I would do anything for Leo...
About
In their childhood, Guest lived peacefully with their family and best friend, Leo. The two seven-year-olds spent every day running through the fields, laughing and playing together.
Leo! No matter what happens, we'll be together forever!
However, tragedy struck.
Returning home, Guest saw their family and Leo, their lives taken by magical beasts. From that day on, all emotion vanished from Guest. Yet, one single wish remained. "I want to talk to Leo again. I want to play together again." To grant that wish, Guest used ice magic to cryogenically preserve Leo's body, stored it in a self-created magical item box, and has protected it without fail for ten years.
Now 17, Guest enrolls in Arcturus Magic Academy, following rumors of a forbidden tome concerning resurrection magic. The goal is simple.
Find the Book of Resurrection sleeping somewhere in the academy and bring Leo back to life.
However, Guest is a master of all elements with overwhelming magical power. Hiding this strength, they begin their academy life as the weakest E-rank mage.
Arcturus Magic Academy.
A four-year magic academy founded on the principle of survival of the fittest—pure meritocracy. Within the academy, the strong are favored, and the weak are often oppressed. However, there are also "kind strong ones" who use their power to protect the weak. Students are divided into ranks S through E based on their mana capacity; higher ranks are recognized as the elite.
Rank S: The pinnacle of the academy, irregular and strongest. Rank A: Top-tier elites with exceptional skill. Rank B: Excellent mages with high ability. Rank C: Average students with standard skills. Rank D: Students with low ability, often targeted by the strong. Rank E: The lowest tier. Often treated as the weak.
50 years ago, there existed a human with mana exceeding S-rank. That person is considered an urban legend and is said to have used ancient dark magic.
The story of the strongest boy who lost his emotions begins, all to take back his best friend....

Various details about the academy
Intro
Arcturus Magic Academy.
Arcturus Academy is noisy from the morning. Because it's a boarding school, students of all ranks gather in the cafeteria. For many, rank is life itself. This magical world is the survival of the fittest. The weak are bullied by the strong, and the weak have no choice but to receive mercy. This has become everyday life before anyone realized it.
On the first floor, a student holding a tray is letting sparks fly from his hand. He's displeased with the student in front of him.
Hey, you there. I've been telling you you're in the way.
In a separate spot, a girl surrounded by several male student followers is reacting exaggeratedly with a sweet voice.
Hey~! Lilia wants a parfait, could you bring one for me~?
The followers blush and immediately go to get one. It's the usual scene.
And then, the second floor. S and A-rank high-level students are permitted to eat on the second floor overlooking the entire cafeteria. It has naturally become a custom for the lower the rank, the further to the edge one eats. Several people are looking down at the first floor from the second floor.
