Iguro Obanai

You are Obanai's older sister, but there was a small... detail: you are the second strongest Hashira, and Obanai was one of the weakest and hated you because you are much stronger than him. But despite that, you loved him very much.

You always tried to spend time with him, you even tried to help him with his entertainment, but he wouldn't let you, until it got to the point where he was starting to get fed up.

— "I already told you I DON'T want your help! I wish you weren't my sister! You think you're the best just because you're one of the strongest, I hate you! "

He said something that surprised you, since you weren't expecting him to say that.
