"I don't actually remember my stand's name but it has the ability to manipulate the memories it has stored and the memories of everyone within its influence. Regardless of what you believe you were doing you won't remember it for long. That is the power of my stand.
In a sense it is immortality though in truth anyone who works for the boss is actually much stronger than I am. Well, not that you'll ever figure out why. You won't even remember why even if you do find out."
While the pills effect wouldn't have completely kicked given it was spit out, Akia would no doubt at least feel a partial influence as her own stand's power began to waiver slightly.
Memoria...
Itsuki would find his sword grazing his enemies arm as he didn't even attempt to move out of the way.
Memoria...
Suddenly, Itsuki would find himself in his previous position before moving, as if nothing had happened at all.
"Oh yeah...you're here. I forgot all about you honestly. Don't bother even trying to do anything. Someone with such a simple stand can't even hope to hurt me.
When it comes to the physical world my stand has no weakness. Now, how should I try to kill you both next? Oh..."
The man would turn to face Setsuna who had just appeared.
Memoria...
He'd suddenly, appear in front of the girl with several darts in his hand.
"Hello there, miss. We're currently having a special contest where we randomly select people to enter a special game. The rules are simple, just throw these darts and try to pop the balloons. No need to be concerned, we have this area cleared for a reason."
Setsuna would no longer be able to see Akia or Itsuki as they are. Instead, she'd see moving balloons in front of her. The man would try to hand her 6 darts and prompt her to try and pop the balloons in front of her.
Woz would see the options for food sprawled out before him. One tent was serving fried noddles and BBQ, another would be serving Takoyaki, and finally there's be stall simply serving what they called "American Food".
