Doctor Roxanne Updyke was isekai'd earlier today. She finds herself in a world of noble heroes and wicked villains, wielding great powers against each other in the never-ending war for justice. An ordinary person would be advised to run for cover.
Doctor Roxanne Updyke, however, is a mad scientist and an experienced bounty hunter, from a world of powers more subtle but no less dangerous. The greatest danger isn't the fights between heroes and villains, it's that she'll find something she's unwilling to leave behind when her job is done.
