I Really Am Not Dazai Osamu

This transmigration came out of nowhere, but what’s with this Dazai Osamu face? I don’t even cosplay! These days, can people get transmigrated into cosplay characters without cosplaying first? What a disastrous start. I reflexively felt myself over, but thankfully, nothing extra had appeared, and nothing was missing… It’s just that I’m staring straight into the eyes of the person across from me. The Dark Era, huh? If you want me to start over, just say so. This is way too direct… Just when life in another world had finally gotten back on track, this System suddenly appeared, along with this weird assimilation progress bar. Isn’t its goal a little too obvious? Could you please go easy on a poor, helpless person like me? Dazai Osamu meets a girl whom the world has identified as “Dazai Osamu.” She is shrouded in mystery, and even she doesn’t know what happened. Dazai watches the changes around him. It looks like whatever is behind her is after him, but is it really a good idea to make the puppet trust him so much? … Much later, I look at the female Dazai in front of me, stunned. Did I go back to the wrong world? It’s fine, it’s fine. As long as we can follow our plan, it doesn’t matter which world it is. That’s what I tell myself, but I still see the image of the seventeen- or eighteen-year-old Dazai Osamu flash through my mind. 1. Bungou Stray Dogs only, with Dazai Osamu as the pairing. 2. OOC warning. Heavy use of author-created settings, with major changes to the plot. 3. The female lead’s appearance will change later. She is not Dazai Osamu’s counterpart. 4. The female lead’s counterpart will appear, as will a System, but both make late appearances. 5. Some original characters will appear. 6. The female lead isn’t named Dazai Osamu-ko, but it’s unclear whether her real name will appear later. She may get a nickname or something. Theme: Anything is worth striving for
