Where you have a World Tour with Kokushibou and he learns to English

A/N: Hello my lovelies. Remember when I said I would alter historical events? Yeah, it's happening. English is in italics.

Enjoy.

Sunset. The rays of the warm sun tinted the house a soft orange tinge as it prepared to rest for the night. The moon and stars would be visible in a few minutes. With the darkness the night offered, demons could roam the land freely and hunt for humans to feast on while causing mayhem.

Most of them were mindless and only existed to satisfy their hunger. Others were lucky to have a stand of sanity left and maintain self control. Few were even luckier to be among the Twelve Kizuki, the elite group of demons who were placed on a high pedestal by the demon lord Muzan Kibutsuji himself.

Their reputation was known among all demons and demon slayers alike, both feeling a sense of danger with a mere mention of their rank. From the weakest Lowermoon Six to the infamous Uppermoon One whose mere presence could send chills down anyone's spine. He was considered to be mysterious individual who proved numerous times his loyalty to the demon lord. Not many knew how he looked due to how reserved and quiet he was. Those who knew always had one thing to say when describing him: he was the second strongest demon to ever live.

However, this changed one day when he vanished from the face of the earth. Or rather, was not heard from for a while. It was not common to encounter Uppermoon demons, but this silence had puzzled them. The demons believed that he was simply occupied with his own thing like the other Kizuki demons were. Though some rumours had began to spread.

Had he died to a Hashira? Unlikely. Had the sun burnt him up? Also unlikely; he was neither foolish nor blind. Had he betrayed his superior and all demon kind? No way. Was he busy to find the blue spider lily? Or was he trying to find the headquarters of the pesky demon slayers? The latter questions were the most likely answers that even had the demon lord convinced. No one would dare presume that his right hand man had disappeared lest they earned his wrath.

The theories were reasonable to a degree, but they were far from the truth. All apart from one. The demon in question was lying down on a futon in the living quarters of that small, wooden house which was basking in the warmth of the setting sun.

Uppermoon One had gone rogue a long time ago, and no one knew it yet.

When Kokushibou requested to be [Name]'s companion, he knew that dedicating himself to follow a human like her would make him stronger and give him the unexplainable thrill he felt after centuries of mindless killing and servitude. With that, he hoped that one day he could overpower her at last.

If Kokushibou could be honest, he was a demon who held pride in his strength. The fact a human, much more a foreign woman, could defeat him with little to no effort made him taste bile in his throat. Despite wanting to feel the thrill, he wanted to know more about her abilities, especially her weaknesses.

Was anyone really surprised? Not really, and she knew it.

The first few weeks, the demon came to realise sooner that [Name] was always on guard. One time, he had approached her from behind while she was writing in her notebook using a pen that he presumed to be a Western design. For a tall demon like him, he had an uncanny sense to appear and disappear without being detected. The startled [Name] had gripped the pen in her fist and stabbed him in his abdomen.

To say she was apologetic was an understatement, even though he had barely reacted to the glaringly obvious pen sticking out of his torso. 'She never lets down her guard.' Kokushibou could respect her high sense of instinct and waved the incident aside. His curiosity would go unsatisfied about the contents of the notebook.
