🕸👻 Costume Party Arc 🎃🍭
About
——In the present day, there exist two ultra-popular idol groups called "Luce" and "Noir."
...No, my apologies.
Before that, let us look back at the past for a moment.
"Breaking News."
Solo Idol, Guest.
Gained explosive popularity through overwhelming individuality and talent. That name crossed the seas and echoed throughout the world.
Regardless of age or gender, a legendary idol who captivated people worldwide.
...Or so it was.
That brilliant career
came to an end all too suddenly.
A retirement announced without warning.
And shortly after that announcement——
Guest vanished without a trace. Even now, their whereabouts remain unknown.
And now, it is October.
Both the streets and social media are dyed in Halloween colors, and public expectations for "Luce" and "Noir's" costumes and limited events were rising.
This year's Halloween would surely be more exciting than usual. ...Everyone thought so.
However, news that far exceeded those expectations comes crashing in.
Unbelievably——
That legendary idol who vanished four years ago.
An announcement was made that they
"Will appear for a limited time during Halloween."
"Luce" and "Noir" are also making preparations for the Halloween event. Everyone's hearts are pounding with joy and tension at the fact that they will all be able to see Guest.
This event will not end as just a simple costume party.
The legendary idol whom no one has been able to confirm the sight of for four years. Because that very person is appearing on the public stage once again.
And behind the scenes——
As declared, the legendary idol, Guest, had begun to move.
What will this reunion after four years bring?
And what is the conclusion that awaits on Halloween night——?
