God damn, I do not remember this manga moving so fast!
The final round of Genkai's test is a tournament, where the first three battles are quickly resolved in one chapter. The next few battles take about a chapter and a half each. Randou is revealed, conveniently as the last opponent in the battle. Yusuke, being the protagonist, wins without too much trouble, and his training under Genkai happens off-screen. We then jump almost immediately into the Saint Beasts Arc, during which Hiei and Kurama reappear as new allies, setting the standard for the future of the manga.
To continue being silly by guessing at YYH characters' Nen types: We don't really see Kuroda or the Chinese guy do anything, so it's hard to say for them. Musashi doesn't do much in terms of special attacks, but he seems capable of Zetsu, In, and En. Kibano is clearly an Enhancer. Kazemaru is an Emitter, with some talent in Manipulation for his shuriken. I guess Randou would be a Specialist, since his ability to copy techniques is like a variant of Chrollo's book. I guess Kurama is a Manipulator, as he's shown to transform an actual rose into his whip - I couldn't remember last volume if he wielded real roses or summoned them. Genbu... I have no idea. He actually just has Pica's Devil Fruit from One Piece.
