Darui approaches the battlefield, his blade strapped to his back as always. He sees his opponent approach and start a set of handseals, immediately Darui hardens his stance preparing for an attack. Afterwards the floor starts to rumble a bit, informing Darui of an earthen attack; the floor breaks apart in front of the opponent and a dragon starts to arise. Knowing the technique and it blocks the view of Castiel, Darui takes off straight forward towards the incoming giant projectile. As the dragon nears which would be respectively enclosing faster than Castiel intended, Darui creates a single pillar underneath himself which catapults himself upwards using his forward momentum to allow him to run along the incoming dragon as a sort of walkway granted he produced chakra within his feet.

Nearing the end of the dragon, as Castiel would be breathing into the tunnel, therefore having his guard down and his head down, not being perceptive of his surroundings, mainly above, Darui leaps off the dragon while completing a set of hand seals.
Wood Style: Binding Tree!
Of course Darui doesn't know wood release, but that wouldn't stop him from quickly trapping his opponent in a Genjutsu based on wood. His opponent had no knowledge of Darui's capabilities, therefore he could not predict the jutsu in fact used was a fake, an illusion. Castiel wouldn't undergo the full intended Genjutsu purpose as he had no sight of Darui, so the disappearing part of the Genjutsu was null, not giving away the most obvious fact of the illusion, lessening Castiel's chance of realizing. Albeit that, roots erupt quickly from the ground underneath Castiel, wrapping around his body, growing a thick tree around him, encasing him in it's bark. Struggle he may, a bean pod arises from the ground in front of him slowly opening, revealing Darui with a Kunai in hand. Words left Darui's mouth.
Secret Wood Style: Pod Sprout!
Darui then proceeded to slice Castiel through his jugular vein, allowing for a slow, painful death.

Description: Similar to Illusion Technique: Tree Binding Death, the user will do the Dog → Hare → Snake → Ram hand seals and trigger an illusion where the user first disappears, while the target sees several bean vines growing from the ground around and beneath him. These vines bind the target body, lifting them into the air. Then a bean pod rises from the ground to reveal the user, ready to strike. In reality, the opponent is immobilized by the illusion, allowing the user to strike.
As the Genjutsu sets itself in, Darui would be closing in on the ground after having thrown 5 Kunai at Castiel as he's hindered due to the genjutsu. 3 laced with explosive tags, they were aimed in an omnidirectional pattern, including North, West, South, and East of Castiel, even fly spaced out in 2 meters of their respective directions of Castiel, the last Kunai aimed directly at the top of Castiel's head. The West, East, and Middle Kunai are the three with explosive tags. Landing at a closer mid range to Castiel, Darui takes off to his right admiring the explosion if successful but never taking his eye off the opponent.
