ok as you know he is half demon. he does have a bother though named sesshomaru
(sha- shoe- mer- roo) they are enimies. unlike inyuasha sesshomaru is a full demon. he and inyuasha never get along. once inyuasha almost killed him but didnt have enough hate. how sewwt is inyuahsa?! he tries to act like he is all tough but yet he has a heart inside. he protects those he loves but doesnt admit it. he wears a necklace that has a spell on it. there is a girl names kagome, she is the only one who can make the spell active. suppose inyuasha is ready to hurt some one, witch he would, and kagome didnt want him to, she can say SIT! and he gets slamed into the ground because of the necklace, lol. he cant take it off. inyuasha can also turn full demon when he is really mad witch is bad. he is also has a sword called the tetsuiga. there is alot more to come but i gtg! cya http://tbn0.google.com/images?q=tbn:-hDrm3o9KktA_M:http://webpages.charter.net/azrael1985/inuyasha-wallpaper-7.jpg
