Is Sesshomaru just like Byakuya in Bleach?

Answer 1

If you mean personality wise, no. They aren't super alike.

At first, one would think, "Oh, they are really alike. They're like, both aloof and all."

Well, not really.

At first glance, Sesshomaru often appears aloof and indifferent, and rarely shows any emotions other than slight annoyance or dissatisfaction.

Byakuya, on the other hand, he seems always serene and apathetic towards other people, even when he is actually deeply conflicted. He is also extremely calm, even in battle, and is very seldom surprised by even the most drastic of actions.

It really all changes, because they are both characters in which the creators go in depth with. The creators make them both arrogant and aristocratic and all, but later on, one reveals that he finds pride in his sister, the other finds compassion in himself while traveling with his young female companion.

They're both practically tsundere types. Both harsh, hostile, and cold, but later revealing their soft, mushy insides.

Oh. And on that note, there's actually a character in InuYasha named Byakuya too.
