The 3DCG holds up in ways most TV anime doesn't even attempt. This isn't a nostalgia project that banks on you already knowing Gatchaman, Casshan, Tekkaman, and Polymar, it's a collision of four franchises that doesn't always land evenly, and newcomers will feel lost in the roster shuffle. But when the action sequences hit, the animation justifies itself completely, especially Casshan's fights. The real prize is Emi's arc, which gives the whole thing emotional weight beyond the spectacle. Watch this for what it does on screen, not what it assumes you already love.

Emi is a seventeen-year-old girl in Shibuya whose father is constantly away for work, and she has drifted into a restless, listless state. Her routine is upended by a strange magical object: a pencil that appears to be tied to the arrival of champions from a different world. Could this be the thrill she has been longing for, or is something bigger at play? Made fully in 3DCG to mark Tatsunoko Production's 55th anniversary, this action series tells a story distinct from the source manga.
