|“||Even though you are abysmally inferior to us, sometimes you cast spells that go beyond our expectations. Humans truly are intriguing.||”|
Megicula has a pair of curved, ram-like horns, a slender physical form, and long reaching fingers.
When Megicula takes control of Vanica's body, the hair on Vanica's right lightens in color, her right pupil becomes slit-like, and a dark-colored mark appears around her left eye. The mark is a circle with several dots along its length.
Megicula is shown to possess a highly inquisitive, curious, and intellectual interest in conducting various experiments with magic. The devil is genuinely delighted to learn of Secre Swallowtail's Arcane Stage Sealing Magic and its effectiveness in almost sealing the devil's own magic despite the immense power difference between them. The devil also expresses interest upon seeing the effects of its Curse Magic on Undine. Megicula's most favorite and interesting test subjects are humans due to them continuously surprising it.
Due to the devil's inquisitive nature, Megicula is highly unpredictable and whimsical. The devil viciously and cruelly experiments on any sentient beings, using its Curse-Warding Magic to see what kind of effects it would have on them. Once the devil's curious it is satiated, the devil immediately loses interest and kill them off without a second thought. This whimsical mindset is shared with the devil's current host, Vanica and thus gets along with her greatly.
Years later, Megicula, within Vanica, enters the Heart Kingdom, fights the Spirit Guardians, and curses Princess Lolopechka. The devil then returns to the Spade Kingdom. The Princess and Undine recruit Asta and some other Magic Knights to help save her and defeat the devil.Six months later, Megicula and Vanica return to the Heart Kingdom in order to kill Lolopechka. When Vanica draws on 70% of Megicula's power during her fight with Lolopechka, Megicula's Decaying World spell activates, so when Secre Swallowtail manages to seal Vanica, the arrays are weakened, allowing the devil to break them easily. Megicula takes partial control of Vanica's body, binds Secre, and destroys Lolopechka's Ludic Sanctuary, injuring Noelle Silva, Secre, and Lolopechka and cursing Undine. Megicula is delighted in successfully overcoming Arcane Magic and cursing a spirit. Lolopechka screams out in anguish over Undine and in pain from her curse, and Megicula apologizes for getting near the Princess and causing the curse to react. Vanica decides to kill Lolopechka when she sees that the Princess is unable to continue fighting. However, Noelle stands back up and refuses to allow that. Noelle charges through Vanica's attack and refuses to give up, which shocks Megicula and Vanica. Noelle then drives her lance through Vanica.
- Curse-Warding Magic: Megicula uses this magic attribute to create powerful curses. Megicula's power is even able to overcome arcane magic and to affect spirits.
- Immense Magic Power: As a devil, Megicula possesses tremendous magic power and is so strong that not even a Stage Zero-ranked mage of the Heart Kingdom can kill it. Lolopechka considers Megicula to be more powerful than Zagred, a devil with more mana than the strongest elves and Captain Class Magic Knights.
- "Even though you are abysmally inferior to us, sometimes you cast spells that go beyond our expectations. Humans truly are intriguing." 「私達に圧倒的に劣るというのに... 時に予測を超えた魔法を山してくる... やはり人間 (アナタたち) は興味深い Watashitachi ni attōteki ni otoru to iunoni... Toki ni yosoku o koeta mahō o dashitekuru... Yahari anata-tachi wa kyōmibukai」
- The mark that appears around Vanica's eye when Megicula takes over, resembles a marking that appears for users of the Mendelian Peas, a Eureka from Hungry Joker, Tabata's previous series.
