This cheeky bit of banter was taking a rather interesting turn. According to Yugi, if it was working then he was trying to bribe her but... part of this deal was that she wouldn't get to know what was coming as her reward for going along with it. It would be a mystery box or sphere kind of deal. There was a dramatic furrowing of Kimiko's brows as she began to seriously contemplate this deal of his, "Hoh? Well, I do like a mystery and while I am normally above things like bribes, I can't say I dislike anything you've given me..." she said having given it a great deal of thought. "Actually, my desire to possess all manner of things makes it almost necessity for me to accept such a bribe based on the fact I don't know what it is, but I know it can't be bad. Mystery makes it that much better!" she finally managed to exclaim. Ah, but where had this come from? What did she actually need to give him to get this mystery present? She'd all but forgotten.
Beyond this point, the 'hot pot game' apparently had no rules. It was supposedly gacha like and that made it more interesting. "That sounds like a stomach ache waiting to happen but I do understand the desire to have a whole bunch of things and try a bunch of different things at once," she said coming to that conclusion with a curt nod. Of course, she'd only recently begun entertaining more friends and more people around her in general perhaps such a game would be rather interesting with certain others in hand. "Admittedly sounds like the sort of thing that would take on a strange form of competitiveness." she finished her thought. Ah and food. Apparently the marker for general food was a good cheeseburger recommendation which she couldn't give. "Blah, that's a weird standard." she commented pouty as she could be.
The easy answer of their linked accounts was something done in the other world, but that wasn't enough for Yugi. According to him, it had to have happened early on, they did show some strange abilities with each other their shared telepathy being one such thing. Ah, had they done anything she thought of as strange? "Hm, the first week was pretty normal. There was the shared quest, the proper partying up, sharing Xerxes, staying at the Inn..." she gave consideration to their journey during that early portion. "But we only shook on deals, there wasn't much if any physical contact there weren't even any random make-out sessions!" she exclaimed. "Actually the oddest thing to happen that first week, was the constant agreement to share and physically sharing a bed, but I doubt that should count as account binding." Their early time in the other world had been spent traveling and adventuring and they'd barely acknowledged each other beyond their initial expectancies. So how did their accounts become bound?
