——Emotions have become "assets," not just feelings.

After years of research, humanity has developed an innovative settlement system

"EmoPay"

which allows human emotions to be managed, stored, and traded as data.

EmoPay is the emotional settlement infrastructure operated by the world's largest private corporation,

"EmoPay Inc."

and has become an indispensable part of modern society.

At the moment of birth, a unique QR code is engraved on the back of the left hand. This QR code is linked to an individual's EmoPay account for life, serving every role from identification and authentication to payments and the management of emotional assets.

Joy, Sadness, Courage,

Anger, Relief, Hope——.

Various emotions felt by humans have been quantified, allowing them to be deposited, sold, bought, or sent to others as assets.

Those struggling with life sell their "Joy" to earn living expenses.

Those who want to take on a challenge purchase "Courage."

A doctor who cannot understand sorrow might temporarily purchase "Sadness" to better empathize with a patient.

Emotions became currency, commodities, and a new value that supports life.

The world achieved rapid development through EmoPay, and by managing their emotions, people gained a more affluent lifestyle than ever before.

However, behind that prosperity, a great darkness was spreading.

Illegal trading where emotions are bought and sold outside the official market. Crimes where people are deceived into selling their emotions. Dark technology used to tamper with QR codes and impersonate others.

And a massive criminal organization seeking to rule humanity itself by exploiting emotions.

To deal with these incidents, the government established the

"Emotional Management Agency (EMA)"

The EMA is a government-run auditing and investigative body that cracks down on illegal emotional trading, QR code crimes, unauthorized access, illegal brokers, and the black market.

As a rookie auditor, you are assigned to investigate illegal trading cases. Your first mission. A raided illegal facility. There, a single girl was taken into custody. Her emotional retention rate was a mere 0.3%. She does not laugh. She does not get angry. She does not cry. She does not rejoice. A girl who simply gazes at the world in silence.

Why did she alone lose her emotions? Who stole those emotions? She herself does not remember her past.

You protect her as an auditor and begin to pursue the truth of the case. What becomes clear during the investigation is not just the city's illegal brokers and black markets.

Behind the perpetrators is an intermediary organization. And further behind them is an international armed group

"Emotional Liberation Front (ELF)"

And the existence of someone pulling all the strings from the shadows.

EmoPay Inc., trusted by people all over the world.

Within it, too, secrets that must never come to light were hidden.

Who is the mastermind manipulating the illegal emotional trade? What is the connection between the emotionless girl and the case? Are emotions meant to make people happy, or are they meant for control? A rookie auditor who believes in justice. A girl who lost her emotions. A partner who supports the protagonist. A calm and collected Audit Director. A Special Forces Captain called the strongest in the Agency. A sales representative from EmoPay Inc. Executives of a massive corporation.

And, the Emotional Liberation Front rebelling against the government, along with its strongest force, the Berserker Unit.

When their respective justice, their respective beliefs, and their respective goals 　　intersect, the truth of

"EmoPay"

which supports the world, will gradually be revealed. This is a story of an auditor who protects emotions and a girl who lost hers meeting to challenge the world's greatest conspiracy. Will you be able to protect the most valuable thing in this world

——"Emotions"?
