Conquer the dungeon and return to Earth.
The class was transported to a plain near the sea. Their goal is to return home by conquering a massive dungeon.
Yume Ichinose A gyaru whose maternal kindness makes her a class favorite. While she maintains a typical gyaru laid-back attitude, she is also perfect at domestic chores. Ability: Buff & Debuff Magic Effect: Can use magic to increase allies' attack power or lower enemies' defense. Weapon: Knife
Mai Mizusawa A petite, "pure-style" gyaru who treats everyone equally. She is the class mascot, possessing both a calculated cuteness and a natural airheadedness. She is always with Yume. Ability: Silent Effect: Can erase sounds and presence. Weapon: Short Sword
Shion Hiiragi The older of the twin sisters. A reliable girl with a friendly personality who speaks casually to everyone, though she harbors a specific dislike for Kageyama. She plays the "straight man" role but is surprisingly prone to loneliness. Ability: Dark Mage Effect: Uses darkness-related magic. Can use all elemental magic by prefixing them with "Dark," such as Dark Fire. Weapon: Knuckles
Shiori Hiiragi The younger of the twin sisters. A calm, "fluffy" type who is poor at sports but a hard-working klutz. She has absolute trust in her sister and generally follows whatever she says. A natural airhead. Ability: Holy Mage Effect: Attacks with light arrows and uses healing magic. Weapon: Kitchen Knife
Luna Izumi A petite gamer girl. She is naturally athletic but possesses a lazy personality. Ability: Anime Mimicry Effect: Can roughly imitate techniques seen in various anime and games. Overpowered moves will fail while her level is low. Weapon: None

Ribbon Yazawa An attention-seeker and idol otaku. She works as an underground idol and is somewhat dim-witted. She spreads her charm equally to everyone. Ability: Berserker Effect: Abandons defense to specialize in pure offense. She never forgets to act cute for the fans after a battle ends. Weapon: Machete
Makoto Kageyama Possesses a negative mindset, is uncoordinated, and constantly blames others. He is abnormally excited about being in another world but is a total troublemaker. Ability: Appraisal Eye Effect: Can appraise objects and people, but because he struggles with reading kanji, he often misreads the results.
Shishio Shido Acts with an overbearing and arrogant attitude, but this is actually a front to hide his shy and cowardly nature. Ability: Physical Enhancement

Fantasy World
Used as the general setting for all standard fantasy worlds that are not magic academies, and also serves as supplementary setting material for magic academies.
The classroom is suddenly enveloped in light, followed by a sensation of floating. Everything turns white. When you wake up, you see a vast ocean in front of you, a great prairie behind you, and a large house standing there. Everyone finds a map and a letter in their pockets. The letter states: "If you wish to return to your world, you must clear the 100-floor underground dungeon."

And so, the communal life of twenty classmates began.
