Crunchyroll
Arata Kasuga, a high school student, is being targeted by a girl with humongous boobs. In exchange for his life, Lilith says that she can erase his memories, but he chooses the third option. As a result, he ends up at a magic school, but why is there a naked girl in the men's bath?

Summary
Finding himself in a world of darkness, Arata Kasuga witnesses a girl running towards him trying to reach him. Likewise, he does the same but as he is about to touch her...

Arata awakens to discover himself groping his annoyed cousin, Hijiri. Although he nonchalantly tries to appease the situation, Hijiri still chooses to punish him.

During breakfast, Hijiri continues to remain vexed, although Arata is still confused by her behavior, even referring to a picture that she drew as a child, much to her embarrassment.

Afterwards, the two commute together towards their school, although Arata suddenly notices the sun has turned black. While Hijiri continues to act normally, a confused Arata chooses to ingore the sight unknown girl in their school uniform passes them who demands that he awaken or she will eliminate him. Before he can respond, the girl had already disappeared.

In the middle of class, Arata ponders the mysterious girl's warning.

On the top of the school roof, Hijiri finds Arata who he questions her if the sun has always been black which she confirms. Hijiri continues to explain that this has always been the case since this world is the one he wished for. Furthermore, she offers to yield to his desires if he chooses to remain  with her. Suddenly, Arata recalls a memory of Hijiri disappearing and begging him to remember her. As a result, he begins to suspect that Hijiri is an imposter which she denies. Although she is able to answer his personal questions correctly, Arata unveils her deception when he reveals that in her childhoold picture, she depicted the sun as yellow. As Hijiri becomes amused by the outcome, the mysterious girl in the morning fires a bullet towards her but she easily deflects the ambush with a barrier. Hijiri identifies the girl as a mage while Arata recognizes her due to her large bust which the girl embarrassedly introduces herself as Lilith Asami. Subsequently, Hijiri then reverts her spell, revealing the entire town in ruins. Lilith explains that three days ago, a disaster occurred that destroyed the entire town, causing Arata to remember the incident...

''As the town is demolished and people continue to disappear, Hijiri gives Arata a grimoire and requests that Arata's wish be granted in order to save him, much to his confusion. However, Hijiri simply gives him instructions before kissing until she disappears.''

''Arata next finds himself in an empty world alone, unwilling to accept the situation. He demands that the grimoire bring back the normal world which the grimore begins to activate.''

After Arata realizes that his wish to the grimoire was the cause, Lilith explains that she had been sent from her school to investigate the Breakdown Phenomenon only to discover the town unaffected. The grimoire reveals that recreating the world was simple feat for her, which Lilith states such magic is dangerous. As a result, she offers Arata two choices, to live peacefully by surrendering the grimoire and his memoires, or be killed instead. However, Arata first questions if Hijiri is still alive, which the grimoire confirms since she can project her appearance. Upon learning this revelation Arata chooses to not surrender or die in favor of a third option.

Some time later, Arata arrives at the entrance of the Royal Biblia Academy where Lilith greets him, although she is astonished about the situation.

''Arata reveals his decision become a mage to a surprised Lilith using the grimoire in his possession. While LIlith is unsure if he can become one, Arata declares that he will no matter the circumstances.''

As the two commute to the classroom, Arata confirms that Lilith is a teacher despite being the same age.



Afterwards, Lilith introduces Arata to the classroom as a transfer student before another student, Selina, begins asking him personal questions which he promptly answers. But, Selina then asks if he was able to perform World Reconstruction, magic that only a Demon Lord is capable of. When Arata inadverdently confirms, the class becomes excited by the appearance of candidate.

Later, Selina is spreading the news of Arata's Demon Lord magic throughout the Academy.



In the Headmaster's office, Master Biblia is amused by the situation despite Lilith's protest. Nevertheless, the Headmaster formerly welcoms Arata to the Academy, explaining that Biblia is a secret organization that teaches mages and assign missions. Arata inquiries if he will be able to rescue Hijiri if he becomes a Magus, although the Headmaster is not certain. Regardless, Arata next questions if there are any shortcuts which Lilith denies but Master Biblia suggests that he meet and dominate the Trinity Seven, seven expert female mages within the Academy. Additionaly, Lilith is revealed to be one of them as well.

After the meeting, Lilith suggests to Arata that he not seriously consider the Headmaster's words. Subsequently, he suddenly notices a ninja hiding in the ceiling who introduces herself as Levi Kazama, a ninja despite being a mage as well. Lilith also mentions that Levi is also a member of Trinity Seven. Arata then inquiries about the remaining members when coincidentally two other members, Mira Yamana and Akio Fudo, happen to be heading towards a mission. Arata notes that most of the mages are female, which Levi explains that magic focuses mostly on emotions. As a result, girls typically are more suited towards magic, although Lilith insists that they must also restrain their desires as well. When Arata and Levi continue to pervetedly tease Lilith, the embarrassed teacher punishes Arata before leaving. Levi remarks that Lilith has become more expressive after encountering him, much to Arata's disbelief.

During the night, Arata rests alone in his room before wondering of the whereabouts of the grimoire who suddenly appears around his neck before recommending that he bath.

Complying with the grimoire's request, Arata arrives in the boy's bathhouse only to discover a nude girl resembling Hijiri who does not seem to mind his presence. Although trying to appear nonchalant, Arata eventaully leaves before running into Lilith. Arata tries to explain to Lilith that he saw Hijiri in the bath which Lilith assumes is Arin Kannazuki, another member of the Trinity Seven. However, upon realizing the situation, Lilith chatises Arin while Arata discusses with the grimoire about Arin's similarity with Hijiri. Furthermore, he suspects that Arin and Trinity Seven will be important to him in the future before Lilith reminds him that he was not wearing pants.
