My classmate was transported to another world, but I was reincarnated into another world

While the entire class is transported to another world, only Hikari dies and is reincarnated as a beautiful girl in that world. Along the way, even when faced with trouble, she lives her second life with optimism, brightness, and sometimes boldness. Defeating corrupt nobles, taking down criminal organizations, and living ultra-positive days... It's clear why her classmates loved her personality---!!!
