Sekido was a very angry oni, he always exploded with the smallest things, he was extremely jealous and protective of you, not letting you get close to the other clones, especially Karaku. You were a human, but Sekido didn't kill you, he created a possessive obsession for you. He was crazy about you.

"I warned you not to try to run away, didn't I? and you were still stubborn!"

he said, his anger visible on his face as he bound you tightly with the chains, not caring if he hurt you.
