I took firm note of Elise-san's advice and the next day, I immediately started contacting the big shots... those who were likely to cause a big ruckus when they went to my stall that day.
Although Kuro was brimming with the intention to come, her hobby was walking around the world eating various dishes, so she properly knows the necessary measures like Recognition Inhibition Magic.
As for Isis-san, I confirmed with her that Spica-san... the Spirit of the Blue Crystal Flower who was her new subordinate to come and buy it with Eul.
I heard of Spica-san's existence from Isis-san, who told me about her through hummingbird, but this would be the first time I would meet her in person, so I'm curious to know what kind of person she is.
When I contacted Megiddo-san in advance, he replied with "Ahh? Is that so? Then, I'll have Bacchus or Ozma or whoever's available to buy it". From the tone of his response, I could tell that he had planned to come without particularly thinking about it at first, so I was really glad that I had taken Elise-san's advice.
It seemed that Lillywood-san didn't really plan on coming because she doesn't eat or drink in the first place, and Lillywood-san, who had deep connections with Symphonia Kingdom, would be reasonably busy with the ceremony and didn't seem to have time to get out of it.
However, since it would apparently be a bit strange for her to be the only one different when all the other members of the Six Kings were going to my stall to buy my baby castellas, she jokingly said that she might send one of her subordinates, so there's a possibility that one of the Seven Princesses will come.
Magnawell-san seemed to be planning to visit with his clone body. There's almost no one who knows that the person in that body is Magnawell-san, and if you combine that with Recognition Inhibition Magic, there seems to be no problems at all.
Among the Four Great Demon Dragons, Frea-san also seemed to be interested in visiting, but it seems that she might come separately from Magnawell-san.
As for Alice... She kinda looks really prepared to act as the stall's mascot. I don't believe for a second that that exquisitely creepy stuffed costume has the ability to draw in customers... but well, if any sort of trouble happens, it would be absurdly reassuring to have Alice there, so I think it's okay.
As for the people from the God Realm, just as I talked with Shiro-san beforehand and it seems like she won't be coming. We agreed that I'll deliver baby castellas directly to her later alongside the first baby castella I made while I was making prototypes.
I also told Fate-san about my stall and confirmed it with her... and received a very Fate-san-like response, telling me "I don't want to go to such a troublesome place. I'd like to eat baby castellas Kai-chan makes though, so feed me later", so I decided to treat her to some at a later date.
As for Chronois-san, she initially didn't plan to come to the Founding Festival... but when she heard that all the Six Kings would be attending, she decided to participate because she was worried about Lilia-san, so she was going to be at the ceremony.
I felt like Lilia-san was so happy to hear that she was attending. Thinking about it again, I certainly didn't participate in ceremonies that much, and at such events, Lilia-san's standpoint was that of someone acquainted with all the Six Kings, so it's likely that she would be approached by people more often.
As for Life-san, it seems that she has no particular intention of participating in the Founding Festival or coming to my stall. However, when I confirmed things with her, she told me "If you're short on staff, just let me know. I'll send the God of Fertility to you, and you can make her work as you please" with a smile, but I felt sorry for the God of Fertility, so I refrained.
I later also checked with Eden-san just in case, and was surprised to hear an extremely decent response: "I'm interested in my child's stall, but if I go there, there will be a commotion, so I will think of a good way to do this".
It was a response so docile that I thought Kuro or someone else may have beaten her up in advance, as she even said she would give up if she couldn't find a good way.
I also contacted as many other people as I could think of, including the Six Kings' executives, in advance. Some of them said they would use Recognition Inhibition Magic, while others said they unfortunately couldn't come, but generally, it seems like there won't be any problem.
I also purchased the magic tool that Elise-san had told me about, and ordered stall utensils and other equipment from Alice. I also confirmed with Nebula that it would be okay to use her chocolates, so I made a list of ingredients and asked Shiro-san to create them for me.
And so, with preparations almost complete, I decided to go to Alice-san's store to pick up the stall and cooking utensils, and immediately start making a prototype.
I'm told that baby castellas aren't so difficult to make... but I hope they turn out delicious.
