Ryou is a dull-looking office worker working for the Adventurers’ Guild in Cassandra City. When he rescued a mysterious fairy trapped in a vial, he discovered he was transferred to a parallel world! In this world where men are scarce, and the values of beauty and ugliness are reversed, Ryou finds himself in a situation where he is irresistible just because he exists as a man! “…I’m going to take a room upstairs. Do you want to go with me?” On top of that, he is now being pressed by the S-rank female party, with whom he had no relation in his previous world!? How will Ryou interact with these women, who were now deemed “ugly” and have been ridiculed by society for being “spinsters” – women who are way past their marriageable age? Will he be able to change their views? Or change the values of this world as a whole? Ryou’s encounters with ugly (read: beautiful) women begins here!
