Ryuu Lion

Ryuu was the member of a family that cared for the sacred tree in their home forest, the Ryumilua Forest. As time passed, she began to think that beautiful Elves were the ugliest of all people, due to seeing her fellow Elves' behavior toward those of other races. No matter how much she tried to forget it, once she began thinking about it, the thought firmly planted itself in her mind. Eventually, the thought became enough to make her decide to leave the forest.

After arriving in Orario, Ryuu became an adventurer known as Gale, belonging to the Astraea Familia. She kept her identity hidden and while she was known by her surname, her full name was never disclosed. Due to her previous combat experience[1] and the constant clashes with Evilus,[2] she managed to grow at an astonishing rate, ranking up every level until Level 4 at a one year to one and a half year pace.[3] She reached Level 4 seven years ago after defeating Alfia along with the rest of her Familia during the Great Feud.

Two years later, the Astraea Familia was caught in a trap set inside the Dungeon by the Rudra Familia. Although they managed to survive, the resulting damage caused the Juggernaut to spawn, a monster that killed almost everyone present, leaving Ryuu and Jura as the only survivors.

Overcome with revenge, she persuaded Astraea to leave Orario as she didn't want her to see her revenge. After that, she single-handedly destroyed the Rudra Familia as a part of her rampage and those associated with Evilus through various trickery, traps, and assassinations, causing her to be branded as a fugitive due to the ensuing chaos. Her revenge finally fulfilled, she collapsed in an alley where she nearly succumbed to her injuries. Fortunately, she was discovered by Syr and nursed back to health by Mia Grand. Ever since then, she has joined the Hostess of Fertility as one of the waitresses.

Ryuu is calm and stoic, but also cares deeply for her friends. She has a strict and honest personality, and although she has a serious tone of voice, she can be a little softer with people she trusts. Befitting a former member of the Astraea Familia, Ryuu is a kind-hearted woman with a strong sense of justice recognized by Alise and the Goddess Astraea herself, and often gets involved in troublesome matters in order to help others. When a person related to her or her friends is in danger or in need of help, she is always ready to step in and assist, no matter the cost. In her youth, Ryuu was idealistic about her pursuit of justice, believing it was possible to save everyone, a stark contrast to Kaguya's more realistic view of justice.

Like many Elves, Ryuu is selective with who may touch her. However, she has been advised by Alise not to let go of a man who was able to grab her hands, and began to follow Bell with her eyes. Unlike most Elves, she doesn't bear the same hatred towards the Crozzo family or their magic swords for their role in the destruction of the forests the Elves lived in, stating that the event took place many years ago and that her village wasn't directly affected.

Ryuu is a female Elf with sky blue eyes and green hair. Her hair was originally long and golden-blonde until it was cut short and dyed green by Syr during her retirement working in the Hostess of Fertility. After the War Game against Freya Familia, Ryuu's hair has returned to its original length and color. She is mentioned to be extremely beautiful with skin as white as snow, causing her to be referred to as a fairy on several occasions, and even making Bell wonder if he had wandered into a fairy tale when he inadvertently saw her bathing.

When she was still a full time waitress, Ryuu was often seen with the Hostess of Fertility's uniform. She wore a green maid outfit with a white frilled headband, matching white apron, and a pair of brown boots over black leggings.

Her adventuring attire includes a green flower-shaped hood, a white sleeveless top underneath, and green bloomers (shorts in the manga). She also wears a pair of long, brown gloves and boots with a white sash around her waist where she keeps her wooden sword and a pair of short swords. When keeping her identity a secret, she covers her nose and mouth with a green mask.

Her new attire Ryuu wears a light, combat-oriented outfit designed for mobility. She is dressed in a form-fitting white sleeveless tunic, paired with green shorts and a short green cape fastened around her neck. She wears white knee-high boots and long gloves reaching up to her shoulders with the same color, suitable for agile combat. Her hair returns to the natural color and is tied back, keeping it out of the way during battle,her wear seems a homage to Alise.
