I do not own Naruto and/or One piece. If you haven't seen/read either, then do so before reading this, 'cause I'm not going into too much detail for either. Flamers will be used to make smores.
Story needs
I don't know how Naruto ends; I would prefer cliff notes, Please PM me. A Beta would helpful.
Stories Idea
after the war, Ninjas are too few and not need anymore, and somehow Naruto learns about a stone that can transfer and hold very old knowledge in Uzu no kuni. When he gets there, he learns of a Sea Gate that connects to the one piece world, which was closed before the Sage of Six Paths mother was born.
Said stone holds a copy of the plans for Pluton, but the Nations don't have all the resources to build it exactly, so Naruto used the stones store of Fuinjutsu and ship building to rewrite his own copy to compliment its use by Chakra users. Ship is big enough to fit three Juubi's inside it with room to swing their tails, or the remains of the shinobi forces as a hidden village, and all that entails. Such as Private quarters, Blacksmiths, Hospitals, training spaces, an Academy, officer quarters workshops for trade goods and shininobi studies and the like. I rip the Pluton Idea from Overlord of the Seas, for size at least, but I want it to join fuinjutsu in its construction and defences.
Cannons will be replaced with normal 28-pounders (5 rows with at least 20 per row), Mortars may have exploding tags (16 Total around edges of sip). 6 swivel guns with Element seals carved in on the outsides and insides, so that it will fire small rounds of selective jutsus. (wind bullets, water jets, Flamethrower, maybe a Small lava bomb.) Defenses would include chakra metal inscribed with seals for reinforcement, strengthening and (maybe) Barriers, and a Genjustus that hides the ship. (Thou a Hidden Mist jutsu might be added for theatrics [one of a ninja's best tool].)
Cargo holds can be replaced with racks for storage scrolls of varying sizes, same for foodstuffs. Cabins will account for unknown mix of genders, or families. Sails will have Wind Seals inscribed on them to increase speed with less sails. (Maybe a water jet pumps system for secondary propulsion, like steering or something.)
Additional Ideas for the ship will be read.
Thou he has brought peace to his world, the need for conflict still haunts the remaining ninja, and the Sea Gates offer a outlet for this as well as a Vacation of sorts for others.
Ideas of where it goes from there will be looked at, then judged, the best in my opinion will be taken.
Kindly review, feedback may decide how the story goes.
