Lefina is the captain of the Hiryu Kai/Custom the battleship that holds all the robots and she gives the orders to the pilots under her command, which varies since it's like the robots seems to bounce back from the Hiryu Custom and the Hagane.
Lefina is a very smart girl she's about 19 years old and she's already the captain of a ship. Lefina is also quite polite for being a pilot when giving the orders she says "please" XD
Lefina is ADORABLE too, at least to me she is, she's cute like a puppy or kitty. Oh, and that one person that I mentioned on my wallpaper of Elzam that fell for his Quattro Bajeena disguise... it was her. XD
Dedicated to Angel Zakuro as thanks for all the faves. :)
