Roka fruit

The Rokakaka Fruit (commonly abbreviated as "roka" in-game) was an item used to reset your Stand. It was very common, and was an E tier item.

It could also be bought from the Shop for $500. In the latest update, it has since been removed and replaced with a Pucci NPC that will reset your stand upon talking to him.

The Rokakaka Fruit's appearance was that of a spiky red object. That's pretty much all.
