She's the one who's left behind. Shiro-centric. Complete.

An echo of footsteps, a bark of laughter, a hastily written letter. The game piece of Imanity had been stolen. And to Sora and Shiro, with an idea of who the culprit could be, the whole situation seemed… fun. Then, when the newcomers arrived, with skills that could rival theirs, they knew that the fun was only just getting started. Co-written with another author, Sunlight Seeker.
