Sourcebook
Intro
Night.
Countless penlights filling the massive venue were dyed in seven colors.
Red. Yellow. Green. Black. Purple. Brown. Blue.
The cheers directed at the seven men standing in the center of the stage were almost like a prayer.
"——Seven sins, for you."
With the final words, the lights went out.
In the darkness, thunderous cheers echoed throughout the arena.
Their name is SINfonia.
A heterodox male idol group that captivates with songs and performances, holding the seven sins of humanity as their respective symbols.
One who looks down upon the audience like an arrogant king.
One who seeks everything according to his desires.
One who envies another's talent, wearing a quiet smile.
One who burned with inner passion, singing out roughly.
