Episode 580.. The ending.. The light that made most believe its ichigo but Haven't you guys got this strong gut feeling that its Yachiru? Or it just me? Please listen to what i have to say.
1. The author made it a point to emphasize the disappearance of Yachiru through kenpachi's exaggerated actions not just simply because kenpachi is worried about her so that has got to be some impact on how she re-appears right? I mean after all the years together, it has got to mean something.
2. The possibility yachiru has a bankai and only zaraki knows it. We all have to admit she is still shrouded with mystery. A weird shikai, an undeniably strong spiritual power, and just being around the monster zaraki takes a lot out of someone and she is just a kid. Plus this is the last arc, so there's a high chance that the author will reveal yachiru in a amazing way. She might even be potentially crazily strong and become the prodigy that takes after zaraki. Just sayin..
3. My strongest and most visual clue. The last page of chapter 580 shows an explosion in the shape of what appears to be a skull. Indefinitely, everyone thinks its ichigo trying to bust out his new attained powers on the girls. But its not, and the previous chapters were a helpful clue that it was yachiru. Her shikai included 2 cretures; one bone-like and one fluff-like. The bone like creature is one clue that points to the physical manifestation of yachiru's pink spiritual energy which everyone thought was cat like in the anime but it was actually more skull like.
Here is a link showing her spiritual power in anime in gif;

And compare it to the last page of the chapter;

Its just a say. people may disagree but i just had to put it out there because literally all the sites i go to, had little talk and faith about yachiru. I'll be ashamed if i'm wrong after being so passionate. Thanks for reading through till the end! ^^
