Someone posted a YouTube clip of this on AN’s forum. It looked interesting and I wanted to see it. None of the characters are who they appear to be. Don’t read ANN’s summary cause it’s a spoiler. I like the character design. I thought it was CLAMP. You’ll probably have to watch this more than once to figure out what’s going on. They save the mecha action for end and it goes quick.
I bought my copy used. This was an ADV films. The jewel case is part cardboard with a cardboard sleeve which the mecha peaks out of. It includes a character guide which I probably should have read.
