Explanations

Asher turned to Jiraiya and smiled.

"Are you alright, sensei?" he asks.

"Of course," says Jiraiya, "and since when have you called me sensei."

"You don't like it. Okay, I'll go back to Old Perv."

Jiraiya grumbled something and walked away. He went down the hall and headed for the room. He stopped at the door and turned back to Asher.

"You had better explain to me how you changed your sword like that and how do you have the Sharingan now."

"I'll talk," says Asher, smirking, "If you tell me about that technique you used."

"Deal," Jiraiya said before entering the room. Asher collected Tatsukiba and went after him.

He found Jiraiya sitting on one of the beds. Asher sat opposite him and waited for the old perv to speak.

"I think it would be better if you went first," he says while staring at the sword.

"Fine," says Asher, as he pulls Tatsukiba from her sheath. He them began telling Jiraiya about how he gained the sword from Minasa and how it changed because of his chakra. He told him about the world he was brought to and meeting Tatsukiba.

He continued to fighting Kisame. How Tatsukiba told him how to release more of her power.

When he was done, he stared at Jiraiya, waiting for him to say something.

He began to scratch his chin and said, "A Zanpakuto, huh. I've never heard of such a thing. What about the Sharingan? How did you acquire it?"

"When Orochimaru's scientists injected me with the dna into me, he also added the dna of the plant. They were hoping it would allow me to control myself. As a result, I can now produce the serum and use it to give myself or someone else new abilities. If I have the correct dna. That's why I took some of Itachi's blood. I wanted the Sharingan, so I took it. Now it's your turn. What was that technique."

"It's called the Rasengan," he said.
