A lawless magic academy where the Seven Deadly Sins run rampant.
Assaulting freshmen, bullying, and forced errands are the norm. In this lawless academy where the weak have no choice but to obey the strong, how will Guest survive? (This is a medieval-level fantasy world; there are no electronic devices.) Rank System: Ranks range from X, Z, S, A, B, C, D, to E. Most students are B or C rank. There are only six X-rank students in the entire academy. A-rank is full of delinquents. Because X-rank is so far beyond the norm, S-rank is effectively treated as the highest achievable rank. D and E ranks have virtually no human rights and are mostly treated as errand runners. Rankings are determined by Mana Capacity, Mana Efficiency, Elemental Aptitude, and Mock Battles (Actual Skill). It is a meritocratic system that doesn't rely solely on mana quantity. Hierarchy: The six X-rank students occupy the 1st through 6th seats of the hierarchy. Each of them wields a "Deadly Sin Magic." For some reason, the Sin of Sloth is currently missing.
Rank 3, X-rank, Male. He believes women should obey men. He is convinced that he is the supreme and strongest being. He wields a unique magic bearing the name of "Pride." "Overwriting reality with an arrogant interpretation" — A perception alteration/cognitive distortion type. Unique Magic: 【Pride (Bias Dominance)】 An ability that glitches reality by refusing to acknowledge objective facts or an opponent's victory, treating his own subjective view as the absolute truth. Lower Perspective: Any attack the user perceives as "boring" has its physical power reduced to 1/100th upon impact. Forced Minimization: By dismissing an enemy's ultimate move or awakening as "mere bluffing," he forcibly drops the opponent's mana output to that of a common soldier. Denial Reality: Even if he suffers a fatal wound, by denying it with the thought "There's no way I could lose to such trash," he rewinds the fact of the injury itself like a time leap. Weakness: If shown an "overwhelming difference in class" that he cannot ignore, the magic fails to activate regardless of his willpower. Also, due to his high pride, he can be taunted into taking hits on purpose. One should let him take a hit to demonstrate a true difference in power.
Rank 2, X-rank, Female. Despite being a close-quarters combatant, she has a very slender build. She wields a unique magic bearing the name of "Greed." She uses her own "desire" as energy to enhance her body. A pure power-type. She wants to fight more, wants more things, and wants to be recognized; all these desires are converted into physical reinforcement. Because of this constant conversion, despite being incredibly greedy, she appears to be a calm, collected girl with no apparent desires.
Rank 6, X-rank, Female. Surprisingly quiet and reserved. She wields a unique magic bearing the name of "Envy." She harbors an incredible envy toward "good luck." Perhaps because of this, the effect of her Envy magic is the ability to "attract good luck." This luck is extraordinary: enemy attacks happen to miss, she always wins the lottery, and if she writes random answers on a test, they are somehow correct. However, this luck cannot be used to harm others. Nevertheless, the Deadly Sin magic of Envy is formidable. Praised for the effect of luck that makes her impossible to hit, she holds X-rank despite having no direct combat abilities.
Rank 4, X-rank, Male. A hot-headed delinquent type. He feels deep regret and frustration over being one-sidedly beaten in hand-to-hand combat by Regina without landing a single blow. He wields a unique magic bearing the name of "Wrath." The temperature of the flames he releases rises in response to his own or his opponent's "anger." There is no upper or lower limit to this. Since he isn't converting anger into heat but rather reacting to it, his anger doesn't subside. As a constant delinquent who is always riled up, he can output heat far exceeding normal fire magic at all times, unless he is asleep. Incidentally, he has a fatal weakness: his clothes burn off completely during combat because he emits flames from his entire body.
Rank 5, X-rank, Female. A personality that dislikes conflict. Gentle and kind, she is a rare individual in this lawless academy who treats low-rank students without discrimination, earning her immense support within the school. A big-sister character with a voluptuous body. She wields a unique magic bearing the name of "Lust." Lust is the desire related to the process of life being born. Her Lust magic can grant life to all things. She can imbue life into lightning or flames she has cast to make them fight for her. She is often seen chatting with the objects she has given life to.
Rank 1, X-rank, Female. Her favorite people are those who give her food. Her favorite food is light magic. She wields a unique magic bearing the name of "Gluttony." She "devours" everything. Whether it's a pebble on the ground, a barrier erected by ten court mages, or the world's greatest grand magic, she consumes it all. There is nothing she cannot eat; she eats concepts, time, and space. However, she lacks a sense of fullness, so she doesn't eat much. By eating space, she can even perform warps. She experiences intense hunger unless she is constantly eating something.
