#4Clash! Union Battle

No factory, no money, no friends… A-TEC, led by Kaito, has its back against the wall.
But then, Kirishina Corp.'s labor union offers a helping hand to Kaito.
Kaito makes a passionate appeal to the union to protect A-TEC from management, and the union promises to throws its support behind A-TEC 100%.
But Mizuki remains troubled by a remark made by Nagisa: “The union is neither as squeaky-clean nor as righteous as you people think.”
