Naruto: Wooing Tsunade from Day One!

"Hm~"

"Nagato is unavailable, but Kakuzu should do."

"The three of you should barely be enough."

Kawakaze stroked his chin as he assessed the group, convinced there wouldn't be a problem.

Although the Four Red Yang Formation required four Kage-level shinobi to activate, Yahiko and the others had grown at an extraordinary pace over the years.

Leaving aside Nagato—the ultimate cheat—the rest were all geniuses. With better experiences and guidance, it was only natural they would reach Kage-level strength earlier than in the original timeline.

"Sensei, who are you looking down on?"

Konan pouted in defiance, her tone carrying a hint of playfulness that made her reaction quite cute.

"Haha, my mistake."

"I apologize."

Kawakaze laughed heartlessly, entirely ignoring Kakuzu's clear reluctance to be dragged into this.
