The information after slash is the company or studio that the illustrator works for, so the category would be both the artist and the company/studio together. Other TCG that credits their illustrators usually doesn't include it unless the illustrator only provide the company/studio name for credit like Gatasia Artist Studio (GATASIA絵師工房).
