In order to understand the changes on Vivillon related to its scale powder, Yuga spent over a month researching and conducting experiments.
However, Pokémon, these magical creatures, are incredibly complex, and understanding them isn't easy, especially when dealing with unique individuals like Vivillon.
Yuga isn't a professional Pokémon researcher and isn't skilled in scholarly work, so despite his efforts, he couldn't make much progress in his research.
But when he thought of Pokémon researchers, Yuga remembered Professor Birch. Perhaps Professor Birch would be interested in the changes on Vivillon.
With this in mind, Yuga thought it was a great idea.
He had met Professor Birch through Mr. Norman and had resolved the issue of his Magikarp not evolving with the professor's help.
To thoroughly uncover the secrets of Vivillon's changes, Professor Birch might be more knowledgeable.
However, before Yuga could contact Professor Birch, he received an invitation letter from the Aroma Day Care.
The Aroma Day Care is a partner of the YoYo Day Care and the largest customer for Vitality Pokéblock.
This Day Care primarily focuses on nurturing Grass-type Pokémon and has maintained a good and stable relationship with the YoYo Day Care.
The sender of the invitation letter was a familiar figure from the YoYo Day Care, Hatsuki. Hatsuki is responsible for overseeing the collaboration between the YoYo Day Care and the Aroma Day Care.
The purpose of the Aroma Day Care's invitation was for a Day Care Pokémon Exchange Conference.
This is an unofficial event and operates on a membership basis, with participation limited to well-known Day Cares from various regions.
Day Cares like Reggie's Grandpa Blue Sky Day Care or the now-closed Truly Adorable Day Care do not qualify to attend this conference.
All the participating large Day Cares in this conference are private ones, and they do not invite Day Care, Nurseries, or Pokémon Day Care Centers affiliated with the League.
If the Day Care Exchange Conference held every three years is an official League event, open to all Day Cares, then the Day Care Pokémon Exchange Conference is an event exclusively for private Day Cares.
Both League-affiliated Day Cares and private Day Cares can sign up for the Day Care Exchange Conference.
When it comes to the Day Care Pokémon Exchange Conference, only private Day Cares, particularly those that are well-known from various regions, are eligible to participate. This is what is known as a membership system.
It's evident that private Day Cares are more exclusive compared to the League-affiliated ones. They not only exclude League-affiliated Day Cares but also smaller ones.
However, this exclusivity can be understood to some extent.
Compared to the Day Cares operated by the League, private Day Cares have relatively lower competitiveness, which is why they tend to form alliances.
Yuga had heard about this Day Care Pokémon Exchange Conference a long time ago, but he felt that YoYo Day Care wasn't at the level to participate in such an event. Unexpectedly, he now received an invitation from the Aroma Day Care.
To become a member of the Day Care Pokémon Exchange Conference and be invited, one of the conditions is to receive an invitation from one of the longstanding member and gain recognition from the other three member.
The Aroma Day Care is one of the oldest member with a rich history, making them eligible to invite YoYo Day Care.
Before sending the invitation to YoYo Day Care, they also secured the support of the other three major Day Cares.
On the invitation letter sent to YoYo Day Care, Yuga saw the names and emblems of the other three Day Cares that supported YoYo Day Care's participation in the Pokémon Exchange Conference.
These three Day Cares are the Frosty Shine Day Care from Sinnoh, the Aurora Day Care from Kalos, and the Meow Meow Day Care, also from Kalos.
To be honest, although these three Day Cares are well-known, Yuga isn't familiar with any of them, and he can't quite figure out why they would support YoYo Day Care.
However, Yuga quickly discovered the answer.
Both Frosty Shine and Meowth Day Cares are partners of the Aroma Day Care. Aroma Day Care wanted to invite YoYo Day Care, and out of goodwill, both of these Day Cares expressed their support.
But as for why Aurora Day Care did this, not even Aroma Day Care knows.
According to what Hatsuki revealed, Aurora Day Care, upon learning about Aroma Day Care's intention to invite YoYo Day Care, proactively contacted Aroma Day Care and expressed their willingness to support YoYo Day Care.
Aurora Day Care's scale and reputation even surpass Aroma Day Care in the Hoenn region, making their proactive support for YoYo Day Care somewhat perplexing.
Regardless of their motives, as long as it served their purpose, Aroma Day Care had no reason to refuse their support.
Although Yuga was curious, he soon put this matter aside. Whether they had good intentions or ill intentions, YoYo Day Care was not to be underestimated.
Speaking of the Day Care Pokémon Exchange Conference, the name itself suggests that it's an event where major Day Cares exchange resources.
When it comes to Day Cares, the core focus is always on nurturing Pokémon.
But breeding Pokémon requires breeding seeds, so the Day Care Pokémon Exchange Conference serves as a place for Day Cares to exchange what they have.
All major Day Cares have their signature Pokémon, such as Aroma Day Care's Cacturne and Lotad, and YoYo Day Care's Trapinch and Gligar.
Even with their own signature Pokémon, major Day Cares still make efforts to nurture other Pokémon.
Private Day Cares lack the deep resources of League Day Care Centers, so if they want to nurture other Pokémon, they have to collaborate with other Day Cares, leading to the creation of the Day Care Pokémon Exchange Conference.
However, it's rare for a Day Care to exchange their own signature Pokémon since these are their trump cards for survival.
Yuga was delighted to have the opportunity to participate in this Pokémon Exchange Conference.
Perhaps at this conference, he could find partners for his Vulturna and Mandibuzz, or even introduce some new Pokémon to YoYo Day Care.
So, upon receiving the invitation, Yuga promptly replied to Hatsuki, confirming that YoYo Day Care would participate in the Pokémon Exchange Conference.
According to the invitation letter, this Pokémon Exchange Conference is to be held in the central city of Lumiose in the Kalos region.
The Day Care Pokémon Exchange Conference is a large-scale event for major private Day Cares from the entire Pokémon world, so the choice of location in Lumiose, one of the top cities in the Pokémon world, is fitting.
Kalos is quite far from Hoenn, and Yuga has never been there before, so he's looking forward to this trip to Kalos.
Due to this upcoming conference, Yuga temporarily set aside the matter of contacting Professor Birch and focused on preparing for the conference.
