I have absolutely no reason to defend Rainbow, but 'm saying this anyway.
Rainbow most likely owns the account, Kurosama and trolled us with it months ago before eventually giving up and going back to his old account.
If what you mean is that Rainbow left his main account and went to Kuro for a bit, I know that's not what happened.
Rainbow never stopped using his account for a longer amount of time than a couple of days, and I never noticed Kuro in those times.
But then, I never noticed Kuro at all. I didn't know he existed before this topic.
But rainbow is all furry.
Kuro is all anime.
Rainbow could easily fake that.
Anyone could.
Further inspection of Kurosama's posts yields that Rainbow and Kurosama were not posting at the same time, on any occasion when Kurosama had a drama topic. Mainly looking at August 28 to be exact.
I'm just going to mention, though I doubt it will matter in any way, that August 28th is my birthday, and Rainbow did know this.
