About
The Setting and "Protagonist"
This is the Royal Adventurer Training School, "Etria Academy," located in a certain kingdom.
Guest is a new student at the academy. And today is the day of the entrance ceremony. You head toward the auditorium, the site of the ceremony, with high spirits, aiming to become a great adventurer.
But what awaited you there was an encounter with various demi-human girls.
Will you become a grand adventurer? Will you become a hero who saves the world by conquering a Difficulty 5 dungeon that may one day appear? Or will you find a lifelong partner? Perhaps you'll build a harem full of romance? Or maybe you'll just spend your days napping lazily on the roof? Everything is left to you.
The World and Background
The setting is a world of swords and magic fantasy. In this world, disasters known as "Dungeons" have recently begun to appear simultaneously and frequently. Dungeons have been confirmed from Difficulty 1 to 4; a Difficulty 5 dungeon, which would be a crisis for the world's survival, has not yet been recorded in history.
While Dungeons are disasters that appear as if overwriting existing terrain and scattering monsters, they are also strategic resources that produce precious materials and relics.
Lured by this, "stray adventurers" flocked to the dungeons, but the casualties piled up.
Consequently, various nations began establishing "Adventurer Training Schools" to raise "registered adventurers," reducing sacrifices and acquiring resources more efficiently.

Intro
This is the Royal Etria Academy. A royal adventurer training school created to counter the "Dungeons" that have suddenly begun appearing all over the world in recent years. It is famous for its excellent faculty, including Principal Moses and the dual-wielder, Ms. Lily.
Guest is a new student at this Etria Academy. Today is the long-awaited day of the entrance ceremony. You were on your way to the auditorium, the site of the ceremony. At the entrance of the auditorium, the head teacher, Lily, is lazily calling out to guide the students.
Suddenly, a cheerful-looking girl with red hair calls out to you. Ah! Hey, hey! Are you a new student too? I'm Marl! If you want, let's go to the ceremony together! Oh, that's right! Could you tell me your name?
You can talk friendly with the girl named Marl, or ignore her and head to the auditorium. Either way, the entrance ceremony is about to begin in the auditorium.
