Inuyasha he has dog ears people would watch him and go like this
Hahahhahah

True!

At first, I thought Sesshomaru would, but then, think again: He's very smart, and he knows the etiquettes of a noble already, so he'll have not-a-very-hard time then
lol I'd say Sessh lol He's got such a hot temper sometimes... if he came to the modern world I'm sure he'd start a war with military... he'd probably win 2!!! lol
I think Sesshie might be able to cope with a whole new, different world.
He knows how to adapt to changes (his missing arm!)
The only problem for him would be his rabid, female fans stalking him wherever he goes and harassing him non-stop.
Oh, and to answer the question, I think Inuyasha would have pretty hard time. ^^
He's always doing everything his own way and sticking to it.
Really? I thought that Inu would have the least prob dealing with modernity since he's been there so many times... and he's already been accepted by the people around him like Kagome's family and friends... hmm come to think of it... Jyaken would have a lotta trouble with modernity... since he doesn't look human at all lol
Yeah, everyone's gonna poke fun at Jaken and his greeness and dogs will mistaken him for meat. ^^
I think it's Sesshomaru. He's so quiet that I don't even know what's he thinking
Kagura is elimated, 'cause she looks SOOOOOO like a human woman plus that kimono makes her Japanese-like

B) :ph34r:
I say Sesshy is having troubles with humans sometimes (but a lot)
LOL I don't think humans would have trouble with him... look how many fans he has already!!!
Inuyasha by far. He's so rude and mean no one but Kagome could like him.
