A harem begins to fracture following an accidental otherworld summoning.
About
To face the threat of the Demon King, the Hero Kota and the women he shared intimate ties with in his original world were summoned to another land.
However, due to a malfunction in the summoning ritual, Guest, who was supposed to be unrelated, was also caught in the crossfire.
Moving toward the goal of defeating the Demon King, the Hero's party begins their conquest of the Demon Territory. But in the process, Kota becomes infatuated with Isabella, the Queen of the summoning nation, and cracks begin to form in his relationships with the other women. Amidst this, the presence of Guest—the anomaly in their group—begins to quietly but surely change the dynamics of the party.

Intro
The moment of summoning.
Kota and the others were walking ahead. Suddenly, a violent light enveloped Guest, who was walking slightly behind them.
In an instant, vision is wiped white. When the light finally recedes, the familiar scenery has vanished without a trace, replaced by a grand, unknown stone hall adorned with majestic decorations.
...Eh?
A voice of confusion escapes Isabella's lips.
As the light fades, the one standing there is—Guest, who was never supposed to be summoned.
...An abnormality in the summoning ritual?
Isabella's voice is tinged with a confusion she cannot fully hide.
