Third person pov

Laps. So far that's all Hollow had done. She darted around the room perimeter as fast as her little legs would take her. Itachi and Hidan stood off to the side, watching as she ran around and around. She'd been doing it for an hour, and neither one of them could quite figure out why she wasn't tired yet. Surely it wasn't Meatball Kyle, who continued to hype her up from his place on her shoulder.

"Show this fucking floor who's boss!" His tiny body boomed. "Run on it! Step on it! Own the floor, Hollow!"

"H-Hai." She stuttered nervously, speeding up. She felt sweaty and hot, but not too tired. She had to assume it was because of Hikari. Her energy coursed through her, warm and very encouraging. It pushed her onward. She didn't see any reason to stop. Mr. Itachi-san had, after all, instructed her until she could run no more.

"You didn't tell me she had this much energy." Itachi's voice was cold and toneless just as it usually was. Hidan scoffed at him, shaking his head. Itachi was so stuck up, he almost wished they'd chosen someone else to train her. 

"You say that like I fucking knew." He spat, rolling his eyes. 

"How much energy does she have saved up in there? She's so small, I thought she'd be done already." Sasodai's brow furrowed with thought as Hollow continued to race around the room. She was sweaty, but she wasn't losing her breath or anything of that sort. She even seemed a little bewildered as to what the point of running in circles was, but she'd never been one to question.

"She does have a goddess in her." Midori said in a smart tone. "She's basically a queen at this point."

"All women are, dear." Sasodai patted her back. Midori puffed out her chest like a proud mama bird as Hollow sprinted past them. It was like she got faster every five minutes, and all because of that weird hamster perched on her shoulder. It kept telling her to go faster, and so she did. She would never say no, not even to a puny rodent.

"Should we stop her? I really don't think this is going to help her much." Yahiko scratched the back of his neck. "Isn't she supposed to bring about world peace or something?"

"Yeah. That's the plan, anyway." Shisui shrugged.

"Solid." Yahiko muttered sarcastically, earning a snort from Sasodai. Nagato's complete in utter faith in Hollow's non-existent plan to achieve world peace was mildly terrifying. He trusted a little, innocent girl to save the world as they knew it. She wasn't ready for that! How would she even begin to do something like that?

"Hey, Hollow! Come over here!" Shisui called, gaining her attention. Just as she always did when someone told her to do something, she obeyed, beginning to shuffle across the room towards him. Itachi raised his eyebrows and Hidan sighed, muttering about those "damn ghosts" and how they always ruined everything.

"She doesn't look tired." Itachi speculated.

"The little shit isn't. It's those dead bastards again. They're always lurking around." Hidan muttered grumpily. He didn't have anything against the ghosts, he just hated them. He didn't like the idea that he could be being watching and not know it. That someone, a person, could be drifting behind him and watching every mood he made.

"We're going to help you learn something else. Well, I am. These losers are just going to watch as I transform into the badass you're supposed to become!" Shisui clapped his hands together. Hollow nodded. Meatball Kyle didn't know what was happening, but he didn't doubt it had something to do with ghosts. 

Shisui led Hollow to the center of the room. The three ghosts were curious to see what he'd do, watching as he told Hollow something, his hands on her shoulders. She nodded up at him, and he gave a thumbs up. She seemed delighted, her eyes shining as Shisui drifted a few feet away from her. 

"Just copy what I do." Shisui instructed kindly, smiling. He then sunk into a pose that was clearly the beginning of a kata. Hollow gazed at him, her eyes scanning his form before she sunk into the exact same one. Shisui straightened so he could see if she needed any adjusting. Sure enough, she did.

Itachi's eyes widened when he saw Hollow sink into a familiar form. It was the beginning of the Uchiha's secret fighting style. The taijutsu their clan had designed. Shisui was the one teaching her. 

"Say, since you're her sensei now, do you want to give the brat the talk? She's that damn age and all. For periods." Hidan waved a hand in the general direction of the girl.

"What?" Itachi's eyebrows shot up.

"You know what I mean. Someone's gotta explain that shit." Hidan shrugged carelessly. Itachi stared at him blankly. "You know! Tell her about splurgin' the nurge. The old in and out. Adult naptime. Bam-bam in the ham-ham. The classic bedroom rodeo!" Hidan said, raising a fist. Itachi's face remained blank. "You know, sex and stuff!"

"No." 

"Dammit-"
