Charys

Charys (カリス), formerly known as Ifrit (イフリート), was a Greater Elemental and the ruler of flames sealed within Shizu by Demon Lord Leon. He was defeated and captured by Rimuru Tempest but was released two years later and became the sole assistant to Veldora Tempest.

Appearance
Charys takes on the appearance of a horned, muscular humanoid with dark brown skin, golden eyes, claws, and a tail. As a result of Veldora's influence, his deep red hair turned a darker hue. His attire consists of just pants, leaving his upper body exposed.

Personality
Charys initially had an underdeveloped ego and possessed the disposition of a feral animal. Though he displayed some intelligence in using the environment to his advantage and employing trickery against his opponents, he mostly acted only on instinct and indiscriminately attacked anything he perceived as a threat to himself or Leon. This caused his host Shizu a great deal of anguish as it costed her valuable relationships, resulting in an irreconcilable wall forming between them.

After being imprisoned in Rimuru's Stomach, he had little to do but observe the outside world alongside Veldora who, not counting Great Sage, served as his only conversation partner. Through this, he gradually developed a sense of self. By watching Rimuru's daily life and taking in Veldora's wisdom, Charys began to sympathize with others and gained a keen understanding of the value of interpersonal relationships, causing him to realize why Shizu was always at odds with him and also feeling a sense of shame and regret over their fall out. By the time he was released from Rimuru's Stomach, he had become a calm and rational individual, reformed and fully loyal to Veldora and Rimuru.

Charys is characterized as a fast learner, as demonstrated when he nearly won against Veldora in a Shougi match very shortly after learning how to play the game. He is also cautious and extremely flexible in combat, holding his cool against superior opponents while employing various tactics against them and noting their effectiveness. His prudent nature has earned the caution and respect of Zalario.

Background
Charys used to be an inhabitant of the Elemental Realm, but was summoned to the Dwelling of Spirits and "stolen" by the "Platinum Devil" Leon Cromwell. After Shizue Izawa's summoning, he was sealed within her, turning her into a demonoid.

Trivia

 * "Ifrit" does not count as a name, but rather a name for his species (Greater Elemental of Fire). For this particular individual, he was nameless until named by Veldora, although he was constantly addressed as "Ifrit" until then.
 * He is one of the few individuals aware of Raphael's existence.
 * As shown in this rejected illustration for Dungeon Erosion, Illustrator and Character Designer Mitz Vah initially drew Charys with a female appearance. According to the writer Fuse, it was a result of a "misunderstanding". It got rejected in the final version on the grounds of potentially confusing the reader, not because the form was unrealistic or outside the character's capabilities. In the final version Charys is depicted in his masculine form.
