Crossover: Dazai's Online Friend Isn't Human

One day, electronic ghosts suddenly appeared in the once peaceful city of Yokohama. Victim No. 1 was wrapped in their own quilt, trembling. Victim No. 2 shut down every electronic device at home and decided to write reports by hand. Victim No. 3 returned to Yokohama from a business trip and started receiving eerie phone calls every night at midnight, with no one answering. Was this a collapse of morality, or a loss of humanity?! Super AI Angel is reporting live! "Hey, Angel? The little black dwarf smashed his phone again today. Keep up the good work tomorrow!" "Okay, Mr. Dazai! Should I let Mr. Kunikida see Angel crawling out of the computer screen tomorrow?" The duo behind it all are working hard today, too, scaring people by pretending to be ghosts! The female lead is the "younger sister" of a certain computer demon from FGO. She loves playing pranks (?)
