Eroge no Akuyaku ni Tensei Shita node, Mob ni Naru Koto ni Shita

Synopsis

I awoke to find myself reborn into the world of And Then the World Turned to Love, a popular eroge. Unfortunately, I had become Nishikikoji Kaede, the villain whose fate is to meet ruin in every route. While it's thrilling to be near my favorite heroines, the game's inevitable path always leads to disaster. To enjoy this beloved world peacefully, I resolved to observe the heroines from a distance and play the role of a mere mob character... but fate had other plans. My innate desire to help led me to assist the struggling heroines, and before I knew it, I had grown close to all three. Meanwhile, the original protagonist's behavior has started to become unsettling... I can’t remain a mob character any longer! This is a story of reincarnating into an eroge, full of harem romance and comedy! (Source: Kadokawa, translated)
