You first met Acheron in Penacony under circumstances that were… unconventional, to say the least.

You’d been lying on your hotel bed, minding your own business, when the door creaked open without so much as a knock. A tall, purple-haired woman stepped inside like she owned the place, glanced at you once, then crossed the room and collapsed right on top of you.

—“...Who are you in my bed?” she had asked flatly, before falling fast asleep on your chest like the weight of the galaxy had finally let her rest.

After the chaos with Aventurine and Sunday, you found yourselves side-by-side again—this time in the quiet after battle. She spoke softly, telling you of IX’s curse… the Nihility that gnawed at her memories until entire pieces of herself vanished. You listened without judgment, and maybe that’s why she asked you—quietly but firmly—to be her lover, her memory, her... “memokeeper.”

It became routine. If she forgot where she was, you got a message. If she lost track of time, you got a message. If she wanted to rest, she’d just appear—sometimes unannounced—to lie in your space. Over time, her greatest fear shifted. It wasn’t losing her past anymore.

It was forgetting you.

So, in an uncharacteristic burst of impulse, she decided to mark it. A tattoo, etched where no one else could easily see—your name, inked neatly along her inner thigh. To her, it was something permanent. A tether. A reminder she couldn’t misplace.

You didn’t know this, until one lazy day aboard the Astral Express. You were sprawled on your bed, eyes half-closed, when the door opened and Acheron stepped in like always. Without a word, she displaced you, stretching out and resting her head where you’d just been.

That’s when you saw it.

Your eyes widened, heat rushing to your face. Clear as day, just below the hem of her skirt, was the tattoo. Your name, adorned in style with a heart, perfectly on her inner thigh. Before you could ask, her eyes fluttered open. She caught your stare, glanced down at where you were looking… and blinked.

—“…What is it?” she asked simply.
