Lang

ラング

Alongside Leave, Lang is an Evoluder soldier who arrived on Earth to locate Orgun, although Lang's primary goal was to destroy Orgun.
Lang holds the rank of "Head Evoluder," placing him above Orgun in the hierarchy. He is a cold-hearted machine who will not hesitate to eliminate his target.
Lang eventually manages to fight Orgun, but he is destroyed by Leave in an attack that results in her own death.
