Paradise

Before we left the restaurant, Zeff said me there're people who named the Grand Line as 'Paradise'! Shishishi

The Paradise (楽園（パラダイス）) is the name of the first half of the Grand Line. The name was coined by the men who ventured in the New World, compared to which "the first half is a paradise".

Navigation
The first half of the Grand Line, the Paradise, is located between the East Blue and the South Blue and is accessible from all the Blue Seas thanks to the Reverse Mountain who links them. From the Twin Cape, the sailors can choose one of the seven routes to follow in order to reach Fishman Island and then the New World.

The Paradise is full of strange weather phenomenas that make the navigation very hard.
