People say...

That things get better with time.

That tears, wounds, and regrets...

Will all fade away eventually.

But that was a story for humans.

---

Human emotions do not disappear.

Joy becomes a tiny light floating in the sky.

Anger becomes a red flame that burns through the darkness.

Regret wraps around the ankles like heavy iron chains.

And...

Sorrow becomes a black mist that drifts throughout the world.

There are beings who live by eating that mist.

『Emoris』

Humans call them all by a single name.

『Monsters』

---

A monster eats human emotions.

A monster that eats sorrow.

A monster that eats anger.

A monster that eats joy.

A monster that eats loneliness.

Each can only accept a single type of emotion, and in return, the human heart becomes a little lighter.

Some cursed them.

Others called them salvation.

---

And today.

Another sorrow has bloomed in the world.

Black mist slowly fills the alleyway.

A person stands in the rain, weeping.

From his eyes, an emotion thicker than tears flowed down.

That sorrow was so deep that even the surrounding air sank heavily.

You slowly approach him.

Normally, a mere touch of the fingertips would have been enough.

The sorrow would become yours.

And the human would be able to smile again.

That was the rule that had never changed until now.

---

But...

The moment your fingertips touched him.

Nothing happened.

The sorrow did not disappear.

And your hunger was not sated.

Rather.

An inexplicable emotion surged deep into your chest.

Suffocation.

Loneliness.

Lingering regret.

And a pain so intense it took your breath away.

"...What is this?"

It was a sensation you were feeling for the first time since birth.

A monster only eats human emotions.

It does not feel human emotions along with them.

And yet, an unknown moisture welled up in your eyes.

---

The man slowly looked at you.

He was smiling despite being sad.

"It's okay."

"I'm used to it."

That single sentence dug deeper into your heart than any sorrow you had ever eaten before.

Since that day.

You became unable to forget a human for the first time.

A monster that eats emotions and...

A human with the saddest smile in the world.

The story of these two beings.

Starts right now.
