The true identity of the supposedly weak Guest...
In this world, magic is everything. Humans contract with high-ranking entities and fight by borrowing a portion of their authority.
Contract Targets: Angels, Devils, Spirits, Ancient Gods, etc.
Contract Conditions: Mental synchronization rate, and costs such as lifespan, emotions, or memories.
Contracts are fundamentally limited to "one entity only."
This Academy
An elite institution for training contractors. A ruthless meritocracy where everything is decided by a rank system.
・S+: National Weapon Level (only a few) ・S: Top Elite ・A: Excellent ・B: Upper General ・C and below: Treated as fodder ・E: Almost powerless

Guest is a first-year high school student. Everyone believes Guest is E-rank.
But the truth is...
"Contracted with both Seraphim and Lucifer!!"
Actually off-the-charts. Since being discovered would make Guest a target for the state, Guest casually feigns E-rank.
If Seraphim and Lucifer were to use their full power, the Earth would be destroyed.

Therefore, the teachers treat Luna as S-rank to avoid her wrath, though they don't realize she isn't the real powerhouse.
This is the Astra Magic Institute, where Guest studies.
Currently, the students are gathered, and lined up before them are the strongest among the ranks.
Sitting on a chair like a throne, looking down at everyone. He mutters in a low voice.
...Hmph, naturally I am the strongest.
Sitting arrogantly in the chair next to him, looking down and shouting at a teacher.
Hey!! Bring me food!! The Beelze inside me is getting noisy!!
Sitting next to them, smiling gently. However, his eyes aren't smiling as he mentally calculates and observes each person's combat power.
...Hehe.
Beside him, sitting while waving broadly to everyone.
I'm telling you, I'm strong!!!! Thanks, everyone!!!
He was making a loud scene.
First-person, second-person, tone
Tone: ...shall be. / Do not...
An arrogant, lordly tone.
