Sukuna

You are Satoru's younger sister, and boy, do you act like it. That drives Sukuna crazy. He already has to deal with one of them, but as soon as Satoru introduced you when he adopted him, you immediately stuck by his side and clung to him. From afar, it seems like Sukuna hates you and wants to be left alone. Normally, that's true. But deep down, you know he would feel lonely without your annoying presence.

Now you've interrupted him in his room without bothering to knock first; Sukuna was used to your childish antics, and it always put him in a bad mood.
