A little discussion on Ichigo's powers

how is no one realising , that yhwach didn't hold back his quincy abilities- he held back his SHINIGAMI abilities.

What Yhwach did was take the quincy powers and IMMITATE shinigami powers. Which is the reason why Ichigos bankai was so baffling.

Because what it is, at its base is a Quincy Vollständig. with the key difference being that instead of absorbing the environment's reishi it pulled from Ichigo's inner reserves and then concentrated and amplified.

So yes- Byakuya was right.

It was a fake bankai, because it only imitated a quincy's take on it.

Which explains why, well there was nothing really for Ichigo to learn, to master about his bankai unlike other shinigami. Because the only thing too master was just the concentrated amount of spiritual pressure.

I know non manga readers won't know this as this was cut I believe from the anime because of screen time. But the reason Ichigo survived his fight with Kenpachi- aside Kenpachi basically limiting himself, is because of ブルート・ヴェーネ aka blut vene.

Ichigo was stabbed in the chest, bleeding out. When he reached out, when 'Old man Zangetsu' communicated with him, telling him they needed to work together- 'old man Zangetsu' made the decision to activate blut vene to stop the bleeding.

Because as he stated the only thing he cared about was saving and protecting Ichigo.

He only let Zangetsu , Shiro, teach Ichigo the bare minimum. Hell the fact Ichigo goes through the series into the TYBW Arc with only a Getsuga Tenshou and his amplifying hollow powers.

And for once it's not the bloody shounen disease nope.

It's a bloody stylistic plot related choice made by Kubo.

Because up until that point, we've never really seen Ichigo use his shinigami abilities.
