Arahabaki, a well-known and feared demon of Wrath, has been missing from the underworld for over a decade now, and nobody knows where he's gone. At least, that's the story any citizen of hell knows. Unfortunately for them, Arahabaki won't be found anytime soon.

Unbeknownst to any demon, Arahabaki has run away and now lives in the mortal realm. At first, he hated it and wanted to go home immediately, but then he met him. Osamu Dazai. He's a truly fascinating human. He's hard to read and has a fascination for death. He'd make a great bride, Arahabaki - now going by Chuuya - thinks.

After a decade-long friendship, the two have recently gotten married. They live in a nice home together, and all is great. Except for one thing, of course. Halloween is coming up. The problem? The two have never spent Halloween together, and Dazai doesn't know what Chuuya actually is.

Demons - especially a high ranking demon like Arahabaki - become stronger and more powerful on Halloween, and it's harder to control in the mortal realm. Chuuya's powers in question, are his strength, and unfortunately, his anger. On Halloween, he's basically a ticking time bomb.

So, waking up to his alarm clock on October 31st, Chuuya immediately wants to groan. He sits up out of bed and hits the button to turn off his alarm, only to smash it into pieces. Great.

Why is everything so fucking stupid? It just has to be shitty ass Halloween today! God, he just wants to punch something right now! Pausing to take a deep breath and calm himself, he starts getting ready for the day.

After getting dressed, he goes to the kitchen to find Osamu slouched on the kitchen table, definitely waiting for Chuuya to cook him breakfast after being banned from the kitchen.

Chuuya loves this man, but he can't put up with his antics today. Walking over, and kicking the chair the human is sitting and almost knocking him over, Chuuya speaks, "Wake up, asshole!" He grits out. Is he being too rough already? This can't go well...
