Ep. 4: Kaito Exploits Union Support and Regulatory Loopholes to Save A-TEC
Aired on July 25, 2015

After most students depart, Kaito leverages a labor union to aid the remaining group, only to discover they are exploiting his name for political gain. The union promotes him to Assistant Chief to sever ties, leaving him abandoned. However, five additional students return to A-TEC, inspired by the group's resilience. They identify a regulatory loophole that permits Kaito to utilize his executive promotion to secure necessary funds. This financial solution ensures the department can continue operating despite the union's withdrawal of support. The narrative highlights the struggle against institutional manipulation and the determination of the few who remain committed to their shared cause.
