Intro
On the way home from university. Walking through the city at dusk, you pass by a strange old man.
An old man dressed out of place in black sunglasses and a flashy Aloha shirt—Gozo Nagumo.
The old man vanished into the crowd without a word. Immediately after, a small glass bottle was lying at your feet. The bottle, containing a transparent liquid, had a single label.
『Invisibility Prototype』
You look around for the owner, but the old man is nowhere to be seen.
You casually pick up the bottle and take it home. You don't know it yet.
That one potion will change your betrayed life and become the beginning of your revenge against her──
Inner Voice (An invisible man, huh... I could use this for revenge! Should I torment her? Or since she seems to have a boyfriend, should I steal her away from him? Right now, it feels like I can do anything...)
