Hara Miko Shimai

After an earthquake, monsters from folklore roam a quiet island just off the coast of modern Japan.
But the legendary exorcist maiden Miko from the past is here to battle them!
Take control of her and restore peace to the island!
(While not the whole world, the island is open for you to explore!)
Miko may have forgotten a few things during her long, long sleep, but there's nothing like some intense fighting to shake up her memory.

This is story about a manga artist who is dissatisfied with his work and draws adult manga under a different name. He finds himself at a resort called "Costaria," where he encounters a pair of sisters who want to act out the scenarios from his adult manga.

One day, I lost something precious.
I went to several cosplay events, and took some pictures to satisfy my lust. However, the camera that contained all the pictures was destroyed in an unfortunate accident.
Perhaps they didn't want to see my cry anymore, the Yamakake sisters, Sana and Yua, who were involved in the accident, said to me;
"Would you like us to cosplay for you instead?"
I accepted their offer.
Their bodies look lewder than anything that I have ever seen in any erotic manga, and they were willing to be my very own cosplayers!!
I put the skills I learned as a fashion student and my hobby of making costumes for dolls to good use, creating costumes for the sisters, and as luck would have it, I was given tickets to the cosplay resort "Costaria", located on a remote island.
This was an opportunity for me to get the best portraits in Costaria. However, what awaited me on that island was so much more than I could imagine!
"Let's have a different kind of cosplay today."
"Erotic role-playing. You'd like that, wouldn't you?"
The sisters whispered those words to me.
With my very own cosplayers, I'm going to make extreme and intimate portraits that cannot be shown to anyone.
I wonder if it's okay to make them──

[Before the figure sculptor who had settled in the remote island cosplay resort “Costaria” appeared... A pair of voluptuous and busty cosplayers, the “Ikura Sisters”!]
I, Aizen Tsukuru, am a figure sculptor.
When it comes to enhancing the charm of 2D characters to 3D, I refuse to make any compromises. That’s why my rigorous approach to figure creation has been highly praised.
In my pursuit of perfection, I arrived at my ideal paradise— “Costaria”. It was so comfortable that I spent so much time working there and before I knew it, people started calling me a “resident of Costaria."
However, a trial soon came my way.
"A cast-off... erotic figure?!"
As a virgin, I had no real knowledge of the female body, which prevented me from creating figures that truly satisfied me.
I was at a loss, feeling like a failure as a professional. But then, appearing before me were the Ikura sisters— two girls that just made their debut, wrapped in dazzling cosplay outfits that accentuated their voluptuous, dynamite bodies.
"Please, make a figure of me using your hands!"
Is this really happening?
Those voluptuous, perfectly curvy bodies— it's as if they stepped right out of my imagination.
Dressed in provocative cosplay outfits, can I really go ahead and create the ultimate erotic figure with them?!"

The protagonist, Kazama Yukiya, was living a student life while earning money through his own method of exorcism and purification, in addition to receiving financial support from his parents. One day, men in black suits appeared at his place and forcibly took him back to the countryside. They were the messengers of the "main family", and Yukiya is informed by the head of the Kazama family at the mansion where he was taken that Hisame, a shrine priest he had adored like a real brother since he was young, has passed away.
Astonished, Yukiya is immediately told by the family head, "Become the shrine chief to protect the company and take on 'a certain troublesome matter' with the shrine maidens. You have the talent for it." Confused, Yukiya hears about the "troublesome matter" from the three charming shrine maidens and reluctantly accepts the task.
