DON'T forget byakuya does have some weakness like high level spells even aizen lost to a spell when it all came to an end
also i this video didn't come up when i made my last post
But by byakuya only used kido spell under 81 He has never went higher and we shouldn't put a sealing spell on him for the very reason is he may not have it.
Now since byakuya probably doesn't have it he most uses he's other powers but i really don't think he will kill sesshomaru for the fact he can regenerate his body and heal him self from all kinds of damages.
No soul reaper can regenerate from what i've seen. But ichigo has done it every time he was beating into a near death moment.
I just wanted to state that sesshomaru's Tenseiga can kill a Cerberus the guardian of the underworld or hell he has also killed a Shinigami it kills anything thats not from This world So just about everyone in bleach would die in one move if he cuts them in one move. It's the sword of heaven
He doesn't have to look cool the creator of bleach based him off of sesshomaru plus all of their swords are based off of inuyasha's sword.
Sesshomaru is all was bad ass for 15 years.
Plus i think the Full medio would kill just about any bleach character even sesshomaru wouldn't be able to run from it. But sesshomaru can just break his way out of hell or his mom can always send a hell hound to him lol
I agree with you also a simple demon can put their heads back on if it's cut off but sesshomaru is just really powerful and that said he's durability level is really high
tHIS IS pointing to You finshed Now what makes you think he can take on this
Watch full video and you will see what he is dealing with note this isn't the strongest attack sesshomaru has
