Does the Yami Yami no Mi give the user the power to absorb other devil fruits?
This isn't a yes hoặc no question. What I want is a source. It's fine if it's just speculation, but I've been seeing a lot of people claiming that Blackbeard was able to take the Gura Gura no Mi's power via the absorption abilities of the Yami Yami no Mi. What proof is there of this?
