Oscar - Endless Work

Now, the group comes to a factory place where all the workers work constantly. They build up parts and then take them down again, making their work eternal. Oscha attacks by making the workers build the machine completely which is a giant gold robot that looks like Oscha. The group fights, but cannot destroy it. Kaze summons Odin to pierce through its armor and it is destroyed. Oscha escapes. Kaze leaves the group on their own and Lu decides to leave as well with a tearful goodbye to the children.
