About Soru Soru no Mi
The Soru Soru no Mi is a Paramecia-type Devil Fruit that allows the user to interact with and manipulate souls. It was formerly eaten by Carmel, but the ability was somehow transferred to Charlotte Linlin after Carmel's death.
The fruit's power of soul manipulation, as demonstrated by Big Mom, consists of manifesting and drawing out the souls of people who feel fear towards the user. The manifested souls take the form of a light-pink, spectral-looking but (for the user) tangible substance, which leaks out of the victim's body like smoke. The user can extract the victim's soul by grabbing it once it is surrounding the target's body and pulling it out. This effectively steals from the victim's very lifespan, the amount of which is determined by the user: it is possible to steal decades of a person's life at once should they desire, or mere seconds. The user can steal part of the victim's lifespan, leaving their remaining lifespan that much shorter, or even take enough years to steal a victim's entire remaining lifespan, killing them instantly.
By infusing objects with soul fragments, the user can "humanize" them. Recipients (which are referred to as "homies") gain human-like intelligence, as well as the ability to speak. Almost anything can be made into a homie, including plants, minerals, food, clothing, furniture, air, light, and even living animals. Inanimate objects are brought to life and gain the ability to stand upright and move independently, their most notable feature being that they have a human face. Some of them can gain special abilities, such as a carpet homie becoming a flying carpet. Animal homies become more human-like, not only gaining the ability to talk and walk upright, but also fighting and using weapons. According to Big Mom, the more powerful the individual the soul was taken from, the more powerful the resulting homie will be. Additionally, homies will be more powerful if they possess a larger quantity of soul fragments within them, and can eat other homies to absorb their soul and become stronger.
