- Cattleya to Hajime

Cattleya was a ruthless, calm and collected woman. She has a realistic understanding when it came to war: knowing not to show mercy or an opening towards her enemies while not expecting them to do it in return. She berates Kouki for stopping himself from killing her when he had the chance, reminding him they are at war. When she was defeated Hajime, she didn't beg for her life and was ready to accept her fate.

During her attempt to convince the heroes to join the Demon's side, Cattleya showed a considerable level of tactical thinking, intelligence, and insight when negotiating and battling the "Heroes". As seen where she showed enough skill in psychological manipulation and warfare to manipulate the heroes into taking her offer using duress and intimidation. She effectively analyzed the true command structure of the group and deduced that Kouki was not the true leader, but Shizuku.

Cattleya was also capable of respecting other warriors when they surprised her, such as Meld Loggins. And according to Mikhail, Cattleya was kind, wise, and loyal. Despite her low opinion of hero and his group, she still followed her orders and invited them to the demon's side twice.

Chronology
By the time the heroes got to the 90th floor of the Great Orcus Labyrinth, Cattleya ambushed them along with an army of monsters that were given to her by their commander. She explained to them that her objective was to kill Hero and recruit the rest of the students to join the demons' side. When the hero blatantly rejected her offer and started attacking her, she and her group of monsters managed to outmatch the heroes where they were forced to flee to the 89th floor of the dungeon.

Cattleya then broke through to the 89th floor and continued her attack. As Kouki was prepared to resume their battle, he saw that her Monster were holding Knight Commander Meld Loggins as a human shield. This distracted him long enough for him to be knocked out by Cattleya's most powerful monster Ahatod. She renewed her offer to the students with the hopes that putting Kouki out of action would give them a better opportunity to consider it. While they were debating the choice, the injured Meld told them to prioritize their survival first and tried to kill Cattleya by sacrificing himself, but was thwarted after the energy from his attack was absorbed by one of her Monster, Absod. The demon then stabbed Meld through the torso and sent him falling to the ground. Kouki attempted one last effort to kill Cattleya by using his most powerful skill "Overload". He managed to overpower her, but hesitated to kill her when he heard her saying goodbye to her lover, and realized that his enemy was not just a mindless monster. Cattleya criticized Kouki for his simplemindedness and ordered Ahatod and her other Monster to kill everyone.

As Ahatod was about to kill Kaori and Shizuku, he was suddenly struck by a large metal stake that jetted through the ceiling and died instantly. To everyone's surprise, they were saved by Hajime Nagumo after Kousuke convinced him to rescue them. Hajime offered Cattleya one chance to escape, but in a fit of rage for the loss of her most powerful monster, she immediately ordered the rest of them to kill him. Hajime effortlessly dispatched her Monster and thwarted her attempt to escape. Despite the realization that she was practically good as dead, Cattleya refused Hajime's request to explain her plan and was shot in the legs as a result. Hajime followed up by correctly guessing that she intended to clear the true labyrinth and obtain the Ancient Magic that resided at the end. Cattleya was surprised by Hajime's guess and realized that he also must have been in possession of one of the Ancient Magics. She was prepared to die a warrior's death at his hands, but not before warning him that her lover would avenge her one day. As Hajime was about to kill her, Kouki tried to convince him to spare her life, but his plea fell on deaf ears as Hajime mercilessly shot her through the head.

After Hajime and the others left the labyrinth, other demons arrived to retrieve Cattleya's body. As they arrived, her body came under the possession of Eri Nakamura through her necromancy. Eri then used Cattleya's body as a way to communicate to the demons.

Skills

 * Earth Magic Affinity - It allows the user to use earth magic at a capable rate.

Spells/Attacks

 * Dark Gaol - A high-ranked earth spell that spreads a cloud of smoke that petrifies anything it touches. As long as any part of someone is hit by the petrification, it would slowly spread until they are completely frozen. The only way to stop it is to put up a barrier strong enough to repel it, or blow the smoke away before it touches anyone. However, only a high rank barrier would be able to hold it off. Furthermore, it requires an extremely powerful wind spell to be dislodged. “O great golden-eyed drake, slumbering deep beneath the earth, lord of all creation, your curse pierces through even the blackest darkness. Bring forth an everlasting seal of darkness, from which nothing escapes. Fear, despair, anguish, swallow it all and leave emptiness in your wake. All will fall before your stern visage. Destroy your enemies and return them to the earth — Dark Gaol!”
