Chapter 23: Kekkai Genkai

"Anyway, you said you knew something about why I am getting sick?"

Kakashi shifted on his seat so that now he leaned forward, his elbows digging into his knees.

"Tsunade-sama has a theory."

"And?"

"She believed you have a Kekkai Genkai."

"Is that some sort of illness?"

Jiraya roared with laughter, while Kakashi closed his eyes in exasperation.

"No, it's not. Sometimes, I forget how much you don't know. Still…not knowing what a Kekkai Genkai is. That too with me around."

"Well, then explain!" Kohana snapped.

"Alright. What am I known for, Kohana?"

"Being late." She was feeling giddy.

He glared at her silently.

Kohana giggled, "Okay, your Sharingan. You've copied, what, 1000 jutsus?"

"Hai, my Sharingan is a Kekkai Genkai. It's a special technique that allows me visual prowess incomparable to anyone, but the Uchiha."

"You only have it because Obito gave it to you. You're not an Uchiha."

Jiraya commented, "The Sharingan doesn't work as well for Kakashi as it would for an Uchiha. Nevertheless, he is remarkably skilled enough to wield it. It requires precise control of multiple chakra natures. Gaining that control becomes tougher when the Kekkai Genkai is not passed down genetically. Which, fortunately for you, is not the case."

"Okay. So, the both of you think I have a Kekkai Genkai. Why?"

"Your mother had it too. In fact, her whole clan possessed it. You started showing signs when you were six. You may not remember, but you fainted frequently. It wasn't until I researched your mother's background that we realized you were reacting to your Kekkai Genkai because you had no control over it."

"But, what is it?" Kohana insisted.

Kakashi replied, "It's based on medical ninjutsu. You're able to transfer your chakra to others in large amounts. Your chakra is able to permeate through space and fuse with another's reserve. It's an extraordinary talent. Unlike Tsunade-sama who has to rely on Katsuyu to carry her healing chakra to others, you only need to be in close proximity to provide yours."

Kohana let out a whoosh of breath. She said slowly, "That's amazing.

"It is. At the same time, it's also highly dangerous. That's why it's sealed."

"What!?"

Jiraya explained, "I placed a seal on you so that it wouldn't disturb your physical health. However, we don't have much familiarity with this Genkai and the seal is already weakening. Tsunade and I've decided it's time to teach you how to control it rather than perform another sealing. Like I said, Tsunade's not sure that would work anyway."

Kohana nodded, "Okay. Are you going to teach me?"

"No, I won't have time. Kakashi will do it."

"Oh." Kohana vividly remembered her last training session with the silver haired man. She wouldn't soon forget the soreness in her legs after she was forced to run laps.

Kakashi smirked as he recognized her tension, "Don't worry, Kohana. This is a matter of mental exertion."

Kohana sighed in relief, glad that at least this time her body wouldn't scream with aches.
