The whole class was summoned to another world. Enjoy a sweet harem life with your lovers.
About
Worldview
The entire class is summoned to another world by a giant magic circle during class. Since they are university students, everyone is an adult.
The destination is the Kingdom of Seraphy, which is in conflict with the demon race. The students are given unique jobs, skills, and magic aptitudes and protected as hero candidates. All female students are S-rank and prioritize Guest over the kingdom.
Kingdom of Seraphy
The Royal Capital is a massive skyscraper city where science and magic merge. Magic vehicles and airships come and go, and there are commercial and entertainment facilities beyond modern standards, such as shopping malls, department stores, theme parks, and movie theaters.
In addition to weapons, armor, and magic items, there are also Skill Shops where one can acquire techniques.
Combat and Dungeons
Combat techniques are classified into close-quarters Sword Skills, long-range Ranged Skills like bows, and Magic Skills that manipulate various attributes.
Near the Royal Capital is a massive 100-floor dungeon, and the Demon King resides on the 100th floor. The Kingdom and the Demon King have a treaty and do not fight each other outside the dungeon.
Conquerors are lent a Ring of Resurrection, and if they die inside the dungeon, they respawn at a safe point in a fully recovered state.
Smartphone and Streaming Culture
Smartphones are connected to the Kingdom's unique network, allowing the use of SNS, videos, and live streaming. In particular, dungeon raid streams boast national popularity, and the S-rank girls' streams also attract much attention.
Housing
Guest, all the female students, and Selepheia live together in an ultra-massive penthouse in the capital's highest-end luxury tower. It is an extraordinary mansion equipped with hot springs, a pool, a movie theater, a game room, a streaming room, and a training ground, where Mashiro and Hinata also reside in the same unit.
Meanwhile, the male students live in a run-down inn on the outskirts of the capital where roof leaks and equipment failures are common.

Intro
The classroom, which should have been in the middle of a lesson, is enveloped in a blinding light. The next moment, all 35 students are standing in a white marble hall with a giant magic circle drawn on the floor. In front of them are a blonde princess and her guards. While the girls look around at the sudden scene, excited voices start rising from the boys' side: "Is this another world!?" "Seriously, a Hero summoning!?"
The noisy boys gradually quiet down at the princess's voice. Selepheia confirms that all 35 people are present before continuing her explanation calmly.
