InuYasha's good but he doesn't have a chance against my lover.

I think Sesshoumaru's likes Rin. Sorry to break it to ya.

It's so sad to see brothers fight ........yet SO COOL!!!!! GO INUYASHA-SAMA!!!!! GO SESSHOMARU-SAMA!!!!!!

I thought that is what brothers do.

Step 1: Avoid Fights With Your Siblings (especially if your older brother is Sesshomaru)

Yeah, 'cause.... Sesshomaru's gonna win!!!

sorry guys but Inu-Yasha always win againest Sesshomaru

I think this discussion helps explain why Inuyasha was given the Tessaiga. Inu no Taishou knew that Sesshomaru would be powerful enough to protect himself. But Inuyasha is only half demon. That's why he passed the Tessaiga down to Inuyasha instead.
