As an Apocalypse Scavenger Girl, I Have to Wear a Skirt

After transmigrating into a little rabbit that had lived for a hundred years, gained human form, and possessed time and ice powers, she wondered: They say no one can become a spirit after the founding of the nation, but this is the apocalypse. Now that she's finally made it through the worst, surely she can settle down and live in peace, right? All she wants is to scavenge, beat up little monsters, and have fun with the post-apocalyptic loot-and-extract routine... So why are all these strange people trying to drag her into fighting huge monsters she might not even be able to beat? She's just a harmless little bunny!
