Strange nightmares have been keeping Heero Yuy awake at nights and he doesn’t know what they mean, or what has triggered them. Then a strange man appears who seems to know Heero very well. Who is this person? Why are they so happy to see him? What’s all this about magic? Who is Harry Potter – and why do they think he has something to do with his disappearance?

A desperate need spurs Harry to summon new friends in a cry for help that can only be answered by the Gundam boys.
