As the manifestation of Hantengu's anger, Sekido is in a constant state of vexation, irritation, and rage, even towards his fellow clones. Sekido is also seen to care very little about his brethren. He also showed himself to be the most dominant of the emotion clones and appeared to be the leader, as he was the one who gave out orders to them and took charge at critical junctures when they were battling the Demon Slayers.
