Ryuke awaited patiently for someone from the Akatsuki to arrive. In one hand he held Sasori's heart chamber...

Kenshin appears on the shadows, walking out of it, noticing the heart of Sasori in Ryuke's hand, this meeting is entirely coicidential since he was on his way to Sunagakure to beat up Deidara and Sasori.
Who are you? Kenshin asked bluntly, staring down and studying the ANBU member.

Deidara came in flying via his clay bird and commanded it to land, which it did - he then picked up Gaara's body, dragging it over to Ryuke.

I'm here for Sasori's heart, un.

Ryuke turned his gaze gently towards Kenshin, observing him, then sat down on some nearby rubble.

I am a member of the ANBU Black Ops. My name is of no concern. Im awaiting the return of the Kazekage's body... for Sasori's heart...

Answering Kenshins question, he turned his gaze at Deidara.

Place him on the floor, I shall then place the heart on the floor, and take the boy. The heart is imbuned with a ice trap, should i be attacked the heart will shatter beyond use. Upon being 1000 meters away, the ice shall disappear. I shall not tolerate any tricks.

Oh, so that is Sasori's heart, well that's one thing done in my list, the next person to beat up is you, Deidara.
Kenshin takes out his chakra katana, teleporting next to Deidara and thrusting the chakra blade into his shoulder, slicing his arm off.

Deidara snarled and twirled 380 degrees with his leg up only to roundhouse kick the side of Kenshin's face brutally before placing Gaara's body on the floor, the other hand chewing on clay to make five small clay spiders and let them crawl on the floor unnoticably towards Kenshin.

QUICKLY, UN!!

Ryuke seemed un-interested in the fighting, walking gently over to Gaara, he picked him up, and placed the heart on the ground. With it he placed a single, clean icy blossom, so perfect it appeared real.

That is for Konan (he said calmly) See to it that she gets it

With that Ryuke walked away.

Kenshin avoids the roundhouse kick by ducking, he quickly sheathes his chakra blade, taking out several senbons from his coat, he throws most of the senbons at the clay spiders, pinning them to the ground, then he jumps over Deidara, standing behind him, he plants a senbon at Deidara's neck at a pressure point.
Heh, you have eight seconds until you pass out, make do with your time.
A shadow of a smirk forms on his mask, seeing what Deidara will try to do.

Deidara lunged his hand over to grab the heart as gently as possible before placing it in his coat for safe keeping and did a few handseals with his hands and muttered. The clay spiders of course exploded because of the pins.

Nendo Bunshin...

A puff of smoke appeared around the area, once it cleared out, Deidara was still standing as the clay bird took off for some reason. Deidara got into a fighting position and stared down at Kenshin, creasing his eyebrows and narrowing his eyes to get a better look at Kenshin but didn't say a word - once the pins were stuck behind Deidara's neck, it turns out to be a clay clone while the real Deidara made his escape, which is why the clay bird took off. As soon as the pins made contact with the clay clone's neck, it caused a massive explosion of course, just enough to desintigrate Kenshin out of existance.

Kenshin teleports away before the explosion can happen, his coat was burned off while there were several burns on his chest, his face showing, he decides to concentrate chakra on his wounded areas, healing them up, smirking because of the thought that this is a way for Deidara to get revenge on him for his humiliation on Deidara in front of Pein, Kenshin takes his time to take a few breath, eventually teleporting to the direction of where Deidara went.

Deidara had already took off and headed to the Akatsuki lair.
