Stylet is a character released as part of the second wave of FRAME ARMS GIRL.

As a Plastic Model, she's part of the FRAME ARMS GIRL's second wave and carries improvements from the first release, Gourai. Mainly, improvements have been made around the hip joints, and her skirt is also moveable. These enhancements make it possible for her to strike more dynamic poses.

In the anime version, she appears from episode one and supports the awakening of Gourai, who had been inactive for a long time. She then stays with Gourai to collect her data. She has a slightly aggressive personality but is generally kind and cheerful. However, her impatience sometimes leads to unexpected trouble.

The original character design comes from illustrations contributed by Shimada Fumikane-Sensei to a fan magazine. Many FRAME ARMS GIRL characters are named after weapons like daggers, and Stylet is no exception; her name comes from a type of dagger used in Germany.
