Dark Release: No real idea at all. Swift Release: Wind + Yang, Wind is something people affiliate with speed, it's also used in Dust Release which shares the same romanisation with Swift Release so maybe some connection in that regard. The yang chakra enhances the body, not much to be said. Also the smoke might be some form of indication of wind? Maybe, maybe not. Steel Release: Earth + Yin, Steel Release seems quite obviously earth, considering, in real life steel is made up of iron and carbon, so the Yin Release creates some other mineral or whatever you wish to call it and in the process of moulding the Steel chakra the Yin fuses with the Earth's minerals to make Steel. Crystal Release: Water + Yin, Crystal Release seems to have some affiliation with Isobu who can use Water Release, and Crystals are obviously solid(this is where Yin comes in), similar to ice which is crystalline. Obviously there seems to be some earth element in it, but due to the water in it the lightning possibly was able to travel all across the crystals in an instance, the entire crystal is attacked.
