Scream 'Inuyasha!' Grab Shippou and run away. Once in a blue moon, shoot your arrows. Miss. Look sexy and get someone to rescue you.
To fight like Miroku all you have to do is:
Look sexy and manly so girls will notice you. Wave around a big pole with little jingles on the end and attempt to kill people will that. Open up that wind tunnel in your right hand more than you should. And when Naraku's Saimyoushou show up and everything looks bad, rub some girl's ass. Doesn't matter who. Preferably Sango, however.

Wave around some big bone boomerang and cut crap in half. Ride around on your big, flaming cat demon. Scream, 'Hiraikotsu!' And then bitch-slap Miroku for rubbing your ass.

To fight like Sesshoumaru all you have to do is:
Look grumpy. Call people 'bastards', and call Inuyasha 'bastard scum' just for variety. Make your fingernails all weird and long and whip people with them. Try to steal Tetsusaiga, then get your own sword and decide Inuyasha isn't worth your time. Save Rin and Jaken and pretend you don't really care. And if someone REALLY pisses you off cough cough Inuyasha turn into a giant dog, roar, drool, and get your left arm cut off.
To fight like Kikyo all you have to do is:
Keep your face perfectly expressionless. Let your hair blow in the wind for no reason other than to make Inuyasha wildly jealous and make him wonder why he's with Kagome. Shoot your arrows. Actually hit the mark, unlike someone we know cough cough Kagome my god, I have this really awful cold cough cough Use priestess powers and blow stuff up. Look sexy. Pity yourself.

Get other people to fight for you. Or make imitations of yourself and get them to fight. Sit in a back room, wear a monkey suit, and laugh at people.

Run around really fast. Call Kagome your woman. Kick things. Run some more. Get your two cronies to follow you around. Call Inuyasha a bastard puppy dog. Look sexy in that miniskirt.
