――Yatou Akari, an ordinary school girl attending an all-girls' school. Her grades are decent, engaging in club activities, and has a lot of friends. Perhaps because she has reached a certain age, in her room, on a spur of the moment, she masturbates. After climaxing with pleasure, she tirelessly opens her eyes and finds――
Not on her bed, not in her room, not even in the school dormitory, but a stiff stone paving, she sees a dimly lit place unfamiliar to her.
Wondering if this is a dream, at the moment when Akari tries to speak, she hears someone's voice, a strange figure appears before her.
"Ahhhhhh!? What!? Why!? Hold on. ......Eh? I? Have I mistaken?"
Shouting such things, the woman is clearly surprised and flustered.
Soft dark skin and long pointed ears. And the way she looks like she is wearing an underwear, Akari thinks that she sees something beautiful, while also thinking that this is a dream.
To see such a character that would appear only in manga and novels, she thinks, no, she must be thinking what an otaku she is to have experience such dream.
Maybe because she still feels the afterglow of her climax, she is very tired.
She thinks that she should sleep until dinner time, so she closes her eyes again.
However.
"No! No! No! This can't be! Why? Moreover, a human? Beside, isn't this just a poor loser!"
Although she has closed her eyes, she can still hears, an obvious insult.
Yes, she is a human, but she is not poor and her shape is not bad.
Even her breasts are bigger than most people, not that fat as well.
Despite this being a dream, why does she have to take these insults?
Her body is listless, Akari does not have the energy to fight back, such a rude dream, she sighs and wonders when she would wake up.
But, the harsh words toward her do not stop, interweaving with the words she does not understand, the woman's insult continues.
And finally, her patience is at the limit, trying to fight back, Akari forces her tired body to wake up.
"Agh, enough! What the hell is wrong with......you?"
......The dream comes true.
However, everything looks strangely real and vivid.
She can feels in it her hands, the coldness of the stone paving.
Dust, mold, and smells really old too.
Since this is a dream, is it possible to experience all of these?
Such sensations make her sound weak, as she begins to feel impatience and suspicious, even anxiety kicks in.
"What's this?" "What's going on?" "Where is this place?"
"How do I get home?" "Is the elf in front of me real?"
"Eh? I was masturbating in my room, wasn't I?"
"Wait a minute, what? When I came, did I go somewhere?"
Obviously in a panic.
The afterglow of her climax instantly blows away, feeling pale, her brains filled with questions, a helpless frustration.
As if the make Akari even more confused, the voice of insult turns into a deep sigh, and languidly informs her.
"Sigh....... You have been chosen to become the Maou of this world. If you don't want to die......If you want to go back to your world, do what I tell you, shitty human!"
"Huh? Huhhhhh!?"
