@ SuBash:

I put my words wrong. I dunno why I wrote what I wrote, but what I meant to say was that it appears to be present, like you said. That Ryûken was staring out of the window at the same time as Isshin told Ichigo the whole truth.

I hope Ryûken is alive though. If Ichigo comes home to his family to rest and build up energy before the "real" war starts, I hope Ryûken is alive and can teach him some basic Quincy stuff, like how to access and use Blut. I know he already used it twice against Yhwach, but it appeared to be unconsciously since he had no idea about his Quincy heritage at the time.

The manifestation of his Quincy powers said during the reforging of Zangetsu that he used Blut a few times by himself, i.e. during Ichigo's first battle with Kenpachi when he stopped a wound from bleeding. So it was likely him using Blut Vene to protect Ichigo from Yhwach's spirit weapon.
