Lena was born with her sister Amu in Vanity, they were both raised as warriors and trained during their childhood.
Lena's great challenge came when Galgear, the former prince of the darkworld who was awakened from his crystal prison, took over Vanity and kidnapped queen Valna. Lena formed part of the resistance leaded by Cham, and decided to go and save Valna, but Cham refuses to let her go, although she hears Yuuko's voice who convinces her and she let Lena go finally. Lena then tried to rescue Valna with the help of Amu, but Galgear himself stopped them. They were saved then by Asfal, Galgear's father, who wanted to help them and told them that the only way to stop Galgear was getting the Valis sword. Lena and her group made their way to Valhalla and talked with Yuuko, Lena then passed Yuuko's test and became the new Valis warrior. After this, they transported to the human world and beated Galgear's henchmen, Lena finally managed to defeat him, but her sister's life was taken in the process.
Lena was last seen visiting her sister's grave and walking away.
To the date, she is still the actual Valis warrior.
Lena is a determinated and habilidous warrior, she thinks about herself as born to be a justice warrior and is willing to follow that way no matter what.
She, although, doesn't like killing people or sacrificing the life of innocents. She seems to talk of more sometimes (such as when meeting Galgear for the first time).She also cares for her beloved ones, such as her sister Amu, and has a great admiration for Cham and Yuuko.
Lena shares most of her basic abilities with her predecessor, Yuuko, those are: jumping, sliding and using sword waves.
She can also increase her attack's strengh by leveling up.
She is skilled in the thunder spells, being one of the most powerfuls from the series.
In Super Valis IV, she can also run faster, use the multi-weapon system (like Yuuko did in the first games) and become invulnerable to any damage while using the Valis armor.
Lena only appeared in Valis IV (both versions) as the main protagonist and the new Valis warrior. She had to fight against the villain in turn from the game, Galgear.
