Shia is a character from The Irresponsible Captain Tylor. She is a Raalgon captain who often partners up with Dom.
Shia is unwaveringly loyal to the Raalgon Empire. At first she underestimates Captain Tylor, but after being tricked by him, she starts to take him more seriously than most others. She can be rather narrow-minded at times and is very determined during missions. As shown in the OVA she is also very aware of her sexy appearance and uses her charm to her advantage.
She has a strong comradeship with Dom and will follow his every order. Even when she questions it, she will still follow through. She doesn't seem to quite understand his friendship with Tylor.
Contrast to Ru Baraba Dom, she is rather brutal and rude in nature. Her nature revealed when she wants to destroy Harumi Nakagawa because she thinks Android has no use for emotion. She's rude to Captain Tylor when she kicks him after his surrender.
According to Dom's evaluation, she is short-sighted and has much more to learn. It's apparent when none of her strategy against Captain Tylor works if it is not for Captain Dom's strategy.
In light novel, her personality is giddy. Her family is Kuroun Has who is privateer pirate and used by Holy Raalgon Empire as Intel for generation.
