Their response to my report.
I also asked about demonic cores from Ragnarok not having anything to exchange. They seemed to have just ignore that entirely.Dear Gamer,
Thank you for your interest in Kamihime Project.
The event shop is set in a way that new players can exchange event items at the same price as the those playing for the second time.
Players that have already played the event the first time have a chance to buy even more items, though at a higher price.
Thank you for your kind understanding and continued support.
Sincerely,
Kamihime Project Development Team
