Sorta. Super Saiyan Rage was definitely out of nowhere, not set up in any way, and didn't really make any sense. The aura was shaped similarly to Blue's, implying that it's somehow related, but Trunks didn't perform any kind of ritual, and he didn't train with any Hakaishin or Angel. I think stacking Kaioken on top of Blue came with some solid reasoning, though.

Indeed, the manga seems to imply that Vegeta attained Super Saiyan God without the ritual, just by training in the Room of Spirit and Time. That's sort of puzzling, at first. However, one only need to remember that Vegeta attained Super Saiyan Blue without first having the God form, both in the film and in the anime. Vegeta, the filthy cheating step-skipper that he is, skipping a step is consistent with his penchant for skipping steps.
Moreover, his skipping over God to get Blue is a more problematic step-skip than his subsequent skipping over the ritual to get God. In the former case, we see him jumping from step 1 (base form with no God ki), straight over step 2 (the Super Saiyan God ritual) and step 3 (Super Saiyan God), to step 4 (Super Saiyan Blue). In the latter case, we merely see him stepping back from step 4 to step 3.
In short, the fact that he can access Blue is the only justification we need for him being able to access God. The fact that he could access Blue in the first place is a much more puzzling matter, and one that permeates Super across all media.

This, however, is so straightforward that I don't understand how anyone could actually be confused. The Champa arc shows that Blue has a huge drawback, and in the following arc they find a solution to the problem. Too much ki is leaking out, so they learn how to contain it. Set up, pay off.
How does this not make sense? At what step does your ability to understand and comprehend basic storytelling fall off the map?
