-They both are tough and good fighters
-They're independent
-Kagome is always mean to Inu by 'sitting' him
-Kagome gets mad at the stupidest things
-Miroku always gropes other women
-They both know how the other feels about losing family and being alone.
-They both have over-sized weapons (okay thats not really a reason, but it's true)

also I hate hojo for no reason so don't ask me why I hate him. I only like Inu/Kag pairings if a) it includes them going into the present time and if they go to a beach or something like a vacation, like in the story A Summer's Vacation by sapphireshine or b) if it includes Kagome getting abused/raped and Inu-Yasha comes to save her. Like in Bonded by kiyoushi.
Ja ne!
