Catherine Ruth and Hinako Okita, the captain of the First Platoon of Porton, had multiple fights with each other and finally decided to fight it out in War Time.
However, the Fourth Platoon wasn't allowed to compete in the War Time by Reina Mito because they couldn't use War Time for their own personal issues.
Catherine and her platoon mates (except Yuno) threatened Arata Sena to assist her to fight against Porton and Arata locked Haruki Izumo and Sakuya Hosono up in order to let the Fourth Platoon, except Yuno Kashima, compete in War Time.
When Porton and Jenock were about to fight, Rossius Union intercepted them, planning to take over the East End Bridge.
Before they could start their showdown after taking down Rossius, War Time was declared over and Catherine and Hinako bickered at each other through their CCM.
