Kishiru Kishiru no mi
English name: Creak Creak fruit
Namesake: "Kishiru" (軋る) means something like "to creak" or "to grind" which in this case refers to ropes similar to those on ships making said sounds when thighten with pressure.
Appearance: A green-ish pear with weird, white, rectangular swirls all over it. It's rather greyish stem has the appearance of a simple pointing arrow.
Desire: Devil fruit power derived from wishing to be able to escape or simply leave physically and metaphorically akward or unwanted situations.
This fruit grants the user a supernatural escape rope, turning them into a escapist user.
In depth description:
Upon consumption the user is granted a devil fruit power in the form of a supernatural tool growing from their body.
And this tool... is a rope! (sticking out from their ass)
Now of course this isn't some regular rope that looks like a limb cat tail on the user's back, it posseses unique properties and purposes, specifically when used as an emergency exit.
Simply put: After the rope is tied to something,no matter if it's an object, a person or even seemingly a spot in the air, it will activate it's special abilities and can not be removed from that spot by anyone but the user.
Should the user now move further away, the rope will not only extend without any limits further and further to make up for distance, but will also phase through everything possible in order to reach the user in a straight line (and yes, everything means everything including light, so the rope turns invisible during that period).
Now to get to the actual usefull part of it, the rope can act as a sort of emergency button they can activate or deactivate whenever they feel like it in order to get dragged right back to the starting point at high speeds. During all of this the user will also share the intangibility of the rope allowing them to ignore everything as long as they get dragged along.
Weaknesses:
Standard devil fruit weaknesses for the user's regular body. Should their powers also deactivate when their rope is phasing through something, it would simply get stuck in that and not enlongate anymore until the negation of the user's powers stopped.
The rope isn't able to drag the user wherever they want and can only work in one way which is the spot it's end is tied to, this means that whatever the rope is tied to will stay unmoved no matter what the user does. (The user also has to manually tie it to somewhere in the first place)
While getting dragged along the user's senses are essentially useless since their body can't interact with anything just like their rope
