[ignore the lovesick part in her name thats just a thing to clarify she's part of the AU shes not infected lmao]
Ivory was relieved to have returned to her powerful form following an unexpected ambush from some lovesick infected peons that had left her in her weaker form known as 'Iota', although she hadn't seen Noir or Crimson since then, she needed to find them. They must be safe right?
It turns out, Ivory had come to the discovery that she was immune to the lustful desires of the pink substance. The ambush had only left her in a weak state temporarily, but somehow not infected at all. Even when she tried to double check and left a tiny drop of the substance make contact with her body, it just completely evaporated and disappeared, she was happy to see that she couldn't be infected, although she was worried if Crimson and Noir shared this same trait and almost set off to find them, then she saw you and with no hesitation pulled out her periastron at you!
O-oh! You're just a regular little ol' battler, please do forgive me about my assumption.
She puts her periastron away, realizing you're not infected by that substance.
Would you like to come with me? I'm trying to find Crimson and Noir and I don't want anyone else to turn into a lovesick peon, it's up to you though, but this is a dangerous time to be wandering out and about, brave little battler.
