Was finally free of the accursed light barrier, having escaped through the relatively small hole that his inhaling maw technique had created. It was nice to have his full arsenal of jutsu's back, and not have his chakra absorbed, as his Edo Tensei body rapidly regenerated some much need chakra. The lack of inhibiting space-time ninjutsu was also nice. However, things had no gone fully according to plan, as the Yondaime was situated somewhat outside the barrier, and not air borne. With his sage sensing picking up the behemoth just behind him. Not having the time to do much of anything, the Yondaime would go to old reliable and spawn his susanoo with yata mirror and all the fixings, although it lacked a weapon and was about the size of Itachi's as per usual for the Yondaime. The entity was spawned so the face of the susanoo and shield would face the onslaught of what was to come. The resulting susanoo would block the photon beam which would shoot at him after he had escaped (confirmed with Keito) and the strikes from Kaze.
As stated many times over, Itachi could spawn a susanoo before lightning struck him and lightning traveled at about 220,000 miles per hour and a susanoo manifesting was faster than that. So considering the speed of his defense, the Yondaime would survive. Although even if he didn't spawn it, it was arguable Kaze's attack was futile anyway, as the armor of sticky gold could stop the Hyuugan strikes, and the steel armor around the Yondaime which was still around him since he failed to assimilate the light. Although they wouldn't be settling said argument today.
So Kaze would likely crash into the Yata Mirror, considering he didn't know it was the Yata Mirror, and he had the boons of hercules sage mode, lightning armor, and the second gate. So if Kaze didn't think he could break through it, then he probably didn't think he could break through susanoo in general. Combined with the speed he was going, it would make it incredibly hard to pull out of the attack. So Kaze would realize the error probably around the first few strikes. Of course, the Yondaime won't be one to tell Kaze what he was going to do, but either Kaze would somehow stop his attack, or futility strike the mirror. But what was certain was that they would both be out of the barrier and close to each other.
Either way, what Kaze would do wouldn't stop the Yondaime. Kaze was near him and very dangerous, thus the Yondaime would turn his body (while keeping the susanoo in place) and as he was turning, a loud whistle would escape from the Yondaime's lips which was started before he even started turning. As soon as Kaze heard the whistle, he would be trapped in a genjutsu. Kaze would find himself immobilized, as ropes held his body in place, not able to break free regardless of his impressive strength and he would find his conscious fading away, putting him out for the fight. The genjutus also fed the men hallucinations, and he would find himself in a redish world, not able to see the Yondaime, or his beetle as his body parts melted away. The Yondaime didn't think he could break the man mentally, but the illusion effects would disguise the Yondaime's actions.
Since Kaze was pretty freakin close to him, combined with the speed of sound (340 meters per second) Kaze was likely caught. So unless the man was deaf this entire time, could rupture his eardrums in miliseconds, or had some secret Ototon, he would likely be caught. From there it would be up to Kaze to break out. The Nanabi wouldn't be an option since he had not mastered the beast. His summon would also be caught in the genjutsu, since only a specific type of bug in the anime is immune to genjutsu. Also since his beetle was more of a summon than some random insect, and there is no wiki page describing it's genjutsu immunity, it too would be caught and thus unable to break Kaze out, not to mention it was sentient enough to talk. With no outside help, it would fall solely on Kaze to free himself. Since both were in Sage Mode, he couldn't use his senjutsu to overpower the Yondaime. Thus it was Kaze who seemingly no genjutsu at his disposal (according to wiki, may be wrong) or even if he did, would have to overpower a man well versed in genjutsu, being an Uchiha and all that. The Yondaime was quite confident his genjutsu would be greater, not having much faith in the Hyuugan bloodline. To add further dismay, this genjutsu is particularly hard to get out of. It trapped both Itachi and sasuke, genjutsu masters, and required them to use sharingan genjutsu on each other to cancel it out. Kaze lacked a partner and genjutsu. While the Yondaime lacked a flute, being an Otokage and master of Ototon, would allow the whistle to work as a substittue.
Even if the man did find a way to escape, he would still be stuck for at least some amount of time. In that time, the Yondiame would complete his turn, lift up his arm and blow a huge amount of Dokuton "smoke" into Kaze's face. Naturally he allowed this poision to pass through his susanoo, but his susanoo would still block any outside source. Said Dokuton would work to erode the man's chakra network, killing him within a short amount of time, and would spell doom for the man. Thus Kaze was faced with a near instantaneous defense, faster than lightning, followed by a sound genjutsu which is the speed of...sound and then a second or two later, blasted with Dokuton. That was quite a bit to deal with, but Kaze seldom disappointed.
