"Kagemane no jutsu!"
A few contortions of his hands, and shadows snake toward Inoichi's legs, stopping him in his tracks. Shikamaru walks backwards, careful careful, measuring each step. "Dude, watch where you're going," he says. "You almost crushed a baby turtle."
It's a struggle for Inoichi to crane his neck downward while still in the shadow's grip, so in kindness Shikamaru tilts his own head, pushing Inoichi's head forward. An infant turtle crawls out of the danger zone of his path. Shikamaru releases the jutsu. "Sorry about that," he says with a shrug. "You'd have probably cried if you stepped on it, so I thought I'd save you the trouble. And it's bad when turtles die, I guess."
"Yeah, thanks," says Inoichi. His face is flushed pink with the pain of possibly destroying a baby. He pushes the image of it broken from his mind, because that reminds him of missions past where human children died. He doesn't want to go there, not in front of Shikamaru, a newly-minted genin barely twelve years old. Inoichi says, "you can do that technique already? I'm impressed! Shikaku's been working you hard, huh?"
"Uh, yeah." Shikamaru shrugs, and drags his feet in the dirt. "It's really troublesome. I have to train with Asuma and then I have to train with him. I don't have time for anything else. But I guess you're going to tell me to work harder, right?" Inoichi nods, and Shikamaru rolls his eyes. "Just don't step on anymore turtles, okay? I'm gonna go train some more."
