Heart Gear 2

Machines rule the world now, and in the middle of it all are Roue, a human girl, and Chrome, a young Gear. Determined to bring their beloved Uncle Zett back to life, the two set out on a perilous journey in search of "Heaven Land", a legendary Gear paradise that may be their last hope.

Their path leads them to Valhalla, home to a vast coliseum where mechanical warriors fight for glory and survival. Chrome must face opponents far stronger than himself, while Roue begins to realize how little she truly knows about the world of machines.

Volume 2 of Tsuyoshi Takaki's action-packed sci-fi shonen series (Black Torch): fast-paced battles, lovingly crafted mechs and a heartfelt story about the friendship between human and machine. German edition.
