The fall of Rome meant the almost total collapse of esoteric and pre-Christian belief systems in Europe, as ancient books and ideas were scattered to the chaos of the Dark Ages. Only fortresslike monasteries, where old libraries could be hidden, protected the mystery traditions from complete destruction. By the time GrecoEgyptian texts and philosophies started to reemerge in the medieval and Renaissance ages, astrology and other divinatory methods began to be referred to under the name "occultism." Occultism describes a tradition — religious, literary, and intellectual — that has existed throughout Western history. The term comes from the Latin occultus, meaning "hidden" or "secret." The word occult entered modern use through the work of Renaissance scholar Heinrich Cornelius Agrippa, who used it to describe magical practices and veiled spiritual philosophies in his three-volume study, De occulta philosophia, in 1533. The Oxford English Dictionary cites the first instance of the word occult twelve years later. Traditionally, occultism deals with the inner aspect of religions: the mystical doorways of realization and secret ways of knowing. Classical occultism regards itself as an initiatory spiritual tradition. Seen from that perspective, the occultist is not necessarily born with unusual abilities, like soothsaying or mind reading, but trains for them. Such parameters, however, are loose: Spiritualism is impossible to separate from occultism. Whether believers consider channeling the dead a learned skill or a passive gift, its crypto-religious nature draws it into the occult framework. Indeed, occultism, at its heart, is religious: Renaissance occultists were particularly enamored of Jewish Kabala, Christian Gnosticism, EgyptoHellenic astrology, EgyptianArab alchemy, and prophetic or divinatory rituals found deep within all the historic faiths, especially within the mystery religions of the Hellenic and Egyptian civilizations. They venerated the ideas of the Hermetica, a collection of late-ancient writings attributed to the mythical GrecoEgyptian sage Hermes Trismegistus. The name Hermes Trismegistus meant "Thrice-Greatest Hermes," a Greek term of veneration for Thoth, Egypt's god of writing, whom the Greeks conflated with their own Hermes (and later with the Roman Mercury). The Hermetica reflected the final stages of the magicoreligious thought of Alexandria and formed a critical link between ancient Egypt and the modern occult.
Zoro questions why Coby is worried since he is not going with them, and Coby replies that it is because they are friends. Zoro points out to Coby that his past with Alvida makes joining the Marines difficult as he has an association with pirates. Coby is left standing there alone, and when the Marines question whether he is with the pirates, Coby claims otherwise. As Luffy is asked if he knows Coby, Luffy goes on about how Coby used to be with Alvida. Angry that Luffy is telling the Marines what he does not want them to know, he hits him. With everyone watching in awe, Luffy begins to punch Coby for hitting him. After the Marines stop Luffy from fighting, Coby is declared not to be with Luffy and Zoro and the two are ordered to leave.
When creating a Devil Fruit, Oda thinks of something that would fulfill a human desire; he added that he does not see why he would draw a Devil Fruit unless the fruit's appearance would entice one to eat it.  The names of many special attacks, as well as other concepts in the manga, consist of a form of punning in which phrases written in kanji are paired with an idiosyncratic reading. The names of Luffy, Sanji, Chopper, Robin, and Franky's techniques are often mixed with other languages, and the names of several of Zoro's sword techniques are designed as jokes; some of them look fearsome when read by sight but sound like kinds of food when read aloud. For example, Zoro's signature move is Onigiri , which is rendered as demon's cut but may also mean rice ball . Eisaku Inoue, the animation director, has said that the creators did not use these kanji readings in the anime since they "might have cut down the laughs by about half".  Nevertheless, Konosuke Uda , the director, said that he believes that the creators "made the anime pretty close to the manga".
