The Alchemist
Because of the rarity of Di-Astral sense, also known as Spiritual sense, no one had it in Salmon city. Or more accurately, no one had discovered it in Salmon City.
After all, it takes certain special conditions for someone to unlock the ability to use Spiritual sense. So it was quite possible that there was someone in Salmon city who possessed the rare ability but lacked the (even rarer) opportunity to unlock it.
That said, there were alchemists from neighboring cities who took trips and for a steep price, would be prepared to refine pills for clients.
However, since they had been having such visits from alchemists and also made trips themselves to neighboring cuties to purchase those pills, they had never met an Alchemist as talented and obviously high ranked as the one that had eluded them all this while.
