They finally gave a reason on this being the 3rd series

So to me, the hypest thing in the newest episode (14) was the introduction of , as it finally gives a reason for how it's the 3rd To Be Hero series and an introduction to Unc or Futaba coming from the previous series. It's how Unc ended up meeting Futaba previously iirc , so it wouldn't seem like an ass pull either. I know most are thinking it is a new theory for X, which is also a very strong theory too, but this is a way for those two previous protags to possibly show up was what was likely intended 🙂

@Shilohzz from what I heard, absolutely not. They are a completely different vibe, more of a gag comedy with some action. Plus the animation (which is arguably the biggest draw for TBHX) is no where close to this level or even as creative. I'd only watch the two if I was a die hard super fan (even more than a person who has seen all the PVs for TBHX) with too much time on my hands😅, since they were said to only make a cameo at most and not be part of the main story🙂
