In the Mairimashita! Iruma-kun Universe, or predominantly in the Demon World, Magic (魔術 Majutsu?) has existed since ancient times.
Three specific types of magic exist; Verbal, Non-Verbal, and Bloodline.
Verbal Magic (Rarity: ★)[]
For more information, see Verbal Magic
Verbal Magic (口頭魔術 Kōtō Majutsu?) is a common classification of magic that every demon use. With only a few phrases, they can summon or use magic with their mana.
Non-Verbal Magic (Rarity: ★★★)[]
For more information, see Non-Verbal Magic
Non-Verbal Magic (無口頭魔術 Mu Kōtō Majutsu?, or Mental Magic) is a very rare use of magic that only a few demons can utilize. For the demons to achieve such a level of Non-Verbal magic, they must undergo various training to strengthen their magic. Non-verbal spells are seemingly the same as verbal ones but done without the need to speak the incantation.
Bloodline Magic (Rarity: ★★★★★)[]
For more information, see Bloodline Magic
Bloodline Magic (家系魔術 Kakei Majutsu?, also called a Family Ability or Inherited Skill) is a special kind of magic that is unique in every specific demon family. However, like any other magic, they'll need to train to help strengthen this variety of magic.
