Thrown off the Moon Cell's Near Side with his memories gone, Hakuno Kishinami surfaces on the Far Side bound to Caster, the fox spirit Tamamo no Mae, inside the labyrinth the AI BB built out of the Holy Grail War. Tamamo's devotion is about as safe as the rivals hunting the pair. This manga runs the Fate/Extra CCC story down its Caster route, a different path through the same game than the other Fate/Extra CCC manga takes.
