Full Metal Panic? Fumoffu (フルメタル・パニック? ふもっふ) is a spin-off season of Full Metal Panic! by Gonzo. The series takes place between the first and the second season.
Markedly different in tone to the first series, Fumoffu emphasizes the high school romantic comedy aspects of Full Metal Panic! with often crude humor and focuses on the romantic tension between Sousuke Sagara and Kaname Chidori. It frequently parodies itself and anime stereotypes. None of the mecha combat or political intrigue, which characterized much of the original Full Metal Panic!, can be seen in the series. The only reference to the mecha aspect of Full Metal Panic! is the Bonta-kun, which is one of the most prominent parodies in the anime.
''Full Metal Panic? Fumoffu'' was directed by Yasuhiro Takemoto and produced by Kyoto Animation, which replaced Gonzo as the series producer and became the first anime television show from this studio. The English version was produced by ADV Films. The original broadcast in Japan aired from August 25 to November 18, 2003. 12 half-hour episodes were created, but only 11 were broadcast on Japanese television. The missing episode was not broadcast because its plot dealt with kidnapping and was similar to a series of kidnappings that happened in real-life Japan shortly before the planned broadcast. However, the missing stories are featured on all DVD and Blu-ray releases.
