1 Teleported to Another World

"Mommy! There's a scary masked man on the ground in front our house!!" a little girl said while yelling for her mom.

"Don't be silly how could there be a person in front of our house? You must be imagining things." the mom replied.

"No no! Look, come on hurry!" The girl said while pushing her mother outside.

"Haa... What am I going to do with -" as the mom was about to scold her daughter she looked up and indeed saw a masked man wearing a weird robe with red clouds lying on the ground in front of her house. Further more he had a item which looked like a fan in his hand furthering his mysterious appearance.

As the mother was about to approach the masked man in order to see if he was alive or not, he suddenly opened his eyes. One eye was bloodshot red with three tomoe and the other eye was light purple with black lines circling inside of it.

Seeing such bizarre eyes the woman took multiple steps back in fear. "W-who are you?" she asked while keeping her daughter behind her.

The man gazed at her for a quick moment before saying "I mean no harm. Go back into your house I will take care of myself."

Seeing that the man meant no harm, she suddenly relaxed and did what the man in front of her told her to do and went inside the house. "What a mysterious man." she thought pondering over the man.

"System what happened? I thought I was fighting against Kaguya Otsutsuki?" the man asked.

System: After defeating Kaguya Otsutsuki, your life force was completely depleted when using Samsara of Heavenly Life to revive all the lives lost during the fight excluding the enemies. In exchange of reviving you used your mystery box which was using tears of denial and you have teleported to the One Piece Universe to start a new adventure. If you would like to return to the Narutoverse you must be strong enough to break through the dimensional gap separating the two universes.

[Tears of Denial is a game reference...]

This man's name was Zen, the man who saved the world of Naruto after reincarnating as a orphan in konohagakure and creating the Akatsuki who saved the world from total annihilation after supposedly dying at the age of 16.

[Clearly canon]

"Ah right.. Okay so what universe am I in now?" Zen asked.

System: Currently you are in the One Piece Universe.

"Huh One Piece? Another anime related universe?"

System: Of course! The system will transport you to every known anime universe as long as you will it and have enough points! Since tears of denial was a mystery gift given to you when you reincarnated, you would have never transported and just died at that spot. Tears of denial cost 100,000,000 million points!

"Good, my stats haven't changed to much. System, what is my objective in this world?" Zen asked

System: Unlike the narutoverse where you had to save the world, your goal in this world is to become the pirate king and gain a harem! Unable to do so will strip you of your dojutsu.

"A ninja becoming a pirate king? Are you serious?" Zen thought to himself.

"Wait? A harem?"

Honestly if I make any novel expect it to be a harem.
