Yomi Yomi no Mi

The Yomi Yomi no Mi is a Paramecia-type Devil Fruit, eaten by Brook.

Initially, this Devil Fruit has no effect except for the usual side-effects(i.e., not being able to swim). When the user dies, however, it brings them back to life once. Upon death the spirit is haulted 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").
