Haruno Fuji (Fiancee)
Tetsuo is an inventor developing a personal alarm to protect people from assailants. Many people do not believe in him until his alarm was bought for 100,000 dollars. When Tetsuo informs his girlfriend of the sale, she questions if it is worth that much, and wonders why a toy company bought Tetsuo's invention. Tetsuo is more concerned with his new-found fortune finally convincing Haruno's brother Astronaut Fuji that he is worthy of dating his sister. When Fuji returns from space, He and his friend Astronaut Glenn invite Tetsuo and Haruno to lunch and Tetsuo tells them of the sale, but counter to Tetsuo's belief Fuji still thinks little of him. Tetsuo then takes Haruno's suspicions seriously and follows the man who bought his invention to a house near lake Myojin, but when Tetsuo tried to get in, the door mat came out from under him and he fell down a long chute into a cell. he remains there for some time before Astronaut Glenn is brought in as well. Tetsuo had already checked the cell by that time, and had determined that the cell was inescapable. Shortly after explaining this to Glenn, Tetsuo finds a note that had fallen from the astronaut's pocket that detailed how their Xilien captors were weakened by certain sounds. This prompts Tetsuo to try using his alarm system against them. This method proves successful and the two escape and give the device to the military to play on mass-broadcast to eliminate the Xilien threat.
