The Lightning Uchiha

Itachi! : The Perverted Sensei

"Itachi! I'm going to kill you!" Sasuke yelled out.

"Huh, hey Itachi, that kid kinda looks like you." the blue-skinned guy said.

"That's my little brother and my little cousin," Itachi said with a dull look.

Raiden glared at Itachi for a moment, then looked to Naruto, "Naruto get out of here!"

Sasuke went through hand seals before making a Chidori and charging at Itachi, attempting to kill him. But Itachi wasn't worried about it and slapped away Sasuke's Chidori before kicking Sasuke to the other end of the hallway, cracking the wall.

"Sasuke!" Raiden and Naruto yelled out.

Raiden and Naruto ran to help Sasuke, but the blue man blocked them.

"This is a fight between siblings." He said.

Itachi picked up Sasuke by his throat and held him against the wall. Sasuke looked into Itachi's Mangekyo Sharingan before he started screaming and thrashing around, but Itachi just held him there. Sasuke screamed for another moment before he went limp in Itachi's hand, and Itachi dropped him to the floor in an unconscious heap.

"No!" Raiden screamed before speeding past the blue man before he could react and raced to Itachi, going for a roundhouse kick to Itachi's head, but Itachi just caught it with one hand without even looking.

Itachi then threw Raiden back down the hallway, landing next to Naruto. Raiden groaned in pain when suddenly the hallway changed into a flesh-like material. It looked like they were inside something's intestines. 

"It was a nice try distracting me with a beautiful woman, but the mighty Jiraiya won't fall for something like that. You two aren't going anywhere." Jiraiya said from the end of the hall where Sasuke and Raiden came in from holding a woman over his shoulder.

"Kisame, we're leaving," Itachi stated before they ran down the hall and around the corner. They escaped by blasting a hole in the wall with some kind of black flames.

Jiraiya was checking on Sasuke when he was suddenly kicked in the face and sent flying by Might Guy, who had followed Raiden and Sasuke to bring them back to the village. Jiraiya handed Sasuke to Guy, who turned to leave.

"Alright, Raiden, it's time to go!" Guy said.

Surprisingly, as Raiden went to leave, he was stopped by a hand on his shoulder belonging to Jiraiya. 

"Actually, I think that Raiden should stay with me," Jiraiya said, stepping up beside Raiden.

"What? Are you sure?" Guy asked.

"I'm certain. Don't worry; you can trust me with his safety," Jiraiya said with a smile.

"Of course, Jiraiya-sama. I will be taking my leave now." Guy said, jumping out the hole in the wall and sprinting back to Konoha.

"Um, Jiraiya-san. Why did you want me to stay with you and Naruto on your mission?" Raiden asked, confused.

"That's because you remind me of my previous student, the Fourth Hokage," Jiraiya said, looking down at Raiden, whose eyes widened to enormous proportions. 

"The Fourth Hokage?! But there's no way I could be like him!" Raiden protested.

"On the contrary, you are a lot like him. You are cool-headed in stressful situations, you are a genius who is already making his own Jutsu, and you are both incredibly fast." Jiraiya said, shocking Raiden with the similarities. "Now, we should probably get moving. I don't think we'll be very welcome here anymore."

Jiraiya and Naruto went into their room and came out with their bags when Naruto noticed something.

"Wait, Raiden doesn't have any supplies packed," Naruto said to Jiraiya.
