Illustrator Comment:

“A theme combining the twelve zodiac signs and western fantasy. I remember being overly anxious about feeling that if I didn’t hurry up and finish the illustrations, they wouldn’t be able to allot for all 12 of them. I think I drew way too many variations for the hairstyle of Ratpier. Bunnyblast was designed to completely flip her personality while firing her weapon, and at the time this had to be conveyed only in a Spell Card, so I made sure to emphasize it to the extreme, but now that I look at it, she looks super scary, doesn’t she.”
