Yokohama's Intermittent Haunting Syndrome [Crossover]

1 My name is Nekoyashiki Satou, and I'm a ghost. I'm determined to become the big boss of the ghost world, the most badass person around. That new guy, Kibutsuji Muzan, is pretty full of himself. He eventually became my underling. I have a great best friend named Kochou Shinobu, a loyal fan named Haurchefant, and the new guy Matsuda Jinpei is pretty handsome too. Time passes for us like air. Later, more and more people start showing up beside me. There's Oda Sakunosuke, who loves spicy curry; Dio, who drives a road roller every day; and a little girl named Enma Ai living next door. I also start to realize that something's not quite right. Let me say it again: I really am a ghost. Kayako is my best friend, too! So why! Did I! Suddenly! Turn into a human?! Even if only sometimes. In the end, I became a ghost with intermittent human symptoms, along with a bunch of ghost underlings. Now I'm going to take over Yokohama. 2 The Port Mafia faces an eerie abandoned-house haunting, a once-in-a-decade occurrence. The materialists are stumped, so they can only send their chosen errand boy, Nakahara Chuuya, to handle it. Nakahara Chuuya angrily declares, "I'd rather die outside! I'd jump out of here! There's no way there are ghosts here!" Then a woman with a dark mark between her brows floats through the wall, takes a look at him, and says, "Oh? It's you?" before floating back out. Two minutes later, she floats back in with a new ghost. Nakahara Chuuya blinks, then blinks again, and finally his eyes go wide. "...Rimbaud?" Nakahara Chuuya goes home that very night to burn incense, pray to Buddha, and seek out a venerable monk. - The Agency keeps getting requests to exorcise spirits. The materialists are on the verge of a breakdown. "We're not venerable monks! This is a detective agency, not a temple for detectives!" Satou, the new temp worker, always looks pale, with a dark mark between her brows. She clears her throat and stands behind the client. "Don't worry, I'll take care of it." The vengeful spirit drops to its knees with a thump. "Lady Satou, what are you doing here?! Please spare me, Lady Satou!" The client beams with delight. "Oh my! I feel so much lighter!" Everyone: What just happened, Master Satou?! - Satou has a terrible temper, likes seeing people have a hard time, and loves dancing on graves. The first time she tries potato chips, she looks delighted. "Oh my?! These taste way better than those whatever-melon offerings!" The members of various organizations lurking nearby to gather information: (Too scared to make a sound.) Rumors of a ghost king begin to spread through Yokohama... They say she's a ruthless woman who kills without blinking... They say she commands countless troops beneath her skirt. To avoid falling behind, the various organizations all send people undercover. Satou: Huh? The ghost king? Don't believe rumors or spread them. Can we talk about science? Satou: I want snacks, and I want hot pot! Everyone: ... Everyone: Did I come in through the wrong door? 3 Satou doesn't even want to do anything serious anymore. She just wants to lie flat, but people keep taking issue with her. When faced with a feng shui master who claims to be an expert, Satou simply stands there and wiggles a finger. The feng shui master's ancestor appears and starts yelling. "You little brat! What are you doing here, stirring up trouble for no reason? Go home and copy scriptures!" Feng shui master: ...??? Feng shui master: Why did you bring my family into this?! The people standing nearby swallow nervously and offer her a plate of potato chips. "P-please, have some." 4 Satou finally realizes that being human really is more fun, but... why are there more and more people around her? In the end, she becomes a mysterious ghost boss with a bunch of underlings, both human and ghost. -The worldbuilding is just something I made up for fun when I was a kid. The original work's elements appear at random. I write whatever comes to mind. -The heroine may not end up dating any of the male leads, but one-sided crushes from male characters are possible, so I added the romance tag. [No CP] is more likely. -The heroine is the strongest both physically and in the supernatural sense. It's a no-brain power fantasy, so readers who want to scrutinize it should proceed with caution. -This is about a ghost who focuses on her career but keeps accidentally triggering romance routes. -A few stories about people who were gone suddenly appearing before you again as ghosts. -A story about why everyone, led by Kunikida, is always screaming. Theme: Superstition is bad, long live materialism!
