Dentatsu Dentatsu no Mi

The Detatsu Dentatsu no Mi is a Paramecia-type Devil Fruit that allows the user to become a Relay Person. They can create a mental conversation among a group of people that have been marked and intercept the thoughts of a person who has been marked. It was eaten by Sirena Del Vil of the Longtail Gang.

Advantages
Sirena has used the Devil Fruit to exceptional levels. The primary ability of the Devil Fruit is that it is allows one to create a conversation that can be had by multiple targets that she has placed her marks on. The marks take the form of Sirena's initials in a circle. Sirena can safely control this ability as long as 10 or less people are in it.

The second major ability of the Dentatsu Dentatsu no Mi is that they can relay the thoughts of a marked person into their mind and know what they are planning or about to do. Sirena uses this ability in a manner similar to Observation Haki to prepare to dodge before the attack is launched.

Disadvantages
Standard Devil Fruit disadvantages apply.
