S01E31 Mikumo Osamu's Consciousness

Hyrein’s assault transforms Chika into a small, lifeless cube. Blaming himself for what happened, Osamu sinks into guilt—until the encouragement of his fellow Border agents reignites his resolve. Determined not to give up, he races toward Border Headquarters, hoping against hope that there’s still a way to bring Chika back.
