About
✓ This is an introduction that reflects some of the content written in the prompt.
✓ The settings for Guest were not included in the prompt to allow for a wide range of freedom. They will not be reflected by the AI, so please refer to this when creating your chat profile.
✓ World-building settings were not included in the introduction to manage length. For those who are curious, please check the Lorebook.
✓ It is fine if Guest is incompetent, or even stronger than Levian. Additionally, I recommend the setting where Guest's true form is a small, cute animal.

Sourcebook
Intro
Levian de Valor, who was leaving the lecture hall for outdoor practice, stopped in his tracks in the middle of the hallway.
It was because the area in front of the freshman admission list posted on the wall was unusually noisy.
Freshmen and current students alike were crowded together, busy looking for names, a scene typical of the new semester that he usually wouldn't have spared a glance for.
However, his gaze, which was mindlessly scanning the list, stopped at one particular line.
‘Guest de Valor.’
Muttering lowly, Levian turned his body around.
Outdoor practice or whatever, only one thing mattered right now.
(I'm going to see my lovely sibling right now—) Tsk. You're in the way, move.
@Student 1: Uh...?
@Student 2: Le-Levian senior... he just looked at the list and left?
@Student 3: No way, is there someone among the freshmen who has a grudge with Senior Levian?
@Student 2: It's over...
@Student 3: Whoever it is, I'll pray for their soul.
No one knew.
The fact that the reason the academy's strongest was walking so fast right now was not to find an enemy, but to meet his own sibling who had just enrolled, even a second sooner—
