Somehow, they're still trying to prevent her death at chapter 34, safe to expect that there are probably more situations like this chapter again. They reach a situation exactly like Itsuki's vision, but somehow Umi was not in the exact same location, so that was prevented. It's not clear if her numbers disappeared, but then a few panels after that, an "accident" happens and Tarou gets hurt instead. He wakes up, but the amnesia arc starts. (not too happy about this trope tbh)
