lol, many of the winter jackets and coats in fashion now (at least, recently in north america, not so new in hongkong and the rest of asia) have this kind of fluff/fake fur on the collar... perhaps sesshomaru was just really in style.
My fave is zeta or 08th ms team...
my least fave is V gundam and ZZ gundam...V was the only series i literally fell asleep watching it, ZZ just did injustice to the Zeta series.
