Kakashi sat in his room, reading the new Icha, Icha series. Kakashi had just began to read a new chapter before his father Sakumo bounded into the room.

"Kakashi, got a new mission, gonna take a few months!" Before Kakashi could reply, Sakumo continued.

"And guess who I brought for company!" Kakashi felt his heart leap, "It can't be….."

"You're Eternal Rival!" Gai jumped into the room. Kakashi sighed. Sakumo had thought that Gai was the perfect rival for Kakashi. Gai had been pestering Kakashi for a fight for the past few months. Gai would appear anywhere, yes, including the bathroom. Kakashi didn't know how Gai could appear in the bathroom, but hey, he was desperate for a fight.

"Spar with me, Kakashi!" Gai shouted at the top of his lungs, pumping up his fist in excitement. Instead of answering Gai, Kakashi turned to Sakumo instead. He felt like shouting at Sakumo at the top of his lungs, but Gai was here, so he had be on his usual behavior.

"Bye, dad. Be careful." Kakashi said, ignoring Gai's comments about how good he was.

"Yeah, thanks Kakashi, stay safe." Sakumo turned and headed out the room. Kakashi was in agony, especially his ears.

"Spar, spar, spar!" Gai shouted. Kakashi sighed. He better be a good host, then.

"I'm showing you your room." Kakashi said glumly, heading out.

"But what about sparing?" Gai asked.

"No." Kakashi answered. He led Gai into the guest rooms, and closed the windows.

"Do you have weights?" Gai asked. "Like those that weigh like, 100 pounds?" Kakashi sighed. "What is he doing everyday? No, I don't want to know." Kakashi thought, grimly.

Kakashi sighed as Gai tried to do 500,000,000 push-ups and sit-ups. Gai has sweat trickling down his face, and some dripping down to the ground. "Eww!" Kakashi thought. He was very frustrated. All day, Gai had been asking him for stuff like: tennis balls, weights, mats for doing push-ups, and etc…. Kakashi was screaming inside. His brain felt like it was going to explode.

"Kakashi, what are we going to have for dinner? Can it be dumplings?!" Gai asked the furious Kakashi. "Just need to to sleep…." Kakashi thought. "NOOOOOO!" His mind forced him to stay awake. Kakashi sighed. He might as well make dumplings. "Long day." He thought.

Before he could walk to the kitchen, he heard Gai quietly scramble up from his mat. Kakashi's ANBU ninja instincts took over. He turned and grabbed his kunai from his pockets, and threw them at Gai as he attempted to jump and ambush Kakashi for a fight. Gai screamed and dodged.

"AHHH! Please don't kill me!" Gai screamed in fright. But Kakashi's ANBU instincts were still in control. He couldn't let Gai go unpunished. He grabbed to giant shurikens from a net stretched across the ceiling, and pinned Gai to the wall by aiming for his clothes.

"Why is your house so armed!" Gai shouted in absolute misery. Kakashi's ANBU instincts faded away.

"Just because." Kakashi said calmly, and went to retrieve the shurikens and the kunai. But just then, they heard a knock on the door. Kakashi ran to open it, it was Tenzo. He had a grave look on his face.

"Kakashi-san, it's your father, Sakumo-kun. Something's wrong."
