- "Soru" (ソウル?) is the Japanese pronunciation of "soul".
Strengths and Weaknesses
The fruit's power of soul manipulation, as demonstrated by Big Mom, consists of drawing out and manifesting fragments of humans' souls into a tangible, somewhat viscous, light-colored substance, which the user extracts by grabbing and pulling it out. This is effectively and referred to as stealing from a target's very lifespan, the amount of which being determined by the user, up to tens of years at once and down to the second if desired. Thus, if they lose too many years at once, a victim may be killed instantaneously. However, the extraction process does not seem to be painful to its victims, at least when they are only losing small portions of their lifespan.
By infusing them with soul fragments, the user can "humanize" objects and living animals. Recipients of these soul fragments (which Big Mom refers to as "Homies") develop human-like intelligence, with inanimate objects even gaining a life of their own, and undergo transformations to more closely resemble humans; though objects will often merely develop human faces, animals will have their general physique affected to varying degrees. If a Vivre Card is infused with a soul fragment, instead of becoming anthropomorphic, the card will exude a bright aura which only homies can see.
In addition to stealing and using the souls of other people, the user may manifest their own soul into living fragments (which Big Mom refers to as "Incarnations") in the form of roughly human-sized, black, somewhat humanoid blobs, which possess limited sentience and can absorb people's souls as well.
The power to infuse soul fragments cannot be used on living humans or corpses. Furthermore, the emotional state of a target affects the user's ability to take their lifespan away in a currently unexplained manner; for example, if they display fear of the user, the target is rendered vulnerable to having their lifespan stolen. Similarly, if homies experience extreme fear, they instantly die and wither away. Homies cannot attack anything infused with the user's soul, even if such an object is in the hands of an enemy. Otherwise, the user experiences the standard Devil Fruit weaknesses to water and Seastone.
Big Mom has imposed a toll on all citizens of Totto Land, forcing them to give up a month's worth of their soul and lifetime every six months or leave. Those soul fragments are collected by her "Incarnations" and sprinkled all over the islands of Totto Land, where they settle into random objects or animals to turn them into homies. She has also used the power to kill people by taking a lethal amount of lifespan from them.
Big Mom's own soul, which is extremely strong, prevents all homies from approaching anything that is imbued with it.
- The Incarnations (化身 Keshin?) are large, black, humanoid blobs who collect the Totto Land residents' biannual payment of a month's worth of their lifespan. They are made from pieces of Big Mom's own extremely powerful soul, and are themselves capable of extracting other people's souls. They are also capable of human speech and are intelligent enough to understand basic orders.
- The homies are the result of infusing the collected soul portions into non-human animals and objects, who are subsequently anthropomorphized. The fragments cannot revive dead humans or enter living ones. Also, they are unable to approach something infused with Big Mom's own soul, the incredible presence and power of which only they can sense.
- This fruit's power resembles that of the Kage Kage no Mi, as it can take a normally intangible part of a person (in this case, souls instead of shadows) and insert it into something else, which becomes animated. However, while a Kage Kage no Mi user takes the shadows of humans and can insert them into any other form of life, even other humans and corpses, a user of the Soru Soru no Mi cannot insert the soul fragments into another human or a corpse.
- This fruit is the second one to display soul-related powers, the first one being the Yomi Yomi no Mi.
