Gesui Gesui no Mi

The Gesui Gesui no Mi is a paramecia devil's fruit that allows the user to turn into a living sewer, making them a Sewer Human. This devil'a fruit is often confused with the Shiro Shiro no Mi, which allows the user to turn into a castle. There is no current user, and this devil's fruit is located in the Devil's Fruit Vault.

Strengths
Since the user is a sewer, they are incredibly durable because they are made of stone and metal. This means that the user can take more attacks than a normal person. The user's personality gains complexity and depth just like a sewer.

Weaknesses
The user is weak to fire because their sewers are always filled with noxious, toxic gases that are flammable. Other than that the user suffers from standard devil's fruit weaknesses.

Attacks
Sewer Cannon - The user shoots out a glob of toxic sludge or a jet of fire (after igniting themselves from the inside) based off of their preference.

Gesui - This is the user's signature move. The user creates a massive pipe opening on their stomach. The attack headed towards them will get absorbed by this pipe. The user can then turn this into "sludge", and they can use the sludge in Sewer Cannon.

Pipe Form - This is the user's ultimate move.
