I personaly am fond of the idea that Ishin from the Royal Guards. It just makes sense for me and explains why he wears his haori on his shoulder like that, why Shinji didn't recognize his Reiatsu, why no one connects the name Kurosaki to any known Captains and why he and Ichigo are so powerful.

I also like the idea that Ishin is from the Shiba clan. Think about it, Ichigo and Kaien share the same looks, Ishin and Ganju share the same looks and Kukkaku and Karin share certain appearance and personality traits.

IT ALL FITS!!!!!!!
