Stella

Stella (ステラ) is a Dragonewt and a member of the Dragon Faithful who worships Milim Nava. She came to Tempest under the orders to check out the city that grabbed the Demon Lord's interests. After tasting Tempest's food, her goal is to learn how to cook and serve her dishes to Milim. She is one of the main protagonists in the spin-off Trinity in Tempest, alongside Phos and Nemu.

Appearance
Stella is a young girl characterized by her striking blue hair, which she ties into thin twintails, and her matching blue eyes. She typically adorns herself in blue attire, akin to the clothing worn by other members of the Dragon Faithful, a group devoted to the worship of the Demon Lord Milim. Additionally, she often wears a hairband as a part of her ensemble.

While Stella possesses a humanoid form, she has the ability to partly transform into a draconic form, revealing her draconic features such as wings and horns. This transformation showcases her connection to the dragon lineage and emphasizes her affinity with the draconic nature.

Personality
As a follower of Milim, Stella is deeply devoted to the Demon Lord. Her personality reflects her loyalty, as she can be brash and direct in her interactions with others. She frequently expresses her admiration for Milim and holds her in high regard.

Despite her initial brashness, Stella exhibits a more diligent and humble side of her personality when it comes to learning culinary skills. She demonstrates a willingness to work hard and improve in this area.

In battle, Stella shares similarities with Middray, another member of the Dragon Faithful. She disapproves of dishonorable tactics and prefers a fair and honorable approach to combat. Stella remains composed and level-headed, even when faced with challenging situations. This is evident when she helped Phos regain her composure by offering guidance and reason in the face of anger.

Stella holds a strong aversion to the prejudiced attitudes of the soldiers from Falmuth, who harbor biases against monsters. This reveals her disdain for discrimination and highlights her compassionate nature.

Background
Stella hails from the Dragon Faithful, a devout group that reveres the Demon Lord Milim Nava. When news of Milim's planned visit to the city of Tempest reached the ears of the Dragon Faithful's Head Priest, he entrusted Stella with the important task of personally experiencing the city. Aware of Stella's unwavering dedication and desire to be in the presence of Milim, the head priest deemed her the ideal representative for their faith during Milim's visit.

This significant assignment presented Stella with a unique opportunity to deepen her connection with Milim and further strengthen her unwavering faith. As she embarked on her journey to Tempest, Stella carried with her the hopes and aspirations of the Dragon Faithful, eager to witness firsthand the presence of their revered Demon Lord and to partake in the festivities and revelations that awaited her.
