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.
