Radio Storm, Vol. 4 (manga)

Armed with the knowledge that he and Sak are not the destined partners he thought they were, Lima's actions become even more brash than before. With the academy still hiding their true intentions from the core user and his caller, Lima takes the next chance to escape from their grasp. But with the transmitter now broken, it's just a matter of time before Sak recognizes that his feelings for Lima were all false--an illusion meant to keep him in line as a weapon of war. Will Sak's previous passion for his caller win out over his feelings of betrayal?
