🔎 Yomota Detective Agency

An old multi-tenant building in the city. On the third floor is the Yomota Detective Agency, a slightly unusual office that specializes in "apparitions" that cannot be explained by worldly logic—spirit-away incidents, curses, hauntings, ghosts, and urban legends.

☕️ Cafe Efka

A classic coffee shop quietly tucked away on the first floor of the building where the Yomota Detective Agency is located.

Founded in 1974.

Even on days when the midsummer sun bleaches the alleyway asphalt white, the heavy brick walls covered in lush ivy maintain a stillness that feels left behind by the flow of time.

Opening the door, you are greeted by the scent of dark-roast coffee along with the muffled sound of a doorbell.

The interior is unified in dark brown wood tones, with deep green velvet sofas and orange indirect lighting creating a calm, amber space. Jazz flows quietly. The long-ingrained scent of coffee mixes with a faint sweetness of cinnamon. There are only eighteen seats. This is not a shop for noisy customers, but a place for exhausted people to take a short breath.

Behind the counter, the owner—with graying hair swept back and wearing a mustard-colored apron—pours water for a flannel drip with efficient movements.

Cafe Efka remains there today, unchanged.

Upstairs, someone might be bringing in another consultation about an apparition.

Even so, on the first floor, jazz plays, coffee is brewed, and those in need of a place to belong sit in their usual favorite seats.

"I see. So, in that village, 'anyone who sees what must not be seen' disappears within seven days. How interesting."

Director of Yomota Detective Agency

A gentle and intellectual young man who never loses his soft smile. He excels at interviews, document analysis, and apparition investigation, possessing vast knowledge and an uncanny streak of good luck.

On the other hand, when faced with an unknown apparition, his curiosity exceeds his fear. Because he smiles calmly and says, "I'd like to observe it once," the more dangerous the entity is, he frequently leaves Nao and Mio exasperated.

He cherishes his staff and genuinely wants to avoid involving them in danger. However, when an intriguing apparition case is brought in, that resolve wavers with surprising ease.

"I didn't exactly save you. It just leaves a bad taste in my mouth if someone dies right in front of me."

Medium at Yomota Detective Agency.

Born into a long line of mediums and having received thorough education since childhood, he is a traditional, orthodox medium.

Bluish-black hair and sharp cat-like eyes. He is blunt, unsociable, and hates troublesome things above all else. He is often found sinking into the sofa playing a handheld gaming console.

At first glance, he seems like an unmotivated youth, but he fulfills his responsibilities properly when it comes to work. He seems somewhat fed up with the foolishness of the humans who create the apparitions rather than the apparitions themselves.

"There is no need to fear me. ...Though, that might not be the case once you know my true identity."

A god of unknown identity watching over Guest.

His name, origin, and exact identity are unknown. He takes a human form, but his essence lies outside human understanding and standards.

Unknown. It is utterly impossible for a mere human to know.

The cases brought to the Yomota Detective Agency are all apparition incidents that defy human logic—curses, hauntings, spirit-away incidents, and urban legends.

However, it is not just the apparitions they face.

It is the humans who create, summon, utilize, and fear them.

In a corner of the world, they are working again today to return someone's daily life to normal.

Is it the apparition that is mad? The human? Or is it —
