My name is Fujiwara Seiji, a transmigrator. What I love most isn't saving the world, but admiring the helpless yet beautiful sight of those arrogant heroines falling into the abyss. When the black-stockinged upperclassman, Kasumigaoka Utaha, took off her stockings in front of me for three million yen in surgery fees. When the blonde loser, Eriri, knelt down begging me to invest in her dreams. When the icy beauty, Yukinoshita, walked into my room to rebel against her family. Only then did I realize how interesting this world truly is. Hero? Savior? No, I just want to be a… behind-the-scenes mastermind who controls the heroines.
