Forced to Follow the Plot After Cosplaying Shirase Yuzuha

System, transmigration, such ordinary words. But what if you transmigrate into the role of an evil side character?! At the arcade, two people boldly recited their lines, counting on no one being able to see the screen. “They tell me to buy medicine, so I buy it. Doesn’t that make me look pathetic?” “You’re really going to stab him...?” “...From the way they talk, they want me to use the one I carry around? What did I do to deserve this...! With a knife like mine, how deep would the stab go?” “You say that like you could actually stab someone.” “Yuzu An, let’s run away together after I stab him.” “??? Are you sick?” “Hey? Yuzu An-chan, that’s so hurtful!” “Bai Lai, your character is falling apart.” “I’ve been sick of those Sheep people for ages! If only I’d taken you all and run away as soon as I found Chuuya. Waaah...” Yuzu An: “Ugh! What happened to your character? What happened to your scumbag persona?” Dazai Osamu, who had secretly planted a wiretap on the two of them at the arcade and heard every word: “Oh my, looks like I’ve found something fun~” A very standard transmigration-and-amnesia setup. A System-led growth story. Neither of them has supernatural abilities. Bai Lai x Yuzu An Theme: You can live without a character persona
