クラスメイトは異世界転移なのに私は異世界転生•

Classmate wa Isekai Teni nanoni Watashi wa Isekai Tensei

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