Yomi Yomi no Mi

The Yomi Yomi no Mi is a Paramecia type Devil Fruit which allows the user to come back to life after being killed. Initially, this Devil Fruit has no effect except for the usual side-effects such as not being able to swim. When the user dies, however, it brings them back to life once. Upon death the spirit is halted from traveling to the realms of the dead and is instead allowed to locate its body and be revived. However, this does not prevent the users body from decaying, hence Brook's skeleton appearance. The term, "yomi", could have one of two meanings, and both are implied in Brook's explanation of the fruit. It could be short for "yomigaeru" (蘇る, "revive" or "reborn"), or it could come from "yomi no kuni" (黄泉の国, "realm of the dead" or "the underworld"). In the Viz Manga, it is called the Revive-Revive Fruit. It was eaten by Brook.

Strengths and Weaknesses


The major, if not only, strength of the fruit, as demonstrated by Brook, is that it just gives its user another life after being killed. After death, the user continues to exist in whatever state they were revived as and can even go as far as to grant a form of "immortality" that lasts until the user suffers a second death. However, since the main power of the fruit is resurrection, the Yomi Yomi no Mi's power will remain dormant until the time when the consumer suffers his or her first death. As a result, until such time, the only aspects the fruit bestows upon its eater are the typical Devil Fruit weaknesses. Furthermore, while the Fruit allows the user's spirit to once again return from the afterlife, it does not automatically return them to the physical body that it once resided upon during its mortal life. Thus, it is then up for the disembodied soul to search for the corporeal body in order to once again reunite with it. Though the user gains another life, their body however will continue being a lifeless corpse and will continue rotting away until the user's soul can find its way back to the body. When the user's soul returns to their body, the powers of the Devil Fruit will fortunately support the user's well being in the case that their body may be in a condition unable to support life.

While the fruit can make the user an undead being of sorts, it however grants the user the ability to still feel pain as proof that they have been truly resurrected back to life, regardless of what physical condition they've been revived in. Other than that, the user is affected also by standard Devil Fruit weaknesses.

Usage
While the fruit's only major bestowed power is only usable after death, it's secondary powers however are rather useful in keeping Brook basically "alive." Through the fruit's powers, Brook is able to function without the presence of necessary and vital body parts that have decomposed long ago. He is able to move and stand up without the presence of tissue and muscles to support him, as well as be capable of getting tired or worn down despite not having any of those factors to begin with. He is able to interact with the environment around him without the presence of eye balls or any other sensory organ to aid him. He, in particular, retains his ability of speech despite his vocal chords and even his windpipe have long since rotted away. He is able to taste and digest food like any other normal living thing to sustain himself. Drinking milk in particular heals him as the calcium intake repairs any of Brook's bones that may have been broken in battle. Depending on the situation, Brook is also able to produce organic matter such as tears, fecal matter, and even blood from his nose despite not having any organs nor bodily liquids to produce such matter.

Due to the fruit's powers holding up and moving his light skeletal frame, Brook is given an extremely light body. He is able to perform seemingly superhuman feats such as jumping extremely high and running on water. These allow him to travel great distances and aid him in battle. However while his light body lets him be lighter than an average person, Brook isn't immune from sinking. Brook will still sink like any other Devil Fruit user when placed in water. In fact, while Brook can run on water, he cannot stay above it too long.

Being a skeleton animated by the fruit's powers also allows Brook to do things that most other people cannot do due to their need of tangible living tissue. Not only is he able to use his light weight to execute fast attacks, but his lack of flesh also allows him to execute attacks that would otherwise be harmful, such as shocking himself with electricity and becoming an electrically charged projectile. Due to the lack of organs, Brook is also able withstand some deadly attacks to a certain degree. For instance, he was able to withstand his skull being shattered to a certain degree and was also able to withstand having several of his ribs broken. Also, due to the Devil Fruit powers allowing it, Brook also has the ability to store objects in his skull by opening it along its crack. While Brook is able to do these things because of his Devil Fruit supported form, he however can still feel pain, as well as fatigue. Based on his own statements and comments from others, despite the lack of any muscles it appears that he is able to grow stronger through normal training. Though Brook is able to repair broken bones, it seems all growth functions have stopped. For this reason Brook puts alot of effort into protecting his afro, since he would be unable to grow it again if it was cut.

Trivia

 * Brook's soul, upon returning to the mortal realm to search for his body, resembles a hitodama, a representation of the recently deceased commonly found in Japanese folklore and pop culture.
