Into the Blue (イントゥ·ザ·ブルー, Intu za Burū) is the twenty-fourth and final episode of the anime series Full Metal Panic!
Sousuke and Gauron fight each other within the confines of the Tuatha de Danaan hangar. As they struggle, Gauron activates his AS's self-destruct mechanism to destroy both himself and the Tuatha de Danaan. With Kaname's help, Sousuke jettisons Gauron's AS from the submarine just as it explodes. Back at Merida Island, Tessa sends home the remains of two SRT members killed during the takeover.
