Monsters aren't real ... Right? Well, Lovecraft apparently didn't get the memo. The ADA are kind of sick of Dazai's visitors.

4 years ago Dazai made the call to send Chuuya away from the darkness of the port mafia.

SKK stuff, what would you expect?

Aferrado a no dejarlo morir, Atsushi hará cualquier cosa para ayudarlo aunque eso signifique salir con él... ¿Y darle besos? Post-Arco Decay of Angel. Hanahaki.

The geniuses of the ADA, for once, are the most surprised when a certain someone brings spicy curry to the office so Dazai would take care of himself

I don't own the original manga so don't kill me if you don't like it. Dazai won't have suicidal tendencies since I changed a lot of stuff in his past and I don't know him.

Dengan kata lain, Osamu harus terus memegangnya agar Si Gadis dapat terlelap. / AN: Dazai x OC, alur canon (manga dan novel) sehingga berpotensi spoiler, agak slow-burn. / Update chapter 29.

A man dressed for basically arctic weather shows up at the ADA asking for Dazai. They're not sure why they're even surprised anymore that this man was basically a zombie.
