I'll make it only 3 rounds as to not waste your time.

As you spun to counter Hannya, the moment you grabbed his fist with the same side hand, Hannya would take his other hand and would trap your wrist while simultaneously sliding his right foot back in order to partially face his right side at a diagonal angle. coupled with the lifting of his left elbow, your hold on Hannya's fist wouldn't be strong enough to hold as he turned his entire body. The entire fluid motion would be Hannya trapping your wrist as you trapped his fist while he goes to escape your trap and put his elbow against yours.
"His taijutsu is sloppy, were you the one who taught him Shin?" Hannya asked.
All the while, with your back toward Shin, his attack would continue unhindered. You'd be hit with his punch since you only turned around to deal with Hannya first, with both punches being executed at the same time, the target would change from your solar plexus to your spine on your lower back with regard to Shin. The strike would be mildly rattling but not quite enough to break the A-ranked genjutsu.
"Oi, just where exactly where you aiming with that insult?" Shin said defensively.
With his elbow braced under yours, Hannya would do a small circular motion which would switch the positions of the elbows so his was on top and yours on bottom. He would then push down and fall with you as you head to the ground from the pressure of Hannya's entire body on your elbow. Your body would naturally move with it as not doing so would cause your elbow to snap. Hanya would kneel one leg into your back against your shoulder as he holds your arm up with you face down in the ground.
