Dragon Ball Super has revealed a small (but possibly important ) new detail about how the powers of Angels work. That reveal was found in the rough sketches for Dragon Ball Super manga Chapter 71, in which Goku continues training with Whis to better master Ultra Instinct. Whis apparently enlightens Goku as to the difference between the version of Ultra Instinct the Saiyan is using, and the version that the angels use. Whis asks Goku what the difference between him and angels are, and the apparent answer is that angels are always in the Ultra Instinct state, through perfect stability of the heart and mind.

The roughs are out for DBS ch.71: “Heeta’s Plan”. Whis asks Goku the biggest difference between him and the angels. “A halo?” No, Whis says it’s how angels are always in the Ultra Instinct state. Goku shouldn’t need to transform to do it. https://t.co/weCwRNnqOz pic.twitter.com/tGrAFxriZK
