The world of ninjas and pirates is broken by a demon sword. Uchiha Rin and the Straw Hat boy shoulder the mission and embark on an adventure to protect the two realms.
Uchiha Rin in the ninja world, as a survivor of the Uchiha clan, possesses the dual power of the Mangekyō Sharingan and the Shock Fruit, and accidentally broke into the pirate world due to a rift in time and space. He is good at using the Sharingan to perform illusions and taijutsu. The "Shock Escape" that combines the Shock Fruit and Chakra is amazingly powerful. He constantly breaks through the limits in his adventures and grows from a rebellious ninja to a guardian with a mission. The straw hat boy in the pirate world is suspected to be a descendant of the guardian of the Valley of the End. The six magatama marks on his chest are connected to the origin of the two realms. He fights with his overlord-colored domineering combined with the Grass Pheasant Sword. The flames of the sword and the power of the mark can be combined to release the sealing runes. From being an ignorant pirate to awakening the memory of the guardian, he bravely shouldered the important task of sealing the demon sword and restarting the order of the two worlds.
A mysterious third-generation ghost appeared in the world. Mysterious people and ambitious forces tried to use it to merge the two worlds. The fallen pupil master and other minions caused a bloody storm. The ninja village was engulfed by the flames of war, and the pirate sea was full of dangers. Rin and the straw hat boy met by fate. One was good at controlling the field and the other was strong at defensive seals. The two joined hands to fight against powerful enemies and explore the truth about the split between the two realms during the battle. And a greater challenge is still ahead. Whether they can protect the peace of the two worlds is full of unknowns.
