Sakuyaใ"...and the god dissapeared at the same time the lunar rainbow did." Patchyใ"Hmm... And she claimed to be a god of marketplaces?" Sakuyaใ"Indeed..." Patchyใ"Allowing trade when a rainbow appears... What a peculiar condition. You can do business anytime you please, after all..." Sakuyaใ"It is rather strange." Patchyใ"And yet it is not all that uncommon in the world of magic. There must be a meaning to that condition. Perhaps it makes it possible to sell things you ordinarily couldn't. Ability cards imbued with copies of certain abilities, for example. However..."
Patchyใ"This card, it certainly seemed to be a magic item, but now it's just a piece of scrap paper. No matter how I stimulate it, no ability activates." Sakuyaใ"Is that so? How strange, I am certain that they worked when I was fighting with them..." Patchyใ"And the magic imbued in the cards are all the same. I can't imagine how the cards would contain different abilities. Which would mean that... It was all your imagination..." Sakuyaใ"I haven't lied." Patchyใ"...... I know. You're not the only one talking about the cards' abilities after all. If that's the case, then there's only one possibility. It's that marketplace god's power. The secret lies in the trade with the predetermined rules."
Patchouli soon separated the ingredients of the cards, and found out that one of the components are dragon gems. Upon hearing that, Sakuya remembered... That fight that she endured in the suffocating Rainbow Dragon Cave, up on the mountain.
