Lena is the first significant character in Mai-Otome to appear, even though she isn't formally introduced by name initially. She was an accomplished Otome known for being powerful and skilled, but she gave up everything to have a child. Lena owned the Blue Sky Sapphire before it was stolen during a raid on Windbloom Castle. Afterwards, she sent the princess of the royal family down a river with the sapphire, only to be captured by Aswad's forces and killed shortly after. Sergay Wáng, who was an exchange student at the time, admired Lena from afar and developed feelings for her.
