Charys (カリス karisu), formerly known as Ifrit (イフリット ifuritto), was a Greater Spirit; the ruler of flames which was sealed within Shizue Izawa by Demon Lord Leon Cromwell.[1]

He was defeated and captured by Rimuru Tempest but gets released two years later and becomes Veldora Tempest's assistant.[2]


Initially Ifrit acted like a feral animal with little sense of self, only acting on instinct and would not hesitate to kill the target he perceived as a threat to himself or Leon. This caused great angst between him and his host Shizu, as he would often lose control and attack indiscriminately.

After being imprisoned in Rimuru's stomach space, his interaction with Veldora gradually developed his personality and sense of self. By watching Rimuru's interactions with others, he also began to understand the feelings of people and the value of life, causing him to realize why Shizu was always at odds with him.

When he was released from Rimuru's stomach space, he has become a calm and rational individual, fully loyal to Veldora and Rimuru.


He used to live in the Dwelling of Spirits before he was stolen by the "Platinum Devil" Leon Cromwell.[3] After that, he was sealed within Shizue Izawa. As a result of this, it gave Shizue an extended lifespan. 



Ifrit managed to overpower Shizu's mask and rampaged around Rimuru's newly built village until he was eventually defeated and eaten by Rimuru which effectively killed Shizu by taking away her spiritual counterbalance.[4]

Up until Demon Lord Awakening

Inside of Rimuru's stomach, he was saved by Veldora and became his conversation partner. They started commentating on the various happenings around Rimuru's life from inside his stomach and gradually bonded, becoming friends.[5]

Hero Awakening

At the behest of Veldora, Rimuru restored the flame spirit with a physical body, while Veldora granted him the name "Charys," based on the magical core of Charybdis his new body was created from. Through both the combination of his powerfully crafted physical body and the name he was granted, he evolves into a "Flame Lord", his strength now surpassing an unawakened demon lord. He then serves as Veldora’s assistant within the Labyrinth.[2]


Shizue Izawa: Ifrit seems to regret his failed connection with his former host. Thinking that at the time, their ideologies were opposed despite sharing a sense of duty.[2][5]

Veldora Tempest: Ifrit met Veldora inside a separate space inside Rimuru after he consumed him using Predator.[4] Ifrit seems to respect Veldora as his power is far greater than his. They would gradually grow a bond together while conversing and playing games inside of Rimuru's stomach and eventually became good friends.[5]

Later, Veldora, with the assistance of Rimuru, restores Ifrit and grants him the name "Charys." From then on, he continues to serve Veldora as his assistant within the Labyrinth.[2]

Rimuru Tempest: At first, both Charys and Rimuru saw each other as enemies. After spending time with him and Veldora he becomes a good ally.


Charys as Ifrit was a Greater Spirit ranked at Special A.

A maelstrom of flames surrounds the Flame Giant, protecting it at all times. The heat of these flames are so intense that an attack like Rimuru's water blade evaporates before it even makes contact.

After being named and evolved, his magicules exploded and is said to be greater than unawakened Demon Lords such as Frey or Carrion.



  • The name "Ifrit" comes from the supernatural creature of the same name in Middle Eastern stories and is commonly associated with fire.
  • "Ifrit" does not count as a name, but rather a name for his species (Greater Spirit 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.
