Vida

A Vida is a vampiric plant used to extend the shelf life of a meat which functions by absorbing the blood. It made its debut in Chapter 1 of The Promised Neverland Manga and Episode 1 of the anime.

Introduction Arc
A Vida was first seen on Conny's chest, as it has already absorbed her blood and took her life away. The pale appearance it has left on Conny's face frightened Emma and Norman, who were searching for her at that time.undefinedundefined

During one night, Norman has a nightmare during his sleep, he dreamt of seeing all of his beloved siblings lying dead on a puddle of water, each with a Vida impaled into the chest. Norman ran to Emma and sought to wake her up, only to be confronted by a large demon which attacks him from on top. Norman soon woke up from his nightmare, flabbergasted.Manga citation neededundefined

Jailbreak Arc
A demon lurked out of the shadows and approached Krone, as it grabbed the latter and stabbed her with a Vida under Grandmother's orders. As the Vida slowly sucked her life away, it turned blood red in color as it blossomed, leaving a pale-looking, deceased Krone underneath it.undefinedundefined

Appearance
The flower has a similar appearance to an ordinary flower. It has a sharp stem, with several branches that give rise to several leaves. The petals are initially white in color and closed, and would bloom and become blood red in color after absorbing the blood of its victim.undefined

Usage
The Vida can only suck the blood of its victim if it is stabbed into his body and in contact with his blood, which is most likely the reason why the roots are cut off and left with the stem, which makes it easier for it to impale the victim and absorb the blood. After it absorbed the victim's blood, the victim will die and turn pale in appearance.
