Humanity finds itself in a struggle when the sea level begins to rise to an unprecedented level in the year 2039. To make matters worse, powerful enemies resembling old wartime vessels called the Fleet of Fog roam the waters, severing communication and transit to various regions. Any attempt at retaliation ends in failure with humanity's current weaponry. Only Gunzou Chihaya stands a chance against the Fleet of Fog as captain of the friendly Fog I-401 submarine Iona. As a result, Gunzou and his crew, known as Blue Steel, are tasked with a critical delivery mission by the Japanese government: they must deliver humanity's last hope against the Fleet of Fog, the Vibration Torpedo Warhead, through hostile waters to the United States for mass production. Though involved in the unsavory conflict, Blue Steel strives for nothing more than a peaceful resolution to it. As Iona undertakes the current mission and tasks beyond it, the crew upholds their values even in the face of harsh situations.

For Kanade Amakusa, life as a high schooler should have been normal, and it would have been—if he wasn't living with the most ridiculous curse imaginable. "Absolute Choice," a system forced upon him by a self-proclaimed god, randomly presents a mental selection of actions that he must act out based on his choice. To add to his dilemma, it tends to occur in the most public of places, and his options never seem to deviate from the rude and crude in nature. As a result, the helpless boy stresses through each day, fumbling to repair his already tarnished reputation while desperately praying to avoid the next spontaneous episode of Absolute Choice. To his dismay, the one in charge is always one step ahead of him and proceeds to not-so-subtly "choice" him into the lives of several girls at his school. Just when Kanade's school life can't seem to be doomed any further, a decision that he reluctantly selects on the way home sends a beautiful girl crashing down from the sky, along with the promise of more hysterically hellish choices.
