Bleach is not mine.

If Bleach mine, Karin will play larger role.

I change the template a bit for all chapter. Sorry for the alert.

CHAPTER 1

Self-Defence against Hollows

'Somebody better explain the fucking spiritual thing to me.' Karin enters Urahara's Shop.

Urahara welcomes Karin. "Welcome to Urahara's Shop. How can I help you?"

Karin is always straight to the point. "Explain what happened during last months to me. I tried to close my eyes about my brother and my father being Shinigamis, but with entire Karakura Town being involved and my brother become gloomy, I can no longer remain ignorant."

Urahara closes his fan. He owes a lot to Ichigo, and so is the entire world. "What do you mean with the Shinigamis? Why you are not asking your family, then?"

Karin snorts. "Please, Goat-chin always plays dumb. Ichi-nii become so gloomy after the whole town incident and it seems that he can't see ghosts anymore. Anyway, it's easier for us to not telling Yuzu about these spiritual accidents by not explaining to each other. That's why you are my choice."

Urahara smiles. "But I'm nothing but a handsome and humble shop owner."

Karin tries to kick Urahara. He dodges fast. 'She is definitely a Shiba. Scary.'

Karin smiles sweetly to him while readying herself for more kicks. "Don't give me that bullshit. I know you were talking with my father when he became a Shinigami few months ago. I tracked your presence to this shop."

Urahara sighs and opens the door to his living room. "Please come inside." He gestures to Karin. "Tessai-san, please make some tea for our guest!"

Karin enter the room and make herself comfortable. The tea comes fast, it seems that Tessai already prepared it since Karin entered the shop.

Urahara begins to explain. "Here is the story, Karin-san. Actually…"

After the lengthy explanation (not everything, of course)

.

Karin puts her tea cup on the table. "I wish to train my spiritual power, Urahara-san."

Urahara says, "But Isshin-san and Ichigo-san…"

Karin cuts his speech. "From what I saw in my brother case, spiritual power will grow stronger as the time passes. And I already met hollows saying I'm a tasty treat. I need to be able to fights them. Or they will dissect me later, along with people near me. There is nothing wrong in learning self-defence against hollows, right?"

Urahara rests his case. He resolves himself (along with Yoruichi and Tessai) to train another Kurosaki. "I see your point. We will begin your lesson next week. Don't worry, this lesson is free, I owe Ichigo-san a lot. As this is a self-defence class, there is no need for you to learn in fast pace like on Ichigo-san case. Please tell me your empty schedule." He gives Karin a blank paper and a pencil.

Karin write her spare times in the paper and give in to Urahara.

Urahara sees the time and says, "We start on Friday afternoon. It will be three times a week, along with Saturday and Sunday. Do you agree with it?"

Karin nods. "I'm fine with it. Do you think my sport is adequate for training?"

Urahara touches his hat. "Soccer is good for training your legs, but a whole body training is needed too. How does kendō sounds to you? It will help Zanjutsu too."

Karin starts to stand. "I'll start learning kendō, then. Thank you for everything, Urahara-san."

Urahara stands too. "Don't mind it, Karin-san. Be careful on your way out."

Next week, Friday afternoon

.

"I heard you are Ichigo's sister. Your name is Karin?" Yoruichi approaches Karin in her cat form when she enters Urahara's shop.

Karin turns around to see who is talking to her.

Yoruichi speaks again. "I'm down here. Is a talking cat that rare? You already sees the weirdness of this world, right?"

Karin shouts, "I might see them, but I don't believe in them! And I never met a talking cat before! Come to think about it, your reiatsu in not quite cat-like…"

Yoruichi starts to change her shape while saying, "A sharp one, aren't you?"

Karin's jaw drops. "You are a freaking shapeshifter! And a woman to boot!"

Yoruichi grins. "Hoping me to be a handsome man instead, Karin?"

Karin grins back. "Not at all. So, is it a ninja technique? It is pass from one generation to other instead?"

Yoruichi laughs. "Wanted to learn it, huh? You are okay with me being naked?"

Karin's blush comes late. "I will feel better to see you dressed, for sure. Will you be teaching me?"

Yoruichi comes to her wardrobe and get some clothes. "I can't teach you how to shapeshift, but I will teach you others. Your teacher already await in the training place." Yoruichi finished dressing and grabs Karin hand. "Come, I show you the way."

They make their way to the underground training place.

Karin is struck by the sight. "This place is so big! How can you made this? Cool!"

Urahara and Tessai are waiting for them.

Urahara says, "Welcome to my humble abode, Karin-san. Allow me to explain to you. You will learn Kidō from Tessai-san twice a week. Yoruichi-san will teach you Hakuda once a week. Zanjutsu will be learned as soon as you are halfway in mastering your Kidō skill. Hohō cannot be learn as one need to become a spirit to learn it. You are already fast on your feet from soccer, so it will be easy for you to learn it, but there is no need for you to become a Shinigami, right? This is only a self-defence class against hollows, after all."

Karin can't wait to begin her lesson, but something bugging her. "Why is the proportion of Kidō is bigger than others?"

Urahara opens his fan. "You know that we trained Ichigo-san in real hurry, right? We chose not to train him in Kidō as his control in reiatsu sucks and time was in gold during the training. Learning Kidō takes time, so we doubled it. And Kidō is easier to learn when your reiryoku is still growing. But rest assured. Most of your family members are generally good at Kidō, we think you can master it fast."

Karin raises one of her brow. "Most of my family members? Why you failed to mention them last time? Are you going to say that getting old makes you forgetful? Your brain freeze?"

Urahara's sweats dropped. Karin is too Kūkaku alike for his comfort. "Uh… I wish to tell you, but family story has to be told by family member, I think. Your father in this case. Umm… Forgive me?"

Yoruichi tries hard not to laughs. 'Can't wait to see Karin meets Kūkaku. It will be fun. Ganju will mop, though.'

Karin sighs. "That goat-chin of mine has too many skeletons in his closet. Damn him. If only he explain to us, I don't have to lie to Yuzu…"

Tessai clears his throat. "He has his reasons, Karin-dono. Now, are you ready for your first Kidō lesson?"

Karin give a small smile to Tessai. "I can't wait to start!" She realizes that Urahara has been giving minimum information only. "Sensei, what Kidō means?"

This happens after Ichigo lost his spiritual power. I think Karin will seek the answer from Kisuke, rather than other characters.

A little explanation of Japanese words I use here:

Reiatsu : Spiritual energy that people (and spirits) emit, either consciously or unconsciously.

Reiryoku : Spiritual energy reserve, can be hidden if one choose to do so.

Kidō : Spells that Shinigami can used, either to attack, defense, or heal.

Hakuda : Hand-to-hand combat, combination of martial arts.

Zanjutsu : Kendō, fighting styles with sword (mainly Zanpakutō).

Hohō : Shunpo, mostly about how to move fast, short distance or long distance.

I choose to use –san, and –dono instead of using Mr. or Miss because I feel comfortable that way. It's easier to show which character that has polite or casual way of speaking with that, too.

Sorry for the long author notes.
