Fuck!
Of course, that would be too fast. Kushina might accept kissing and cuddling now, but she definitely would not accept going any further.
The little tomato needed a little more tending before she ripened. An experienced grower never picked an unripe fruit.
Karn patted the cushion beside the table, motioning for Kushina to sit down and talk.
"Kushina, I think you need to get stronger now. In this world, only strength can truly protect you. If you're too weak, you can only let others push you around."
Kushina rather agreed with that. She lowered her head in frustration and said, "I know, but right now, I only have talent in sealing jutsu. Although I learned Monstrous Strength from Sister Tsunade, if I want to get stronger quickly..."
"There is a way," Karn interrupted. "You know Nawaki, don't you? Tsunade's younger brother."
"I do. Nawaki used to be weaker than me, but after he awakened Wood Release, his strength improved by leaps and bounds..."
Kushina looked dejected at the mention of Nawaki. He had never been a match for her before, but who could have known he would suddenly master the Wood Release Kekkei Genkai? Under Orochimaru's training, his strength had also improved rapidly. The last time they fought, Kushina had used three tails' worth of nine-tails chakra and still could not beat him.
Wood Release suppressed tailed beast chakra far too effectively. If Kushina failed to knock Nawaki down right away, she would only grow weaker as the fight went on. His regenerative abilities were also terrifying; even stabbing him through the heart did nothing.
"That was the Extremis Virus, a serum I brought that can strengthen the body. If you need it, I still have one dose here. Once I inject you with it, you'll be like Nawaki.
