Misa Ilioroagu

One of Anos's classmates and a member of the academy's white-uniformed students. Being a half-spirit and half-demon with a demonic father and a spirit mother, she belongs to the "Unification Faction," which advocates for reforming the current situation in Dilheid, where beings who are demons but do not fully inherit the blood of the founder are socially deemed as "mixed-blood" and placed in a lower status. She is active within the academy under the guise of Anos's fan club named "Anos Fan Union."

Because she is a half-spirit and half-demon mix of a spirit and a demon, Misa can use a spirit magic spell called ＜Rain Spirit Mist Dissipation (Fuska)＞ that allows her to transform herself into rain. From this, Anos speculated that Misa might have a connection with Linion, the great water spirit, who specializes in ＜Rain Spirit Mist Dissipation (Fuska)＞.

Ray and Misa have been attracted to each other since the Demon Sword Tournament, and they became lovers before the interschool competition with the Hero Academy when Misa received a clamshell accessory from Ray.

Her true identity is the daughter of Shin Reglia, the right-hand man of the Demon Lord, and Leno, the great spirit, making her a half-spirit, half-demon bearing the false legend of the Tyrannical Demon Lord Avos Dilhevia.

The rumors and legends of the Tyrannical Demon Lord spread by Canon were well-known among humans and demons, so unlike Ray's mother, Misa isn't suffering from spirit disease. When Nousgalia's plan is enacted, Misa awakens as the true form of the false Tyrannical Demon Lord Avos Dilhevia and confronts Anos's group to break the seal of the Destructive Sun, but Ray divides her into Misa and Avos Dilhevia. Later, as a cost for awakening the god of destruction by Nousgalia's hands, Avos Dilhevia is destroyed. Afterwards, the source divided by Evanmana, the Spirit God Human Sword, two thousand years ago following an order from Anos, continues to spread rumors and legends, fulfilling the conditions for reincarnation and resulting in Misa being reborn as a good and pure spirit after being destroyed once.

Initially awakened as the true form, Avos Dilhevia and Misa as demons had separate personalities and opposed each other, but with the reincarnation of the true form, Avos Dilhevia, the consciousness integrated. However, it doesn't mean the personality of Avos Dilhevia disappeared; when the true form surfaces, it switches to the character of Avos Dilhevia. As Misa, she is an active and strong-willed girl, and as Avos Dilhevia, she has long black hair with queen-like dignified speech and behavior befitting the Tyrannical Demon Lord.
