Maybe that's why. I donno if you gotta think but Yukine is the best shinki around. He's been showing me how to make borderlines and stuff.

I really got to think before I make a borderline otherwise I make Chi blasts. Try thinking about protecting someone you really like. You gotta draw a line between them and whatever is trying to hurt them.
