What Kay does

A melee burst dealer: Inferno Awakening transforms Kay for 10 seconds and ends with Burn to Ashes, up to 1920% of Attack on every enemy. Determination stacks twice for up to +48% Critical Hit Chance and +96% Critical Damage, and basic attacks during the transformation cut its cooldown by 3 seconds each.

A cheat-death passive also grants damage immunity at the brink of death, on a 50 to 60 second cooldown.

Profile

As a child, Princess Elizabeth of the Britannia Kingdom trained in swordsmanship alongside Kei, the eldest daughter of her swordsmanship master, Hector. Kei and Elizabeth built a deep friendship as they honed their swordsmanship skills together. Kei was 1-2 years older than Elizabeth, and her chest was larger.

One day, after finishing their training, the two girls were ambushed by goblins on their way back. The goblins captured Kei, tore her clothes, and attempted to assault her. In that moment of despair, Elizabeth unleashed a red light and incinerated the goblins in an instant. Later, Kei realized it was the blessing of the Red Dragon.

As time passed, Kei matched Elizabeth's martial skills but longed for the power of the Red Dragon. Frustrated by hitting a wall despite her training, Kei decided to run from the hometown. She wanted to be recognized by the Red Dragon and receive its blessing herself.

On an island in the east of the Britannia continent, Kei discovered a cave she believed to house the Red Dragon. However, upon breaking the seal, she awoke not the Red Dragon but the Flame Emperor, the lord of flames. In no time, that power possessed Kei, and she isolated herself on a deserted island to master it.

On the deserted island, Kei struggled to control the Flame Emperor's power. In the process, her body became even stronger, with her large chest becoming more firm as if to contain the Emperor's fiery energy. Eventually, Kei gained complete control over that power.

Years later, when Ethan and his party arrived in the Mercia Kingdom, Elizabeth and her companions were struggling at the Tiamat Human Experiment Facility. At that moment, Kei appeared. She unleashed the power of the Flame Emperor and rescued Elizabeth's struggling party.

"Elizabeth, long time no see," Kei said, appearing against a backdrop of flames.

"Kei? How are you here...?" Elizabeth asked in surprise.

Kei smiled and replied, "I set out longing for the power of the Red Dragon, but in the end, what I gained was the power of the Flame Emperor. Now I can control it completely."

Elizabeth felt the change in Kei and grew tense. "Kei, your power has grown immensely, but why do we have to fight?"

Kei answered with a gleam in her eyes, "I still want to be your equal. No, I want to surpass you. Elizabeth, duel with me. I want to be acknowledged for this power."

Elizabeth nodded, seeing Kei's resolve. "Alright, Kei. I'll accept your challenge."

Kei looked at Elizabeth with fiery eyes and said one last thing. "If I win this duel, you will acknowledge me and serve me as your master. Ready?"

Elizabeth raised her greatsword and replied, "Anytime."

The two faced each other with their swords drawn, beginning a fateful duel. The clash between Kei's Flame Emperor power and Elizabeth's Red Dragon blessing led to a battle that seemed to set the sky of the Mercia Kingdom ablaze.

Kay is a female Human. Her birthday is September 15, and she stands 174 cm tall. Kay is voiced by Bo-na Kim in Korean. Her hobby is drinking Tea.
