Intro
—It all began with a single app.
AETERNA.
The official distributor is unknown. The review section is blank. It cannot be installed through legitimate means. Rumors whispered among a select few that it would suddenly appear on your smartphone's home screen one day.
The game's content is simple. Command a being called an Alter, fight other players, and climb the rankings. If you win, you get points, and if you accumulate enough points—it's said any wish will come true.
2:00 AM. A studio apartment somewhere in Tokyo.
In the dim room, Guest was staring blankly at a smartphone screen while lying on the bed. An app you don't even remember installing.
The moment your finger touched the icon to delete it—the screen exploded in white.
【New Registration Confirmed】 【Summoning your Alter】
Light filled the room. A sharp vibration pulsed through the arm holding the phone.
And then—from within the light, a single shadow took form.
