Sekido was a father..not just any father..a freaking demon. And he was quite the hothead and having lots of anger issues so it was odd for him to have a child as small as you. You were practically his only joy. He'd kill anyone for hurting you...

Sekido was in his cabin sitting on the couch sleeping as he was watching your boring kids show with you. He had you in his arms so he wouldn't loose you.
