Arata Kasuga lived a normal life together with his cousin and childhood friend, Hijiri Kasuga, in a small town. However, everything changed on the day of the Black Sun. The Black Sun caused the Breakdown Phenomenon which destroyed the town where he lives and took Hijiri away. As Hijiri starts disappearing, she hangs a grimoire to his neck, asking it to protect Kasuga. Desperate on losing Hijiri and all of his other friends and family, Kasuga asks for his world to be good again, which leads to the grimoire artificially reconstructing his normal life, and making him forget the destruction of the city and Hijiri's disappearance. Lilith Asami, a mage, is sent to investigate the ruins and she finds the powerful spell in their stead. She makes Kasuga remember the actual events and consequently the spell is broken, not without the grimoire telling him that Hijiri is alive. Kasuga decides that his only option is to become a magus himself so he could rescue Hijiri and he thus joins the Royal Biblia Academy, a secret school for mages that deals with magical issues around the world. There he is introduced with the Trinity Seven, seven powerful female mages who are at the top of their respective fields (Lilith being one of them) who will help him in his goal of becoming a powerful magician and find the truth about Hijiri and the Black Sun. He soon finds out that another of the Trinity Seven, Arin, looks almost exactly like his missing cousin although she shows a completely different personality.

Arata Kasuga (春日 アラタ, Kasuga Arata)
Voiced by: Yoshimasa Hosoya (drama CD), Yoshitsugu Matsuoka (anime) (Japanese); Cameron Bautsch (English)Main protagonist of the series and the Demon Lord (魔王, Maō) of the Superbia archive, possessing the ability to nullify and copy magic. After a Breakdown Phenomenon destroys his hometown and causes his cousin Hijiri to disappear (but not before giving him her grimoire), Arata becomes determined to save her by becoming a magus and transferring to the Royal Biblia Academy where he fatefully meets the Trinity Seven. He usually speaks in somewhat a perverted manner and is calm in dealing with adversity (and often breaks the fourth wall). He is often referred to as the "Demon Lord Candidate" because only those of Demon Lord class mages are able to create worlds, but actually the world he created was merely a wish that he made with the grimoire to return the world the way it is. As a mage researches the one thing that is the farthest away from them, his thema is Impel (支配インペル, Control).

Hijiri Kasuga (春日 聖, Kasuga Hijiri)
Voiced by: Noriko Shitaya (drama CD), Ayaka Suwa (anime) (Japanese); Kira Vincent Davis (English)Disguised as Arata's cousin, she was a magus before she was engulfed by the Breakdown Phenomenon that Arata created. Later, she was 'reborn' to become the member of Iscariot, which seeks to destroy the cycle of the Demon Lord and the Trinity Seven, destroying the world and rebirth of the world. Although she becomes Arata's enemy, she still values Arata more highly than anything and wishes to make a world Arata could enjoy freely. She is referred to as the "Fallen Saint" by Anastasia-L during their encounter. She is a magician of the Ira (Anger) archive with the themas Ruina (Ruin or Destruction), Partum (Birth or Creation), and Analysis (Disassembly).

Trinity Seven

Lilith Asami (浅見 リリス, Asami Ririsu)
Voiced by: Ai Kayano (drama CD), Yumi Hara (anime) (Japanese); Allison Sumrall (English)She is the Trinity Seven of Luxuria (Lust) and her magic Outer Alchemic (錬金術アウター・アルケミック) materializes in the form of a gun which comes in two versions: a short pistol that she utilizes in close quarter combat and a long rifle that resembles an anti-tank gun which she uses at long range. Though she is of the same age as Arata and wears the same uniform as the rest of the female students of Royal Biblia Academy, she is actually a teacher of the academy. She is the first magus to appear in front of Arata during the Black Sun gravitational phenomenon incident in Arata's world where she was sent to investigate it. Such incident eventually led her to introducing him to the academy. She becomes one of his earliest allies and friend, watching and supporting him in any way, though at times she becomes an unwitting victim of his unintended and indirect perversion. As she is rather prudish, her thema is Abies (生命アビエス, Life) from the Luxuria (Lust) archive.
Arin Kannazuki (神無月 アリン, Kannazuki Arin)
Voiced by: Noriko Shitaya (drama CD), Aya Uchida (anime) (Japanese); Christina Stroup (English)She is the Trinity Seven of Ira (Anger) and user of Chaotic Rune magic, whose appearance is strikingly similar to Arata's childhood friend, Hijiri. She has a stoic personality where she has no reservation nor shame of doing what she wants in front of Arata. She was first seen naked in the boys' bathroom when Arata went in for a bath. She is also the Demon Lord's partner, becoming an early ally and later close friend to Arata. She claims herself to be Arata's wife as he is the Demon Lord candidate. As she only shows little emotion much less and can't even imagine destructive anger, her thema is Ruina (崩壊ルイーナ, Ruin or Destruction) from the Ira (Anger) Archive. Her magic Chaosic Rune (聖儀術カオシック・ルーン), allows her to put up barriers and create destruction.

As a user of Shamanic Spells (忍法術シャーマニック・スペル), she is considered to be one of world's top five fighters, becoming one of Arata's earliest allies. She is the only member of the Trinity Seven that hasn't been seen naked by Arata and her naked body is considered by Arata as his "final frontier". She often desires to fight Akio in a one on one combat but has never had the opportunity to do so. Due to being a ninja, who often work alone, she doesn't expect anything from others and thus her thema is Expectatio (期待エクスペクト, Expectation) from the Envidia (Envy) Archive.

Her thema is Justitia (Justice), which is part of the Superbia (Pride or hubris) archive, like Arata.

However, the Demon Lord from another world, Abyss Trinity, used the weapons of the Sky Library to destroy the city. Her mother had sufficient power to save only one person, and chose Akio, making her the only survivor of her home town. In the process she lost her faith, so that her thema is Fides (信仰フィデス, Faith), which is part of the Gula (Gluttony) archive. Her magic Mantra Enchant (真言術マントラ・エンチャント) gives her superior physical skills, which she uses for close combat.
