Dann wake up with a severe headache and pain all over his body. For an hour he just laying on the beach screaming and rolling to make the pain go away. After sometime the pain gone and he got up and feeling scared since he woke up in an unknown beach with no one in sight not even an animal. He tried to remember anything on his mind but none came to light. He just know that his name was dann and all knowledge about his past life is gone except some random mangas and animes or novels that he read in the past.
He check all over his body and he realize he got small arms and body. He rush to the sea to see the reflection on him self and finally can see that he still has the same body but younger than his original age. His guess is that now he is around 12 years old. After that he laugh like a mad man because based from all the novels he read in the past he basically got reincarnated in unknown world. After sometimes the reality came to him and he got scared since he is alone in unknown world not knowing anything about this new world. He steels him self up and start walking towards the inland since he feels hungry and thirsty. After walking for awhile time he finally find some river in the middle of the island and he start drinking till he got full. He realize the island that he currently staying is not so big around 5x3km. The island is so weird since no animals can be found only some fishes in the river which is weird too since the island is so small how can there is a river on it. Fortunatelly the island is full of trees and plants that have fruits on it so he began eating those fruits to make him self full.
Later he tried to think how to survive on this new world. He looks at the sea hoping to see some boats to rescue him. But the weird thing is the sea is so calm i mean like really really fucking calm since there are no waves whatsoever at the sea. It's like the weather around the island is stop moving no wind no waves and that is so freaking weird.
If he wants to survive at this new world he needs to find a way to escape this weird island.
Later he tried to make shelter near the river using giant leafs and woods that scatter around the island. After sometime he fell asleep on his shelter and pray tomorrow some ships will come to this island and rescue him.
The next morning he woke up and start searching for foods which basically everywhere on the island since the island is full of edible plants and fruits. The good things that happen in this weird island is that no animals including insects can be found in here except a few fishes on the river. So he is basically safe without fearing he will got eaten by wild animals. After eating he tried to explore the island to find anything that can be usefull for his survival.
When he walk around aimlessly he found a weird tree that only got a single fruit on it's branch. The fruit is kinda weird since it looks like a small avocado but with weird swirl pattern around it and the size is like a grape. When he pick it up and eat it he almost threw up all of his breakfast since the taste is so horrible that taste like satan's shit. The moment the fruit got swallowed he feels weird on his body and suddenly he knew a new knowledge about the fruit on his mind. The fruit is a devil fruit named "steal steal no mi" which is a special paramecia devil fruit that make the person who ate the fruit to have abilities to steal. When he realize that he got the abilities to steal on his mind that moment he finally realize that he is now in the onepiece world. He doesn't know where he is on the timeline. He just knew that his new life is so fucked up that strenght is the most important thing in this world.
