nah, it still bugs me that baku figures out an eraser defeats this ink even if it's entirely possible that he experimented a bit with it and the paper while they were both drawing.

Baku is such a monster. The hard part wasn't how to figure the trick out, but how to counter it. Can't wait to see him blow my mind even more!

Why exactly does it bug you?

I'm guessing it is because Baku has to have knowledge about that specific magic trick. He may have done some research between his match and Kaji's, but it may look implausible to have that convenient info in such a small amount of time.
But I'm just guessing.
