After the triumphant sale of their anime at Comet-A, the Eizouken crew head to the hills to enjoy their first vacation together over the winter school break.

But they just can't give their creativity a rest, and roaming the mountain resort, Asakusa meets a pack of friendly but mysterious racoon dogs who inspire a plan for her grandest science fiction epic yet--Tanuki Eldorado! Meanwhile, Kanamori is meeting behind the scenes with the one person at Shibahama High who's as sharp an operator as herself--student council secretary Sowande Sakaki. Is she Eizouken's rival, their protector, or something else again...?
