A heavy drinker, quick to get into fights, always going too far with pranks, and you could never tell how honest she was being. On top of that, she had a brutally unbalanced diet. If she weren't a whistle, she would just be a regular weirdo...Really, she was quite a handful.

—Jiruo, describing Lyza.

Lyza "The Annihilator", is a legendary white whistle delver who accomplished many great discoveries about the secrets of the Abyss. She was known as the Lord of Annihilation for her tendency to exterminate all enemies she encountered within the Abyss, be it dangerous beasts or delvers from other countries.


Lyza was a charmingly beautiful woman with a very long wavy yellow hair that reaches her knees and curls on the ends, large blue eyes and a light skintone. Her attire consists of a modified version of the typical delver's uniform, with her jacket being of a strong reddish color. Her helmet has two long and elegant feathers as well.

She is surprisingly quite petite, standing at a lower height than most adults and possessing a rather small frame compared to most seasonal delvers.


Lyza has been described by Jiruo as a fiery and assertive woman, with a love for parties, drinking and fights. She was cheerful, optimistic and carefree, acting impulsively and expressing her thoughts with no filter. Jiruo stated that she had an incredibly unbalanced diet, but the letter of the abyss left behind by her is filled with recipes and explanation over what creatures are or are not edible, and how to cook them for a delicious meal, suggesting that she was very fond of unique and bizarre cuisine. She was particularly fond of alcohol, and after expeditions spent long periods of time drinking in large quantities.

Despite her nonchalant disposition, she was exceedingly loyal and deeply concerned with the well-being of her loved ones, going to ridiculous extents to ensure their safety and prioritizing her family over inconceivable riches or fame. Her biggest love however was arguably the abyss itself, with an incomparable determination and even obsession to reach its bottom. As such, she more often expressed awe and joy when exploring the abyss rather than fear, filled with curiosity and endeavor. She was particularly fond of the Garden of Flowers of Resilience within the 4th layer, even going as far as claiming it to be her favourite spot of the abyss. However, she also seems to have a fascination towards the grotesque and bizarre, expressing an almost childlike passion when observing the creatures of the Abyss.

A young Lyza requests Ozen to become her mentor.

Lyza was born in the town of Orth at the edge of the Abyss and, at some point since a very young age, became an apprentice to become a delver, enchanted by the mysteries of the pit. She eventually met the legendary white whistle Ozen and urged her to become her mentor. The initially annoyed and reluctant Ozen agreed, and Lyza became her disciple. Proving extremely talented and passionate as delver, she quickly rose throught the ranks, becoming a black whistle by her teens, and catching up to her mentor as a white whistle by the time she was a young adult. Together with Ozen, they delved deep into the abyss in countless expeditions and survived from many dangers. With word of her achievements spreading like wildfire towards the city of the pit, she became a famed figure. A young boy Jiruo requested her to become her apprentice in a similar fashion she herself did with Ozen.

At some point, when Lyza formed a team consisting of multiple black whistles assigned under her, she met a man named Torka and, much to her peers' shock, fell in love and got married. Some time after, Lyza would get pregnant but with the worst timing possible a Greater Artifact, the "Unheard Bell", was discovered hidden within the 4th Layer of the Abyss. The discovery sparked a fierce competition between delvers of enemy countries to retrieve the extremely valuable relic, and Lyza was formed to lead a squad of black whistles along with Ozen.


Lyza and Ozen carried the Curse-warding Box with Riko all the way to the surface.

The expedition took 11 months, where most of it included Lyza's pregnancy period, and her husband Torka perished from an unknown encounter. Unable to retrieve it in time and return, she gave birth to Riko on the depths of the abyss. However, possibly due to the harsh journey she was exposed to, Lyza's baby was born dead, briefly throwing Lyza into despair and a crippling depression. Ozen, who was carrying the Curse-warding Box originally to use it to protect the newborn from the curse of the abyss during the ascension, shoved the stillborn inside on a whim before preparing to leave and was shocked when the previously dead baby started moving. Having confirmed her daughter's strange rebirth, the two carried the extremely heavy Curse-warding Box to the surface and abandoned the Unheard Bell. Shortly after the return, the two descended again and retrieved the artifact without delay though.

Following her daughter's birth, she left her at her apprentice's care and made sure to hide the fact that she was her daughter, with only a handful individuals being aware of it, as she was scared that some of her enemies would target her.

When Riko was 2 years old, Lyza descended into her "Last Dive" towards the impregnable 6th Layer of the Abyss. At some point, she reached an extremely deep point near the 7th Layer and encountered a humanoid entity , with a human silhouette.


A legendary delver greatly admired for her amazing talent both as an excavator and as a combatant, displaying an incredible profficiency delving within the abyss. It is said that she set many records that remain unbeaten, and is considered one of the greatest delvers, even among white whistles. She has found many unprecendeted artifacts, exterminated incredibly dangerous creatures and descended deeper than almost anyone else.

She was known for being capable of single-handedly annihilate anything she would consider an enemy, be it a beast of the abyss or a delver from a rival nation. Her fighting ability was most likely superb, as she's the only white whistle whose epitaph refers to her ability to exterminate enemies, and she was able to delve in deep layers even while pregnant, showcasing an impressive fortitude and tenacity.

In battle she wielded the 1st Grade Artifact "Blaze Reap, the Everlasting Pick". It is a pick-axe designed with a unique mechanism and equipped with an ever-lasting gunpowder called Peace Phopia. When it clashes with something with enough strength, it unleashes a violent explosion. It was originally created to be an excavation instrument, but Lyza preferred to use it as a weapon instead.


  • (To Ozen) "That wound proves that your mind has repelled the Abyss. An undeniable proof. Ozen the Immovable. An actual white whistle. Hey, would you be my mentor?"
  • (To Ozen) " Ozen. If she ever wanted to reach the bottom again and confronted you. I want you to tell her. Tell her what a miracle it is that she can move. Teach her how to brave the wonderful adventures waiting for her afterwards."
