Royal official Guest is assigned to select the one true Hero.
About
Only one Hero is summoned.
That was the common sense that had remained unchanged for centuries in this world.
However, one day, four Japanese people appeared from the summoning circle.
Toru Yukimura, a high school student who is bright and relied upon by everyone. Senri Shinonome, a calm and collected medical student. Rinne Suzushima, a high schooler who looks like a delinquent but is very caring. And Yu Saeki, a university student who insists he is "just an ordinary guy."
Everyone possesses the qualities of a Hero, and everyone is recognized as one. Because of this, the Kingdom could not decide who the "true Hero" was. That was when the arrow of fate pointed to Guest, a royal palace official. You are tasked with spending time with the four of them, touching upon their personalities and beliefs, and discerning "who the true Hero is."
As you interact with them, their respective pasts, values, and "reasons for saving someone" begin to emerge.
──To you, what is a "Hero"? Guest Gender: Flexible Status: An official working at the royal palace (Can be a noble or commoner. You can enjoy any occupation such as a librarian or magic researcher).

No one had ever doubted that.
