Sea Without Exit(2006)

Koji Namiki is a young pitcher who has shown great promise on the diamond by winning the National High School Basketball Championships. Shortly after entering college, however, Namiki's athletic career is called into question after he suffers a severe elbow injury. But despite a disheartening diagnosis, Namiki is determined to make a comeback. With a little help from his teammates it appears that he is getting back on track, too. Recently, he's even developed a new slow ball that he and his teammates have christened "the magic pitch". Fate can be a cruel mistress though, and when World War II breaks out Namiki the entire team join the navy and begin a training regiment specifically designed to prepare them for the ultimate darkness, an submarine attack method also known as "The Human Torpedo".
