See if Urahara's open.

Being a little nervous that he'd have to explain himself to a furious Rukia, who probably wouldn't listen to a word he said, he decided that a trip to see Urahara would be a way to let her cool down a bit before he ventured home. He walked quietly, his hands in his pockets, his feet finding their way there automatically. Soon, the familiar store loomed in front of him, but it didn't look like anyone was in.
Ichigo stepped inside, and it seemed like the shop was indeed deserted. Urahara was famous for leaving his shop unattended. Ichigo was convinced that Urahara had put certain "wards" on the shop when he left it unattended so no one would just wander in there when no one was around. If he did put some sort of "ward" on the shop, it didn't seem to have any effect on Ichigo.
He took another step inside and said, "Anybody here?" Then he saw a shadow in a corner that seemed to move. He walked forward slowly to investigate the shadow and saw…nothing. "Huh. Must be seeing things. But with the day I've been having, that wouldn't surprise me at all." As he turned to go back toward the front of the store, he didn't make it two steps before something small and black tripped him. WHAM! Face down on the floor again.
"OOoohhh," Ichigo moaned as he rolled onto his back, feeling his face to see if he was bleeding from his nose. He sat up slowly and looked through tear filled eyes to see a black cat sitting primly, not far from him. To him, even through his tear filled eyes, it looked as if the cat was smiling at him.
"DAMMIT YORUICHI! WHAT THE HELL! DID YOU HAVE TO DO THAT?"
The cat seemed to chuckle and said, "You really should be more aware of your surroundings. Maybe you need some additional training on how to always be on your toes, and be able to sense when someone is watching you."
"Eh…I probably do. Where's Urahara anyway?"
"He left for a while, he decided to take the whole gang out for a dinner picnic. It was such a nice day that he thought it'd be nice for them all to get out for a little while."
"That was nice of him."
"Is there something I can help you with?"
"I guess not. I was just trying to waste some time."
"Rukia mad at you again?"
"How'd you guess?"
"You're too easy to figure out Ichigo." He thought for a minute and realized that she was right. "What do you say we head downstairs and I teach you some of that stealth training that we used in the Secret Mobile Corps?"
"Well if I'm going to give Rukia some time to cool off, I might as well. I could think of a lot worse people than you to waste time with Yoruichi."
"I'll take that as a compliment. Come on, let's go." The small black cat led the way to the back of the shop. Ichigo followed, opening a door that led to the cavernous basement that lurked below the shop. As he descended the stairs he recalled how not all that long ago, he'd spent DAYS there learning and perfecting his bankai, at the hands of Yoruichi herself.
The cat trotted effortlessly down the steps. Ichigo followed behind. Soon they were at the bottom of the enormous space that Ichigo knew well. Then he remembered that he didn't have Kon anywhere near him. "Uh, I don't have my mod soul nearby, but," Ichigo dug deep into his pocket and pulled out the badge that Ukitake had given him. He showed it to Yoruichi, "I got this from Ukitake."
"Ukitake gave you that? I didn't think they gave those out to anyone! I didn't think they were allowed to give those relics out!"
"He gave it to me before I came back to Karakura. I'm supposed to carry it with me, but it gets a little embarrassing when the thing starts shrieking like a siren yelling, "HOLLOW, HOLLOW," in the middle of the school day."
"I can see how that would be a bother. Sit down and let's get started."
"Sit down?"
"You'd rather assume your shinigami form and let your body fall?"
"Oh yeah, right, I've already had enough contact with the floor today. Good thinking Yoruichi." Ichigo sat down against a large rock outcropping, took out the badge and almost instantly, he emerged in his shinigami form as his body slumped backward against the rock. "All right," Ichigo said, "where do we start?"
Yoruichi walked out into the center of a wide open space. She said, "Follow me." Ichigo followed the small black cat. Once they entered the area, she said, "Close your eyes."
"Do I need my zanpakuto?"
"No. This is all about using your other senses and your spiritual energy to find your opponent. But with the problems you have with controlling your spiritual energy,"
"That's not my fault!"
"Concentrate Ichigo! I'm going to leave you here, and go out among the rocks around you. You just have to listen, concentrate, reach out with your spiritual energy and find me. But I won't make it easy for you."
"I didn't think you would. Go ahead then."
"All right. Count to ten, then find me. Start NOW!" Yoruichi disappeared and Ichigo was left to concentrate and try to find her.
The substitute soul reaper tried to focus. All he heard all around him was silence. He slowly turned, his feet making scuffing sounds on the rock below him that sounded booming in the silence of the cavern. He stopped, waited and listened. "I can't find her at all," he thought to himself. Then he tried to concentrate his spiritual energy and send it outward to see if he could feel her, feel anything other than the silence that seemed to be pressing into him.
He flung out his spiritual energy and felt it shape itself around rocks, then he felt almost a glimmer of something that didn't feel like rock, it was small and felt like a void in space to him. "Could that be her?" he thought as he turned his body to orient on that small dead space. He called, "I'm guessing you're right over there," he said as he pointed toward an outcropping that he couldn't see because his eyes were still closed.
"Nice job," Yoruichi said as she came out from behind the rock he was pointing toward. "How did you find me?"
Ichigo opened his eyes, "When I expanded my spiritual energy, there was this blank spot. I figured it was you cloaking your spiritual energy."
"You're right about that. But now I'm going to try moving. See if you can find me if I'm moving and silent."
Ichigo closed his eyes again and waited. Ten seconds later, he again tried the trick of expanding his spiritual energy. After a few moments he caught a flicker of emptiness, but then it was gone. Yoruichi, being so small in her cat form, moved quickly making it very difficult for him to find her. But as he watched for the small spots of blankness, he noticed a pattern that she was following – sort of a hexagonal pattern around her. Ichigo flash stepped sideways and intercepted her before she could reach her next destination.
"Gotcha," Ichigo said as he looked down on the small cat.
"Well done again Ichigo. You're getting the hang of it. But now, let's try something different."
"Like what?" Ichigo asked.
"Like, let's turn the tables. Let's see if you can suppress your spiritual energy and hide from ME." Then Yoruichi began to transform from her cat self to her shinigami form. And just like the time that Yoruichi transformed from a cat to human form when training Ichigo to achieve his bankai, when the transformation was complete, she stood before him completely naked.
Ichigo's eyes almost fell out of his head while one huge pulse emanated from what his eyes saw, directly to his brain and then downward in a hormonal spike that flooded him with testosterone. He quickly turned around and said, "PUT SOME CLOTHES ON YORUICHI! JEEZ!"
"Oh please Ichigo! What's wrong with my body?"
"There's NOTHING wrong with it, it's just that I don't want to look at it while you're all naked!" he said while he thought, "Because I want to KEEP looking at it, and you'll distract me!"
"What's your problem? It's JUST a body! I don't have any clothes down here to change into."
"Well then find some because I'm NOT playing hide and seek with you until you do!"
"Why not? I can find you with or without clothes on."
"I just don't want to accidentally grab anything I'm not supposed to," Ichigo knew that Yoruichi would probably kill him if he did grab any of her 'lady parts' while they were training, even if it was accidental.
"You're hiding from ME, not the other way around. Now GET MOVING!" Yoruichi demanded.
Ichigo held up his hands and said, "Wait a minute, I'm pretty sure I don't need any more practice today. Maybe I should come back another time when you've got some clothes on so we can do some more training?"
