Review Detail of Fito in One Piece: Brothel Emperor

A different story from the usual one piece fic, the mc is not a pirate who creates his crew or joins luffy on his journey, he is simply a prince who creates a brothel and uses the power of the devil fruit to create illusions to satisfy customers while getting stronger by continuous use of his power, it doesn't seem like more than that for now. It still doesn't seem like it's harem or not, the mc doesn't seem to have any interest in it.
