Strait Jacket (OAV)

Le Chemin, the ending theme song of episode 2, was the breakout hit song of the French pop group Kyo from their second album that shares the same title. Le Chemin is French for The Way. The surmise that the group Kyo has an interest in things Japanese given the title of the group is correct; the group took their name from the main character, Kyo Kusanagi, of the SNK video game King of Fighters.

Some of the demons in this anime are parodies of real life ideas. For example, the spider demon squishes a human up against the wall as his first victim, when usually humans are known to squish spiders and other unwanted bugs. Also later, the only demon we see Isaac fight and defeat is a demon who's head is transparent. So you can see it's brain, which fires a laser beam when it talks about his light being "brilliant". This clearly is a spoof on the concept of having a "bright idea".

While the song “Le Chemin” by the group Kyo is credited for Strait Jacket’s ending theme, there is another song of the group Kyo that may be uncredited for its use in Strait Jacket. In Episode 3, in the scenes where the character Rachel is talking to her co-worker, then next where there’s a shot of a radio lying in the middle of a room, and then next where the character Leiot is walking down a street and is placing a bottle of cognac on a windowsill, a sample of the song “Je Cours” by the group Kyo (also from their album Le Chemin) is playing.
