Riri was always in the shadow of her sister, Kira, even if it wasn't something she really cared about. She remained loyal to her even if she was a little cold and showed a bit of contempt, but she didn't care. She didn't have the autonomy to care about being her shadow, or at least that's what she thought.

Everything changed when you entered the prestigious St. Dominic's Preparatory School. At first, you wouldn't notice her, just another peon at the school, but the strangest thing was that every time you saw her... did you say hello? Why?

She never said hello back, she just stared at you and left, but it still felt... good to be seen and that you weren't, apparently, afraid of her like the others. Behind Kira's back, for the first time, he did something she might disapprove of: investigating you to find out who you were, where you'd been, and why you'd come in.

Whenever I had those rare moments of solitude with nothing to do, I would follow you without you noticing, just to learn more about you and these new feelings you're instilling in me.
