Of Pokèmon and Duel monsters

Bakura smirked. It was so nice of the weakling to suggest that he was Bakura's pet. Not that the reality could ever be anything other than horrifying of course, Ryou was his pet host and he wouldn't want anyone else to take his place, but it was still interesting that the other man had suggested it. This Sirius must not be as confident as he wanted to be if he was having thoughts like that. Then, after wandering around in the shadow realm for a while, especially since he was unable to defeat even the lowest level monsters, anyone would be scared. He wasn't going to let that stop him though.
"Perhaps we should discuss this." Bakura began condescendingly. "You're the one with magic so weak that you couldn't save yourself from the monsters in the shadow realm, and I'm the one who had to save you. Doesn't that suggest that I am your superior? You certainly cannot think that you are above me after that display of incompetence."
"That thing was like twice my height and you call that incompetence?!!!!" Sirius sputtered, looking completely shocked and angry. "What is your problem?!"
Bakura snorted. "The man-eater bug is one of the least powerful monsters in the shadow realm. It's almost as weak as the fluff ball. If you couldn't beat it then you are seriously weak. At least my host wouldn't have screamed like that. Did you know you scream like a girl?"
"I do not!" Sirius flared. "And if that thing is weak then the things in that place must be insanely powerful. How would you know anyway?"
"I spend most of my time in the shadow realm." Bakura replied, shrugging. "And the monsters are actually on Duel Monsters cards. Pegasus found out about them and decided to create a game using them like the Ancient Egyptians used to." He would have said more, as the difference between the card game and the fights between people's Ka was one of his favorite subjects, but if he started on that it would lead to uncomfortable questions. If he was asked how he knew all that stuff he'd have to tell his story, and then he'd have another person blaming him for everything. He may have been used to it but that didn't mean he liked it.
"Duel Monsters?" Sirius asked, distracted from his anger by the subject. "Isn't that the new card game that everyone's playing? The one where they pit the monsters in their decks against the other people's monsters? Sort of like the Pokèmon card game?"
"Yeah, something like that." Bakura agreed. "I never really liked the game itself that much, but I played because everyone else was, and I wanted to see if I could defeat Yami at his own game. The monsters are pretty cool though. You're lucky it was the man-eater bug you ran into rather than one of the so-called nicer ones. At least the man-eater will give you a chance before it kills you. If you'd run into the Black Magician or something like that you wouldn't have had a chance to scream."
Sirius stared at him, seemingly overwhelmed by the information Bakura had given him. "Fighting monsters is not one of my strong points."
"It's not one of mine either." Bakura replied coolly. "But it's not exactly difficult is it?"
Sirius opened his mouth indignantly to, no doubt, try to insult him, and then closed it again, staring at someone in the crowd.
"Well, well, who have we here?" mocked the black-robed man. "If it isn't the little escapee. The Dark Lord wants you, you know. Apparently you could be an asset if you were turned. It looks like getting lost has its good points."
Sirius let out a sort of laughter at this. "Like your tendency to get lost in school and conveniently turn up in the girl's bathroom?"
Bakura smirked. "If this is the type of goon that the so-called 'Dark Lord' leads I don't think there's anything for anyone to worry about. And yes that includes Muggles."
The man growled. "That's easy for you to say. You've never seen him."
"Nor do I want to." Bakura returned. "From the description I was given he's frightfully ugly. And as I have a healthy appreciation of beauty I wouldn't want to turn my stomach by looking at something as hideous as this 'Dark Lord' of yours."
