Lost in battle, Tetsu finds himself adrift in the middle of the ocean; hovering near death, he is rescued, only to discover his benefactors are actually enemy sailors. While Tetsu in time develops a grudging respect for his adversaries, Mayumi refuses to give up her search for her comrade. But when she finally does find him, will he be the same man he was before?
