[Crossover] The Daily Life of the Flame God, Master of Swordcraft

The first time I started questioning my life was when I picked up a sword ledger that someone had sent me, though I had no idea who. Kashu: I am called the Child of the Kawasemi... After repeatedly confirming that the man before him had appeared out of thin air, Kagami, who had seen a ghost in broad daylight, fainted from fright. Kashu: ...At least let me finish talking before you faint! After accepting at an unexpectedly quick pace that he had become entangled with a sword nerd who called himself a Tsukumogami, Kagami let the guy eat and drink for free at his house, and accidentally gained a new title: Saniwa. He also had to take on the infuriating task of retrieving swords. #Everyone else gets a Book of Friends, so why are all the swords I collect black? What am I supposed to do?# The second time was when a neighbor moved in next door at some point without him noticing. Kagami: Um, your head's on fire. 27: Ah, please don't worry about it. Kagami: ???? #My neighbor's head keeps catching fire. As a firefighter, I have an occupational urge to spray him with an extinguisher. What do I do?# A cast of people who don't do their jobs. Can't they just play basketball, be mafia, or be a Saniwa properly? No. Get lost. One-on-one. A battle-hardened, gentle, cunning godfather top x a tough guy bottom who gets flirted with and swept off his feet without even realizing it. The swords: Master, come back! He's a carnivore in a bunny suit! 27 (smiling victoriously): Too late. Warning: 1. The timeline is set five years after 27 inherits the Vongola. He's a 21-year-old black bunny who looks completely harmless. 2. A series where nobody plays basketball. 3. Sword retrieval and redemption route. 4. Everyone adores Kagami, through a very rosy filter. 5. Any discrepancies with the original work are just the author's alternate setting. Canon purists, please be gentle. 2333 6. No writing in isolation. Everyone should care for authors living in empty nests. (Hey!) After talking it over with my editor, I've decided to go premium on Friday, February 9. Three chapters will be released that day. Please note that Chapters 25 through 33 will become paywalled retroactively, so if you've already read them, don't accidentally buy them again! Thank you for all your support. (Bows deeply.) He is a hero. Centered on Izuku Midoriya. As usual, it's crack pairings, with the familiar formula and the familiar bald head (?). Updates whenever inspiration strikes (please bookmark and comment). Link to the upcoming story: The Adorably Rude Chubby Master (Why does everyone like chubby people? They just like you.) Link Theme:
