh? so you don't want to help me?" after that he released his conqueror's haki knocking out every single crew member except the captain. When the captain saw his members fainted he pissed his pants of and kneeled unconsciously he pointed looked at seth with pleading eyes then saying " we will help you boss. please have mercy and don't kill us we were wrong.
With that Seth withdrew his aura and told the captain to wake his crew members. when they woked up the captain told them what happened and when they looked at seth again it was filled with awe,respect and FEAR!
"Okay now that all of you are awake tell me if you have any clues you can find about some obtaining a devil fruit" Seth ordered. immediately the captain told him that he heard that there was a black market on the neighboring and it organized by man name joker and they are selling many kinds of devil fruits there.
"ohhh? joker? Hahahahaha lets go to that island let's see if I can the devil fruit I want." with that seth and pirate crew seth to the neighboring island.
