"I want you to assassinate Kabuto Yakushi," Danzo said with a solemn tone. "He's betrayed Konoha and has killed Nonō Yakushi."

Ren was surprised to find out he was assigned to assassinate Kabuto, but he knew it was Danzo who was pulling the strings. He had tricked Kabuto and Nonō into killing each other, as he felt that Kabuto would become a threat to Root as he had become "too good" of the spies in Root.

"May I ask where Kabuto is?" Ren feigned ignorance.

"After killing Nonō, he was last seen speaking with Orochimaru, due to the fact that we've lost communication with him, we've assumed he's allied with Orochimaru and has betrayed Konoha. We found an underground lair outside Iwagakure." Danzo paused then continued, "Begin your departure within the next three days."

"No need for preparation, I'll leave today," Ren replied.

...

Standing in the outskirts of Iwagakure in a black coat, Ren walked around looking for an entrance near the location Danzo informed him of, but couldn't find anything. Not being able to find anything, Ren decided to question some people in Iwagakure.

...

"Hey, do you know anything about a bunker or anything of the sort?" Ren asked a young man.

"No, sorry." The man said with a little confusion as he looked at the foreigner.

The foreigner was Ren, but seeing as he didn't find any clues he continued asking until this little girl with bright green hair in a small dress told Ren, as she pointed in a direction "I saw a hole in the mountain near the forest straight ahead, I could feel some cold air from the hole. I didn't think of it at the time but it was actually a little strange compared to how hot it is outside."

"Thanks" Finding a lead on Kabuto's location Ren patted the girl's head and turned towards the area the girl pointed.

Approaching the hole in the wall, Ren suddenly felt chakra formed into a blade behind him, as he pulled out his sword.

"Who are you? Why are you here?" A series of questions came out of the young man wearing round glasses with grey hair's mouth. The young man was Kabuto as he pointed his chakra scalpel at Ren.

"I'm no-one you need to know about," Ren said as he put on his mask and turned around while wielding his sword.

"If you don't want to answer it, then die!" Kabuto proclaimed as he charged towards Ren.

Clashing his sword against Kabuto's chakra scalpel, Ren infused it with his chakra which started causing it to vibrate with the coating of electricity.

Being sent back by the chakra, Kabuto screamed, "Why are you attacking me? I didn't betray the village by choice! I was framed, Danzo is an evil person. You don't understand I know I'm innocent. I will live!".

"I know it Danzo is evil, but I have to follow his orders... For now at least." Responding, Ren jumped towards Kabuto.
