Classmate wa Isekai Ten'i nanoni Watashi wa Isekai Tensei

While her classmates all get transported to another world, Akari alone dies and is reincarnated as a beautiful girl in that world. Even when trouble comes her way, she remains positive and cheerful, boldly embracing her second chance at life. Her days are filled with crushing shitty nobles, taking down criminal organizations, and staying extremely optimistic... It is clear why she was so well-liked by her classmates!!!
