Ichigo's pov

"Oi," someone was hunched over me shouting at me, I opened my eyes to a gray sky with Rukia hunched over me. I was back in my body lying on my back hundreds of feet below the vortex that had sucked me in. The gray sky seemed weird, wasn't it sunny a moment ago. And what about the hollows. "Hey you okay?" Rukia asked.

"Yeah, I'm fine," I said sitting up.

"That was a close call. You fell hundreds of feet, I'm surprised your still breathing." Who are you and what have you done with Rukia, seriously she was being too nice. "What's your name?" the question stung me. Did she just ask me what my name was? This wasn't funny.

"That's not funny, you know me, we've been together for a while now." I said.

"I don't recall ever seeing you before," she said.

"I don't know what game you're playing at Rukia, but it's not funny," I scowled.

"H-how do you know my name?"

"What do you mean? I'm your friend we've been slaying hollows for months now. You live in my house." I strained.

"I don't know what you're talking about, I live in the Kurosaki house, someplace I know you're not." What was she playing at? Suddenly there was the ever familiar beeping of her Soul Pager and my badge, the sound of which alarmed her. I slammed the pass into my chest and took off into the air where hollows had begun to emerge. A small group easy, they're not even menos. I unsheathed Zangetsu.

"Getsuga Tensho!" In one shockwave I eliminated them all. When I returned to the ground I found Rukia's Zanpakuto at my throat.

"Where did you get that Zanpakuto?" she asked.

"What do you mean, it's mine I've had it for a while."

"Liar," she shouted, "That technique is belongs to the wielder of Zangetsu Karin Kurosaki."

"What the hell are you talking about Rukia?" Was this some kind of joke or maybe?

"She's been missing for several days now, where is she?" Rukia demanded. I broke away from her.

"It seems I won't be able to coerce you to answer with words, then I'll have to beat the answer out of you."

Shit, was she serious, I didn't want to hurt her. "You leave me no choice then. Bankai! Tensa Zangetsu!"

"What have you done with Karin?"

"What are you talking about, I left her with you when those hollows attacked." I stated.

"I don't know what you're talking about. Dance! Sode no Shirayuki!"

Wait, not knowing who I am, worrying about Karin, Zangetsu is her Zanpakuto, a strange vortex? The pieces were starting to come together. Rukia came charging at me I blocked with Zangetsu.

"You said you wanted to know who I am," Rukia looked at me in curiousity, "My name is Ichigo, Ichigo Kurosaki."

Rukia backed off immediately, "What did you say?"

"I said my name is Ichigo Kurosaki."

"Oh come on," she didn't seem to believe me, "There's no one in Karin's family with that name, especially not someone your age."

"Maybe not in this world," I said.

"Huh?" Rukia seemed interested by my words. I explained to her, almost in reverse what Karin had said the other day. I explained to her that in my world that I was Karin's older brother and that in Karin's place I had become the one Rukia transferred her powers to and rescued her. "Tell me something." She said, she had calmed down quite a bit, "Is Karin safe?"

I nodded, "she and her double are sharing the same body, last I saw her she was with your alternate self, I'm sure she'll be alright."

"Okay," Rukia lowered her weapon and then returned to her gigai, "I trust you Ichigo."

Rukia brought me to Urahara's shop. We figured the safest thing for me would be to get me out of her as fast as possible. Unlike Karin I didn't have an existence in this world so my involvement in it could be a bigger problem, not to mention that I had her Zanpakuto. I explained to this world's Urahara what I knew and about the Arrancar.

"I see, I'll see what I can do Ichigo-san," he said, "Of course it'll be more difficult now that you're here."

"Why's that?"

"Right now the two dimensions that connect your world with this world are in stable balance because there is only one Zangetsu in either one. Unless both dimensions can open simultaneously it'll be almost impossible to get you back or bring Karin here without re-upsetting the balance. Karin's existence in your world was already a hassle on the space-time continuum, since there were two Zangetsu's coexisting. Unless both of you swap your locations simultaneously, the world as we know it could explode." Rukia and I gulped. "If it's true that there's an Arrancar behind this dilemma then I would have to get my hands on its Zanpakuto in order to exploit its abilities. I'll try to work with the 12th Division from here and see if they can't locate it. In the meantime Ichigo you should try to make yourself comfortable here in this world because there's no telling how long you might possibly be here for."

"B-but Urahara-san where could he stay?" Rukia spoke out, "We can't leave him here knowing Renji the moment he finds out Ichigo's a Shinigami they'll fight and when that happens…"

"Relax," Urahara cut in, "If Ichigo is who he says he is then the safest place for him to be is in the comfort of his own home."

"B-but if he uses his real name," Rukia worried throwing her arm forward and to the side.

"That shouldn't be an issue," Urahara said, "There are many Kurosaki's in Japan, Masaki and Ishin won't jump to conclusions so quickly like you did, which you only did because of Ichigo's being a Shinigami."

At least I would get to stay in my own house, wait did he just mention my Mom's name. My mom, that's right she's alive in this world…she's alive. A broad smile crept across my face.

"Well what're we waiting for let's go Rukia." I said turning to leave.

Rukia's pov

"He's in awfully good spirits all of a sudden." I said.

"I guess that's a good thing, by the way, Rukia-chan,"

"Yes?"

"You should keep an eye on Ichigo-san, I want you both to transfer over to the high school. And most of all, it would be in your best interest to inform Arisawa-chan, Ishida-san and Yuzu-chan of the situation."

"Hai," I agreed, what he said made sense, "What about letting Ichigo fight?"

"I've seen Ichigo's type telling him not to go after hollows would be like telling wolves to stay away from fresh meat, even if it means exposing Zangetsu, but I guess so long as the issue doesn't run across Hitsugaya-taicho, Matsumoto-fukutaicho, Ikkaku, Yumichika, or Abarai-san we should be fine.

"Okay,"

"Oi, Rukia where are you?"

"You should go, just leave everything to me," Urahara reassured.

"Hai," I nodded.

Ichigo's pov

"Hey Rukia," I spoke out

"Yeah,"

"Why are you being so nice to me?" I wanted to know

"What's that supposed to mean?" she asked confused.

"Well you see, how should I explain this," I scratched my cheek, "In my world you and I don't necessarily get along all the time, in fact we practically want to kill each other half the time."

"Well maybe there's a reason my alternate self has to act like that toward you, but you're a pretty decent guy Ichigo-san, why should I act like a raving bitch towards you."

"Oh I see," did she add an honorific to the end of my name?

When Rukia and I finally got to "my" house she reached for the doorknob and spoke to me, "Just let me do the talking, I have a way with words."

"Yeah sure," I agreed.

"I'm home," Rukia announced walking in the door.

"Welcome home Rukia-chan," I recognized the voice that called from the kitchen, it was my mom's, "How's Karin?" Huh, Rukia didn't tell them that Karin was missing.

"Oh she's fine she's enjoying the overseas program she's attending very much." Huh, how could she get away with that one? Wait what was it Karin said?

Flashback

"Rukia transferred in as a student teacher for my class, but she was secretly there to keep an eye on me."

End flashback

"Rukia-chan!" I heard my dad's voice out of nowhere as he gave Rukia a bear hug, "Welcome home!"

"Thanks Mr. Kurosaki," Rukia coughed. Totally unfair I get attacked every time I walk in the door.

"Hm, who's this?"

"This is Ichigo, I found him lying unconscious out in the field." Rukia started putting on the sad face, "He didn't have anywhere to go and he has no place to live isn't that so sad?"

My dad started to tear up, "Poor kid, don't worry there's room enough under the Kurosaki house for you. It'll be nice to have another man around the house. I always wanted a son."

Rukia and I went upstairs leaving my dad being exactly as he had been when Rukia started to live with me in my world. Rukia knocked on Yuzu's door.

"Just a minute," Yuzu called from inside. She opened the door.

"Oh, Rukia and um…who's your friend?"

"This is Ichigo he's your um, older brother." Yuzu looked at Rukia confused.

"Rukia what are you doing Yuzu has nothing to do with this." I demanded to know.

"What do you mean? Yuzu's Karin's partner in all this" Rukia smirked.

"Rukia we're not supposed to tell people about that," Yuzu gasped.

"Huh, wait Yuzu knows about all this stuff?" I was really confused.

"Rukia what's going on?" Yuzu whined.

"Both of you be quiet for a minute," Rukia shouted, "Look let's start over, Yuzu there's something we need to discuss about Karin's whereabouts."

One explanation later…

"I see so Karin's in another dimension. Poor Karin," Yuzu tensed.

"Hey don't worry about it, she's with Rukia's other self so she'll be safe, besides if she could manage what I did, she'll be fine." I reassured her rubbing her shoulder.

"I guess so," Yuzu sighed still a feeling a little bit of angst. "So um Ichi…erm…"

"What's the matter?" I asked.

"I don't know how to refer to you, I mean supposedly you're my older brother, but I…"

"I understand if you want to call me Onii-chan like you do where I come from or something else I'm fine with that." I said.

"Oh thank you Onii-chan," Yuzu hugged me around the neck, that seemed to make her feel better. Suddenly Rukia's Soul Pager and my badge went off.

"Let's move," Rukia shoved open the window.

When we got to where the hollows were gathering, instinctively I unwrapped Zangetsu and attacked. Rukia soon followed. I watched as Yuzu transformed into a green hawk the size of her own bedroom. Too cool, I thought. As I hacked my way through hollow after hollow, a barrage of arrows came flying towards me getting rid of some hollows.

I noticed Uryu jumping off of a bike as someone else stopped it. "Who…?" I had no time to think as another hollow attacked.

Rukia's pov

"Uryu! Tatsuki-san!" I shouted running towards them. Tatsuki removed her bike helmet.

"Who's that guy?" Tatsuki asked pointing with her gloved hand.

"I'll explain later after we get rid of the hollows, but he's an ally."

"Fair enough," Uryu said and fired a barrage of arrows at all of the hollows.

Ichigo's pov

Since when did Uryu have a bow like that? I wondered, and what the hell is Tatsuki doing here? And why is she dressed like that? Tatsuki was dressed like a real punk. She was wearing a leather jacket, fingerless gloves, and a bandana around her head. I came down to the ground.

"So who is this?" Uryu asked.

"This is Ichigo Kurosaki," Rukia said patting me on the shoulder.

"Did you say Kurosaki," Uryu pushed in his glasses. Rukia and I gave Tatsuki and Uryu the rundown of who I was and what I was doing here.

"Is Karin safe?" Tatsuki asked me.

"Yeah she's perfectly fine, she's with Rukia's other self so I'm sure she'll be all right."

"That's good," Tatsuki seemed reassured that Karin would be fine.

"More importantly what happened to you? You're alternate self is nothing like this. You look like a gangster." Tatsuki decked me and it really hurt, the Tatsuki I knew never would've been able to throw such a hard punch, must be from the powers she has.

"You try being a goody two shoes with no friends around you for 6 years and see where you wind up?" she snapped. I heard the motorbike turn on "Find your own way back Uryu," she snapped and drove off. When I came to Yuzu's hands were around my face and glowing.

"Oh good your awake." She smiled

"You can heal?" I asked.

"Yuzu has an interesting ability called laying of the hands, it's part of her telekinetic abilities."

"I see," Sort of like Inoue's ability, my mind suddenly wandered, what did Tatsuki mean by no friends for six years, what about Inoue? Well tomorrow was a school day. I guess I'd find out tomorrow what was different at my school.

(A/N: And he will in time. From now on for the context of the story I'm going to call the dimension that Ichigo's from the Ichi-verse and the world that Fandom!Karin is from the Karin-verse. Also I'm going to say right now that because Yuzu's powers are nothing like Orihime's there's no reason for Aizen to kidnap her so Uryu had some time after obtaining his new weapon in order to meet up with the others. As to why he's able to help the others still let's just say Uryu is both good at finding loopholes and a rebellious individual. What did Tatsuki mean by having no friends, and where is the Orihime of the Karin-verse you'll have to wait and see).
