The Joy of Seeing People! The Gentleman Skeleton's True Identity!

On board the Thousand Sunny, with everyone save Luffy unnerved by his appearance as an undead creature, Brook reveals that he is actually a human with Devil Fruit powers. Brook explains that he was a pirate musician before being killed alongside his shipmates when they were attacked. Though the Revive-Revive fruit he ate prior brought him back to life, it took his disembodied soul a year to find his body which has decayed within that period of time. When everyone noticed Brook's lack of a reflection, the skeleton reveals that his shadow stolen and cannot enter sunlight without being destroyed. For that reason, admitting his joy to be around others after a very long time of solitude, Brook turns down Luffy's offer to both join his crew and offers to play for the Straw Hats while he is able to enjoy their company. But a ghost suddenly appears in the galley, and the Straw Hats find out from a frightened Brook that the barrel they found prior was a trap as they find themselves targeted and on the ghost isle Thriller Bark.
