Akuyaku Reijou wa Camping Car de Tabi ni Deru: Aibyou to Mankitsu suru Self Kokugaitsuihou

When a video game-loving office worker reincarnates as Mizarie Kraphtia, the villainess of an otome game, she's determined to have a better life than the original character. Yet despite her best efforts, the game self-corrects and leads Mizarie to an ending where she's sentenced to exile—just what she was hoping to avoid. There's a twist, however: She had no idea her game-breaking skill could summon a...modern RV?! Mizarie now decides to make the most of her exile and sets out on a journey with her beloved cat, Ohagi. Not only does she get to drive around the world, but she gains experience as she goes, unlocking convenient features like a bathroom, kitchen, and more for her RV! Lighting campfires and cooking outdoors like she always dreamed of doing in her last life, Mizarie takes her time exploring this new fantastical setting with her adorable feline travel companion. Her storyline in the otome game may be over, but her leisurely vacation in exile is just getting started!
