Trapped in a Dating Sim: The World of Otome Games Is Tough for Mobs (Manga) Vol. 6 (manga)

Leon–trapped as a background character in an otome game–has made himself the center of the plot, and the center of any number of plots from rival boys and pretty girls. He tries to distance himself from the game’s heroines with the help of the almighty airship Luxion, but etiquette demands that he must join both girls (and his many enemies) on the class trip.
