Susu Susu no Mi

The Susu Susu no Mi is a Logia-type Devil Fruit which allows the user to create, control, and transform into soot at will. It was eaten by Karasu.

Etymology

 * Susu (煤) means "soot" in Japanese.

Strengths and Weaknesses
This fruit's main strength is to create, control, and become the natural element of soot: fine black particles consisting mainly of carbon and created by combustion (i.e., burnt wood, coal, or other once-organic matter). When transformed into this powdery substance, the user becomes intangible like most Logia users and invulnerable to physical means of attack like gunfire, while at the same time being able to float in midair thanks to the lightness of the soot. By condensing the soot that makes up their body (or is additionally created) into a semi-solid state, the user may give it any shape they desire.

No weaknesses are known of this ability apart from the standard ones for Devil Fruits and Logia types.

Usage
Karasu's go-to way of using his powers is to divide his body into a murder of crows made of compressed soot. In this divided state he can fly at high speed, relay information (e.g., by delivering newspapers) or generally communicate by speaking through individual crows, as well as carry allies with him through the air, with a single crow being able to carry an average-sized human.

In combat, Karasu is able to disarm enemies en masse by snatching away their weapons with the crows, as well as attack by having them fly into and peck enemies in rapid flocking assaults.

Techniques

 * Karasusu: Karasu's most common technique, which allows him to break his sooty body apart to produce crows, whether a single one or an entire murder of crows. These birds made of compacted soot appear to carry Karasu's consciousness (seeing as they are made from his body) and can serve various tasks, including combat-oriented ones like attacking and disarming enemies. The technique was first properly shown when Karasu disarmed members of the Peachbeard Pirates during the Lulusia Kingdom's liberation but was not named until the Revolutionaries' assault on Mary Geoise, in the Domain of the Gods. The technique's name can be seen as a pun based on the Japanese name for crow ending with the syllable -su (which if doubled means "soot"). In the VIZ manga, the technique is called Kara-Soot.




 * Obelisusu: An attack where Karasu moves swiftly past a potential multitude of enemies while transformed into soot, leaving traces of the substance between their feet. He then causes the residual soot to shoot upwards in the shape of thin, obelisk-like stakes, causing piercing damage to said enemies while sending them flying. The technique was first seen when used to take out random government agents in Mary Geoise. The name is a pun on oberisuku (オベリスク), the Japanese way of pronouncing the word "obelisk" (with the first two kanji derived from the more obscure term hōsenchū (方尖柱), also meaning "obelisk"). The VIZ manga calls the technique Obeli-Soots.




 * Karasu Renkon: An attack whereby Karasu breaks his body apart into a murder of crows to assail a specific opponent, by having the crows rapidly fly at and peck the latter in rapid succession. The technique was first seen when used by Karasu to attack Fujitora, forcing the marine admiral on the defensive. The attack's name is a pun on renkon (蓮根), meaning "lotus root" (with the kanji ren (蓮) for "lotus" replaced with ren (連) for "lead/join/connect" and the kanji kon (根) for "root" replaced with kon (魂) for "soul/spirit"). In the VIZ manga, the technique is called Crow Soul Lotus.

Trivia

 * This is the second known Devil Fruit with a name whose first part comprises a single quadrupled katakana: su (ス). The first such fruit introduced is Streusen's Kuku Kuku no Mi.
