User blog comment:Martialmaniac/How does "In" work?/@comment-25814498-20150627121123

I don't think we should question it to be honest, because to be honest, I don't see how Zetsu and In are even remotely connected. One involves stopping your aura from exiting your body and another involves making it completely invisible, so the only similarity is that both stop your aura from being detected. Other than that I don't see how they are similar.

As a matter of fact I was going to post something on the forum like "Nen: The Full Story", or some other gay title, where I tried to explain it in the best way I could, and all I said for In was that it bent the visible spectrum around it to make it invisible to the naked eye, but that wouldn't explain why Gyo would allow you to see it.
