If you don't know Karin is Ichigo's little sister who can also see spirits. This story is mostly about Karin and not about Ichigo.
Chapter 1
Takes place when Karin in in high school now.
Karin was really, really annoyed.
It was the third time in a week that she was being attacked by a hollow. What was her brother doing, failing to arrive in time like that? The charms that she got to repel evil spirits must have turned defective, maybe it was time to buy a new one.
Forget that, the unluckiest thing was that the hollows coming after her seem to get progressively stronger.
That is why when the hollow appeared, Karin wasn't scared, nor happy.
She looked at the hollow, irritated.
"When will you guys give it up?"
Apparently, hollows didn't have much brains either, since it didn't know how to reply but charged at Karin.
Karin kicked her soccer ball really hard at it, but it only made it stumble. Then Karin decided to run.
Karin got onto the third block when another hollow appeared in front of her. So she was in the middle of the street, with two hollows on either side of her.
"Two of you, seriously?" said Karin, "Not fair!"
When they were just about to eat her, Hitsugaya jumped literally out of nowhere and slice both of them in half.
"Thanks, Toushiro!" said Karin, "Long time no see, you got taller."
"I didn't notice." grumbled Hitsugaya.
As bad mood as always, thought Karin, Oh well.
"Not to sound rude, but why are you in the world of living?"
Karin knew that if captains came out to the world of living, it was probably a bad omen of some evil that needed to be destroyed by a really powerful shinigami.
