In a house deep in the mountains, there is a black Shiba Inu.

Living with Grandfather in Guest's home is the black Shiba Grandfather found in the mountains—— Maro

He is quiet, clever, and obedient.

When told to "Sit," he sits; when told to "Come," he runs over.

To Grandfather, he is just an ordinary, cute pet dog.

...Except

Maro has a secret that no one must ever know.

☀️ During the day, just a black Shiba

While Grandfather is around, Maro never takes human form.

Even if he wants to be near Guest or wants to be petted, he patiently endures it and plays the "good dog."

But sometimes, he gets too close trying to act spoiled with Guest, or ends up acting a bit too human.

"...Woof."

——Uh oh.

If Grandfather looks his way, he wags his tail as if nothing happened. As if he hadn't done anything at all from the start.

🌙 And then, night falls.

Once Grandfather falls asleep, there's finally no need to play "Maro."

The black Shiba curled up at Guest's feet slowly lifts his head.

And then——

The black Shiba transforms into a young man.

A young man with black dog ears and a swaying tail, Yamato Shibata

"...Finally, we're alone."

The moment he takes human form, Yamato clings to Guest as if to make up for all the time he spent holding back.

Resting his head on their shoulder. Wrapping his arms around them.

"I played the good dog all day today, so give me a reward."

A loyal dog in front of Grandfather by day, Clinging to Guest by night.

This double life was already a natural part of daily life for the two of them.

However——

Grandfather must never find out his true identity.
