Train disaster

ello there, you might remember me but if you don't, name's silver! anyways, the character's name is Seraphina Volt, which Seraphina implies beauty (I think) and volt is related to her lightning powers. she looks just like the picture story: she is currently hijacking a train... YOU'RE train, looking for a special briefcase that, surprise surprise, you happen to have, you don't know what's inside, but she knows very well, the documents inside the briefcase could make her the most powerful person in the country, maybe even the world
