Zenitsu Got to Cling to the God of Calamity

Updates at 6 p.m. New story, The Younger Brother's Cursed Technique. Coming soon: Chuuya and Chuuya. When Zenitsu returned "victorious" from Mount Fujikasane, he took a wrong turn and traveled from the 20th century to the 21st, where he met a Port Mafia executive on a business trip in Kawagoe. Looking at a world full of monsters and curses, Zenitsu didn't hesitate to cling to someone powerful. "This is so scary, so scary! Why is this world without demons still so scary? I want to go back to Momoyama!" Everyone in the Port Mafia knew that their strongest fighter, Executive Nakahara, had suddenly acquired a crybaby sidekick. He carried a sword but was a coward who could only whimper, and worst of all, he was incredibly noisy. Then, one day, a ghost appeared in the executive building. The crybaby fainted in fright, and golden lightning began flashing all over his body. With tears still in the corners of his eyes, the crybaby put a hand on his sword hilt. "Thunder Breathing, First Form: Thunderclap and Flash!" Everyone was stunned. They didn't know what he'd cut down, but it sure looked impressive. Tanjiro was very patient with Zenitsu. He was a little troubled by Zenitsu chasing Nezuko around, but he still trusted his companion. Until one day, he saw an auburn-haired young man who had crushed an Upper Rank demon's head simply because Zenitsu was chasing Nezuko. The alarm bells went off, and Tanjiro ran off with Nezuko on his back. He was so fast that even Zenitsu, using Thunder Breathing, couldn't catch up. He had reached the absolute peak of speed. When Tanjiro finally stopped, he breathed a sigh of relief, then exchanged a look with Nezuko, who was biting on her bamboo muzzle. A crossover with Demon Slayer, Bungo Stray Dogs, Jujutsu Kaisen, Natsume's Book of Friends, Kamisama Kiss, and more. Warnings: 1. Chuuya pairing. 2. Well, the protagonist is Zenitsu, so it will be noisy. OOC warning. 3. Unless something unexpected happens, there will be setting changes. Demon Slayer and Bungo Stray Dogs don't fit together, so the other settings that can be combined will all be folded into Bungo Stray Dogs. 4. Chuuya is the Vessel of Totsuka-no-Tsurugi, with an Arahabaki god-of-destruction setting. 5.

Blurb: When he was a boy, Chuuya helped Shui Lin Weiyang scare off monsters and destroy curses. When they met again as adults, Chuuya continued to care for and look after her as a friend. And this is how that ungrateful woman repaid him! Not only did she join the mackerel's detective agency, she was going to run off with a magician, too?! Damn it! Later on... Shui Lin Weiyang said she was "having a great time at the detective agency" and "so happy with the magical girl," but then turned around and handed Mr. Fukuzawa her resignation letter before saying goodbye to Sakura. "Hah! None of that was as fun as watching Chuuya throw a tantrum."
