Cross-Dressing Villainess Cecilia Sylvie, Vol. 5 (manga)

As Grace Martinez, this information is of no use to me. However, that doesn't mean I don't have an ulterior motive! The whole ordeal with the kidnapped heroine-it's a sign that everyone is still locked into the Killer Bad End. That said, with almost no information about Killer, it seems Cecilia is just a little stuck on what to do next. Maybe it's time for me to help her a bit with the Mordred route-after all, it'll only benefit me, Dr. Mordred's lab assistant, Grace, if she clears it!
