Damn nice descriptions o__o, I'm going to have to try and step up my rp
The knight stood still as Itachi tossed a scroll into the air, producing a giant dragon made of raging flames. Shisui had just tossed the kunai with the bomb tag attached to it as the knight had begun his counter. A pillar of stone rose up beneath him swiftly, launching him backwards, away from the two projectiles (I'll assume you are entering long range [15+ meters], since we didn't state how deep/shallow into mid range away from one another we started). As soon as the knight created the pillar and began moving backwards, Shisui pooled doton chakra beneath his airborne opponent, shaping it in a particular way to force jagged spikes of rock to rise up from the earth, threatening to pierce through the knight's armor and body. Shisui approached the house as he channeled chakra through the ground, running in an arc to the right. As soon as he got to the deck of the house, he produced three shuriken and jumped atop the second section of the roof (
see picture in my first post, its in a spoiler.Let's say it's 4 meters to the top of the first section of the roof, 5 to the second) and blew fire onto them as he threw them towards the knight (Shisui would be mid range away from the knight atop the roof). As this happened, Itachi jumped forwards into the air about six meters high, and three meters forwards. He gathered superheated chakra in his lungs, then expelled it through his mouth in the form of three massive fireballs. The fireballs would be in a triangle-like shape as they approached, each slightly spaced from one another. This would make them all hit in nearly the same location, yet provide a small hole in the middle for Itachi to see past them towards the knight. If they were to hit anything, they would create a large pillar of fire reaching six meters high. If all went according to plan, the stones would pierce through the knight almost instantly as he retreated, and Itachi would be in the air preparing his fireballs by that time. The shuriken would approach the knight right before the fireballs would hit him.
