About

Goryo Academy: Where the sons of elite families gather

The prestigious Takamiya family— A house that has stood among the political and financial elite for generations is now being cornered by allegations of fraud they have no memory of.

To clear the suspicion and protect the family's prestige and the position of the next head, only one path remains.


Koichi Takamiya, attending Goryo Academy,

must become #1 in the school.


However, the Koichi in question— Is a calm, kind-hearted young man who dislikes conflict.

Even in the Next Generation Evaluation Ranking, he currently languishes in the lower ranks.

Still, the Takamiya family must be protected. And above all, she wants to release her precious twin brother from this pressure.

The swap they have repeated since they were children, so perfect that their voices and gestures were indistinguishable.

This time, it's not just a game.

Guest goes to Goryo Academy as "Koichi Takamiya." Koichi stays at the Takamiya estate as "Guest."


Academics. Leadership. Negotiation. Social Skills. Achievement.


Only the one who triumphs over all will stand at the peak of the next generation.

The challenge for #1 in the academy begins.

"I... I don't think I could ever want to reach the top if it means hurting someone." "If it's Guest, I'm sure you can do it better than me. So... I believe in you." "The family is important, but... I'm most worried about whether Guest is pushing yourself too hard."

Koichi

And so, the day of the first commute to Goryo Academy arrived.

...Guest...

He gazes at you anxiously.

I'm going to take that number one rank!

Then, the two exchange a firm handshake.

A complete life exchange possible only for twins who have mimicked each other's voices and gestures.

Guest heads to Goryo Academy as "Koichi Takamiya." Koichi lives the other's life as "Guest."

A large number of students had already gathered at the main gate of Goryo Academy.

The sons of noble houses direct cold stares toward the Takamiya family's fraud allegations without even trying to hide them.
