Here is my main problem with the fact that people seem to believe that Ichigo no longer has a Fullbring. Fullbring, like Shinigami powers, are part of their user's reiatsu. Ichigo was able to use it due to the reiatsu that had been building up in him, in conjunction with the soul of his badge. When his Fullbring completes, his badge gets the exact same X symbol as those things on Ichigo's wrists and chest in his new Shinigami form.

Then, in this chapter, when Ichigo throws Kugo and Kugo is thinking about Ichigo's improved power. He comments on how the Fullbring he "gave" Ichigo made him stronger. The panel in which he says that zooms in on the X shaped marks currently on Ichigo, obviously hinting at that being a remnant of his Fullbring. This page is proof

My thoughts is this. Kugo absorbed Ichigo's powers, all of them, by sucking out Ichigo's reiatsu with Cross of Scaffold. Then, when Ichigo regained his reiatsu; his Fullbring AND Shinigami powers returned. According to Tsukishima, Ichigo had already merged his Shinigami and Fullbring powers. So when his Shinigami powers returned, so did his Fullbring.
