Danny coughed as the smoke from the jutsu washed over him. When it finally cleared, he stood tall and looked around. He found himself in a room that seemed to be decorated in an ancient Japanese style. The walls were made of rice-paper, and the floor was made of wood. There were a couple of sliding doors on one end of the room, and at the other end there was a large desk that sat in front of a window. The window occupied the majority of one wall. The hokage let go of Danny's arm and crossed the room, and sat behind the desk.
"Welcome to the Village Hidden in the Leaves," he began. "This is the hometown of the three genin that were sent to help you fight Zabuza, the rogue ninja from the Village Hidden in the Mist. It's also where you'll receive ninja training."
"So…am I going to be a full-fledged ninja?" Danny asked.
"That's our goal. Of course, there are many levels of shinobi. The first is genin, ninja trainees. One level up from that is chunin, and above that there are jonin, elite ninja warriors. You're going to train to achieve the level of genin."
"Okay…and who's going to teach me?" The hokage grinned.
"Send them in," he called. One of the sliding doors slid open, and four people were standing on the other side, three of them familiar to Danny.
"Danny! It's great to see you again!" Naruto shouted as he ran into the room and gave Danny a high-five.
"You too," Danny replied.
"Naruto will make sure that you achieve the level of physical fitness needed to become a ninja," the hokage informed him. "Sakura will teach you all about ninja ways, and the various types of jutsu. When you're ready, Sasuke will spar with you in order to teach you how to apply those skills in a battle situation." Sasuke and Sakura each walked into the room and stood slightly behind Naruto.
The fourth person, the one Danny didn't recognize, brought up the rear. He was wearing a blue uniform that had a red spiral over the shoulder. Over top of this was a green vest that had multiple pockets. The man's neck and the lower part of his face were completely obscured by a black balaclava that clung to his skin. He had messy silver hair that slightly resembled Danny's when in ghost form, and his headband was worn crookedly so that it covered his left eye.
"This is Kakashi sensei," Sakura explained as she followed Danny's gaze. "He's our teacher."
"Wait…I thought you already graduated ninja academy."
"We did, but we're still only trainees."
"Kakashi is a jonin," the hokage said. "He is going to administer your final exam."
"Great to meet you!" Kakashi said, and gave Danny a thumbs-up.
"Wow, this is really awesome," Danny said to no one in particular. "Just one question, though. What exactly is this sharingan that Vlad was able to use?"
"It's a jutsu that allows a ninja to analyze every move made by an opponent and copy it down to the slightest detail," Kakashi explained. Just then, the hokage tossed a small bag to Danny, who caught it.
"Some money," he explained. "You can't train wearing those clothes; you won't be able to move. Before you start your training, go into town and buy some new clothes." Danny shrugged as he pocketed the bag.
"Is there anything else I need to know?"
"Just how to find Naruto's house; you'll be staying with him. Otherwise, you're free to go." Kakashi and the three genin turned tail and left the room, and Danny followed. They exited they were in and Danny gasped. Outside was a huge village. The cobblestone streets were lined with shops, where shopkeepers were busy taking inventory of their wares and describing them to passersby. Further out, there were multiple white buildings that were many stories high. The buildings all had ropes strung from one building to another, and everything from laundry to Chinese lanterns hung down from the ropes.
"This place is amazing," Danny said weakly.
"Come on, let's get you some clothes," Sakura said. The five of them entered the busy streets and it wasn't long before they reached places selling clothing.
Two agonizingly long hours of trying on clothes later, Danny approached Naruto's house clad in sturdy blue sandals similar to the ones his genin friends all wore, beige shorts, and a high-collared white T-shirt. Over his shoulder he carried a bag containing several green-and-gray skintight undershirts that he would wear underneath the white one. He also had on white armpads that covered his arm from an inch below the elbow to an inch above the wrist.
"Well, I thought that went rather well," Sakura commented.
"No way! He looks too much like Sasuke!" Naruto complained.
"So?" Sakura countered.
"Please, stop bickering!" Kakashi said. Somehow, he managed to get the two to stop quarreling without raising his voice much. "What's important is that Danny is able to move around; not how he looks. Function over fashion, after all." By this time they had reached the place where Naruto lived. The setting sun cast long shadows that extended out of sight.
"Tomorrow morning we'll meet in the courtyard of the academy," Sakura said.
"If he's able to wake up tomorrow morning," Naruto said, then cracked his knuckles evilly. Danny gulped.
"Don't beat him up too hard, Naruto," Kakashi warned. "He is our guest, after all."
"What he is," Naruto replied, "is stick-thin. I'll get this guy into shape before long. Broken in half counts as a shape, right?" Danny was forcibly reminded of the last time someone had been assigned to help him get in better physical shape. He had passed his presidential fitness test, sure, but he had a feeling that to make it as a ninja he'd have to surpass the physical prowess of a sixty-year-old president.
"See you guys tomorrow," Danny said, then he and Naruto went into the building. They climbed the stairs and reached Naruto's suite, and entered via sliding door.
"You can have the bed," Naruto said.
"Are you sure? It's your house; I don't mind sleeping on the floor."
"Nope. This is part of your training." Danny shrugged and reclined on the bed. In a flash, Naruto had withdrawn a huge leather belt from out of nowhere and belted Danny's ankles to the bed.
"What the heck is this?" Danny asked angrily.
"Ten thousand sit-ups. Now."
"What? Are you insane?"
"I did this everyday while I was at the academy. Come on, I'll do them with you." Naruto lay down on the floor next to the bed. Danny groaned, and he and Naruto began his ninja training.
