I didn't put a credit on the ED of "Hen Semi", so some foreigners were wondering who made it. I was the storyboard artist and director, so I guess it must have been me. It's not beautiful to put the same names on the same page, so I left it off, but that seems to be the source of confusion. It's funny, so maybe I'll leave out the name next time, too..
