A Handbook for Raising a Black-Hearted Spirit

[Please read the content warnings before you start. I'll try to update daily. Updates will usually be at six or nine each evening.] Dazai has a girlfriend: gentle, thoughtful, clingy, and with eyes only for him. After his colleague Kunikida finished receiving the beautiful woman who had specially brought over a cake she'd baked, he glared at the man leaning against the window to watch his girlfriend leave and said, "If you've already got a girlfriend, quit acting like such a flirt, you bastard! Don't break her heart!" Then one day, Dazai's girlfriend suddenly disappeared. Looking at his partner, whose mental state was clearly not right, Kunikida felt like his entire world had turned upside down. Meanwhile, the great detective sitting to the side, eating snacks and drinking soda, slowly revealed a smile that said he'd seen through everything. - Kuze Haruri has a boyfriend: possessive, clingy, and terribly insecure. Because of her ability, he's always insisting that she stay by his side, ready at any moment to be kissed, hugged, and swept off her feet. But one day, despite all her boyfriend's precautions, he let his guard down for just a moment. After blinking and suddenly finding herself in another world, Kuze Haruri let out a deeply troubled sigh. She was a little worried about her boyfriend's mental state. He turns into a walking ball of gloom as soon as she leaves. Will he be all right in that world? A story where everyone thinks, "You can't live without me," but it turns out, "I can't live without you." Pairing: Dazai. *Apologies for any OOC characterization. A nontraditional story of mutual salvation between the male and female leads. The female lead is far stronger than the male lead. -Recommending an upcoming story.

"My Secret Identities Dote on Me, So I Enter Hell Mode" Kurusu Aya is a repair worker created by the Lord God to fix world data. She has only one world to manage. It should have been a very simple task, but unfortunately, this world has too many problems. To make repairs easier, she takes on a different identity every time she enters the world. And for some reason, she can't take those identities with her when she leaves, so she can only split off a wisp of her consciousness and leave it behind in the world. Over time... the world is on the verge of collapse because it contains too many fragments of her consciousness!! So she has no choice but to enter the world herself and retrieve the consciousness fragments she's scattered. She planned to use rough methods and finish the job quickly, but things gradually started to go in an unexpected direction. Looking at the cunning magician, the cold-blooded assassin, the chart-topping star, the Mafia executive, and the special-grade sorcerer who all obey her without question... as well as the troublesome people she got involved with through her secret identities when she was young and reckless, Kurusu Aya was utterly speechless. - Recently, everyone has noticed something terrifying. Those people who had once been labeled [Extremely Dangerous] seemed to have been working for one person all along. No matter their gender, just mentioning that person made them turn into utterly crazy... bootlickers. Everyone: Heh. What kind of person is so amazing? Let me see for myself. Unrequited love arrows fly everywhere, and love triangles are all over the place. [Recovering souls means that the secret identities, including the protagonist herself, must die in that world in a plausible way. So to everyone else, this story is a truly, truly tragic bad ending. But once the protagonist returns, she has a wonderful time with her little secret identities.] No pairing in the main story. Theme: Kindness can cleanse the darkness.
