Full Metal Panic!

In the 20th century, when the world structure was relatively stable, all major powers wanted to increase their military power to dominate the world. Whisper [whisperer] is a special human being who has special abilities since he was born, and he does not need to learn to know the high-tech means called black technology that surpassed the technology at that time for decades. In order to protect the stability of the world structure, the mysterious organization Mithril sent Sergeant Sagara and three others to protect a known Whisper, that is, Chidori Chana. Among them, Sergeant Sagara pretends to be a transfer student to follow up and protect him at any time. Because of his long-term life in the military, Sergeant Sagara, who has no common knowledge of ordinary high school students, made a lot of jokes in the school. Many horrible things happened during the school, such as the hijacking incident of the Soviet Union for the kidnapping of Chanel. Sosuke and Chidori also developed special feelings due to various events.
