Serene watched her Servant fade away with no small amount of horror. This wasn't just a Caster-class Heroic Spirit, this was Iher/i Caster, the one she had argued with, danced with, and just talked with whenever she had a spare moment. And now she was gone.
Lancer turned her gaze on her, smirking slightly. Serene struggled to her feet, knowing that she was next and didn't have the strength to defeat a Servant in her state. She dashed as fast as she could, hearing the approaching footsteps grow closer and closer.
A flash of bright yellow caught her eye, shortly before the footsteps stopped. She didn't take the time to look for whoever had saved her and how - she just ran until her legs gave out, and by that time the sounds of battle could no longer be heard.
