Young Levius has lost a lot in the war. His revolutionist father is dead, and he lost an arm trying to protect his mother, who is comatose. Now his arm has been replaced by a metal prosthetic, and his Uncle Zacks has taken him in. The traumatized Levius soon begins to take an interest in mechanical boxing, and his uncle helps him get involved in the brutal sport.

Levius was originally published in IKKI magazine. The story of the series continues now to Ultra Jump magazine, and it is known as Levius/est.
