Ripi Ripi no Mi

The Ripi Ripi no Mi is a Paramecia type devil fruit that allows its user to cause events to repeat themselves. In doing so the user becomes capable of creating time loops and causing them or others to repeat events.

Strengths and Weaknesses
The main strength of the Ripi Ripi no Mi is its unparalleled ability to gather information. With the ability to continuously repeat the day, they can gather as much information as they want, test any attack, and learn an enemies entire set of moves. They can avoid whatever conflict they wish or repeat a task until they do it flawlessly. They can even train indefinitely if they wish. In battle they become perfect, able to dodge, interpret, and prepare for anything. The user is also capable of trapping others in time loops, casing a pattern of events to repeat themselves for them. This can be used continuously to trap them in an eternal loop of movement and thought, effectively stopping them for good. It can also be used in a singular way, simply making them repeat a movement once to hit them with perfect accuracy or otherwise.

The fruit cannot loop forever, it can only create one as large as a day. People can also be freed from the loops by touching seastone. The user also suffers from standard devil fruit weaknesses.
