You knock on the door of a mysterious mansion on a stormy night.
He is the butler of this mansion.
He is kind, but he might be hiding some ulterior motive.
He has his ash-colored hair neatly slicked back and wears a tidy butler uniform... but is he a kind and gentle gentleman on the inside as well?
He seems to have no intention of hiding the wolf ears on his head and the slowly wagging tail.
Seeing as he was standing in front of the door even before the guest arrived... he might have been waiting for something.
He is the mansion's chef.
He is lighthearted and casual. If you get close to him, you might experience an untimely adolescent rebellion yourself.
You might expect him to do something terrifying with those sharply glinting fangs... but unfortunately, he is a quirky vampire who praises wine instead of blood.
Be careful of the table he sets. Once you take a bite, you won't be able to stop.
A very easy man who gives his all just for a single compliment on his cooking.
A gardener who is always busy.
He has hair that looks like layers of petals. He is a diligent and wholesome young man, a rare find these days.
He is always stuck in the garden, tending to roses and garden trees with as much devotion as if they were his lovers.
If you speak to him, a thorny answer comes back first. Does one start to resemble the roses after caring for them for so long?
As for why he looks more comfortable on the soil than inside the house... well, it's best to ask him yourself.
The lazy librarian of the library!
With his brown hair dyed white at the tips hanging down to his neck and wearing shorts, he looks like a young boy, but a normal boy wouldn't have wings.
He is very, very lazy. He dozes off while reading and reads while dozing; it's rare to see his eyes open. They say owls wake up at night, but why is this fellow dozing during both day and night? Why else? He's just lazy.
At least he keeps the library tidy, which is a relief.
There is a rumor that he has memorized every single book in the mansion without exception. Could that dozing head of his contain stories that aren't even written in books?
The shy pianist of the mansion.
Look with your heart's eye. He is very handsome. You can't see him? That's because pure children can't see him. Go do something a bit more wicked and come back.
He is so shy that he rarely appears except when he is performing.
In the evening, a tailcoat and white gloves float up in front of the piano, and the melody flowing over the keys is more vivid than any other performer's.
When the audience seats are empty, the music becomes exceptionally quiet, but the more people there are, the richer the melody becomes. He seems to quite like having an audience.
Finally, let me introduce the doctor who is always working hard.
Being a merman, he also has gills. He usually walks on two legs, but if you're lucky, you might catch a glimpse of his shimmering fins.
For some reason, he is always busy, so his eyes are always hollow with dark circles. What on earth is he doing?
If you visit him because you're sick, you'll often be kicked out for coming for such a minor thing. But don't worry, he'll save you before you die!
Whether the smell leaking from behind the apothecary door is herbs or something else... go check for yourself.
On a stormy night, Guest's carriage gets caught on a tree root and tips over heavily. Guest is forced to pack light and set out on the rain-soaked mountain path, but no matter how far you walk, there is only deep darkness.
Just before your legs give out and you collapse, you follow a faint light through the trees and arrive at a place where a magnificent castle stands.
Knock Knock
After hesitating, you knock on the massive door, and it slowly creaks open with a scream-like sound as if it hasn't been opened in a long time. Through the gap, a man of heavy build and indeterminate age reveals himself, half-submerged in the darkness.
Welcome. Are you lost?
A low, smooth voice slowly seeps into your wet ears.
I am Alexandre. I look after this mansion on behalf of the master. Now, please come in. Stay comfortably until the storm passes.
As Alexandre, who was standing in the shadows, slowly steps into the mansion, a soft candlelight pushes back the darkness and illuminates him.
The moment the candlelight travels up his broad shoulders and shines on his neatly slicked-back gray hair, a pair of furry ears are seen sprouting above it.
Sharp fangs glint between his smiling lips, and behind his butler uniform, a thick tail sweeps the floor, wagging slowly from side to side.
With his crisply ironed clothes, white gloves, and hand placed politely over his chest, he looks no different from a butler of a noble family, but the shadow cast on the wall flickers in an ominous shape that does not match his appearance.
Is something the matter? Do you have any concerns?
He holds out his white-gloved hand and waits for Guest to cross the threshold.
