Mephisto's only acknowledgment of Mittelt was a quick glance in her direction before he focused back on Junichiro once more.
Mittelt was simple to sense and figure out, Junichiro was not. Thus Junichiro was the more interesting individual for him to pay attention to. Mephisto let the silence drag out until it started to become uncomfortable, "I see.
Well, we have only been back in London for about three months. It doesn't surprise me that the lazy crow at the top of your organization didn't see fit to inform his underlings of it. Normally, I honestly wouldn't care in the least about a little two winged crow and her current toy visiting the area."
Here his eyes narrowed, "However, the vehicle the pair of you were in was quite... intriguing. The stealth abilities of it are quite impressive. If you hadn't flown so close to my location and sat still for so long, I might never have even noticed your existence.
Even more interestingly, it doesn't seem to use any of the known magic principles that are required for humans to use magic." Mephisto's grin turned predatory, "I've only seen such things once before. Who ever would have guessed that the ever illusive 'Artificer' to be such a young human child?"
Mephisto's grin only widened when Mittelt jerked slightly in surprise, even while Junichiro didn't seem to react to being found out at all. Honestly, Junichiro had expected something like this from the moment that they'd been approached by the mage back at Big Ben. He highly doubted someone like Mephisto would 'invite' a trespasser to meet him personally. Rather, a lower ranked member of the organization was much more likely to be responsible for such things.
Junichiro calmly slid his hands into his pockets, which were expanded spaces containing a plethora of interesting toys, and casually shrugged his shoulders. He was doing his best to give off a laid back attitude while trying not to freak out.
He didn't have any fear of Mephisto killing him, what little he knew about the guy implied that wouldn't be an issue. It was more likely that Mephisto would offer him a place in his organization. Which wasn't tempting in the least. Human magic sucked.
"Not a bad deduction. Did you invite us here for a meet and greet, or did you have a request? If it's the latter, I am still on vacation and won't be done with it for at least another week or two. Even then, I've got a bit of a backlog."
If his business wasn't so... unique, Junichiro would likely have a lot of pissed off customers with him randomly taking a vacation for a few weeks. However, unless there were special circumstances, he never gave a solid deadline on a project and did them by how he was either feeling, or what seemed more interesting to him at the moment. It was standard to warn customers that their orders could take months to get made.
"I was actually wondering if, perhaps, you might be interested in joining Grauzauberer?"
Junichiro rapidly shook his head, "No way. I greatly dislike standard human magic. Way too much effort for way too little results. I'm way more interested in getting my hands on Devil magic, to be frank."
There was no hiding Mittelt's sudden look of shock as her head whipped around to stare at Junichiro with her mouth agape. Who could blame her? Despite Azazel's well known desire for peace among the Abrahamic factions, or even with other pantheons, they were still technically only in a ceasefire.
The wrong thing happening could easily see hostilities breaking out once more. If Junichiro joined a Devil, they would automatically become enemies.
Mephisto's smile became more amused, "Oh? Are you perhaps hoping to join my peerage? Tannin could use a... kohai, I believe is the Japanese word."
Junichiro immediately shook his head in denial, "No thanks. I got my eyes on someone else closer to my age."
"Oho? Closer to... I see." Now Mephisto definitely looked predatory, "So it's either Gremory or Sitri you're interested in. Yes, I can see the appeal they might have for a young man such as yourself. Though, if you know they're coming soon... You must either live in, or very close to, Kuoh."
Though Junichiro didn't outwardly react, he was silently berating himself for running his goddamn mouth once more. Was there something about being in front of super powerful entities that just made his brain disengage and let his mouth run free with information that he should really keep to himself?!
Of course, his lack of outward reaction wasn't helped by the almost panicked look on Mittelt's face. Even with Junichiro doing his best impression of a wall, her reactions were giving everything away. Which one of them was supposed to be the older, more experienced one, again?
Mephisto laughed lightly and clapped his hands together, "Yes, yes! I see. How entertaining." He spread his hands and gestured to the chairs nearer to himself and the fireplace, "Come, sit, sit. I haven't had this much interesting conversation in quite some time. I would love to get to know 'The Artificer' and his traveling companion a little better."
Junichiro calmly walked over and took the seat that was almost directly across from Mephisto. He wanted to keep the ancient devil within his sights.
Mittelt sat alone on the love seat. Once they settled in, Mephisto snapped his fingers causing a spell circle to appear on top of the central table. A tea set, finger sandwiches, and assorted small snacks rose from the circle. Mephisto leaned toward the setting and fixed himself a cup of tea, "Please, help yourselves."
Junichiro didn't hesitate to mimic Mephisto in making himself a good cup of English tea. In his previous life he'd been more of a coffee drinker. His tastes had changed a little, likely due to his young age, and he found himself preferring the various tastes of different teas. Though finding a good sweet tea that wasn't made from green tea or some random ass fruit flavored tea was a pain at home. He also selected a nice looking finger sandwich to munch on.
Some might be concerned with the possibility of poisons or potions, but that was pointless. Not only was Mephisto strong enough to trounce both of them, but Junichiro was pretty much immune to poisons now.
After taking a sip of his tea and smiling at the delicious flavor, Junichiro addressed Mephisto, "So, you just wished to talk?"
