This interview with Legend of Valkyrie character designer Hiroshi Fujii and main designer Koakuman originally appeared in the 1/91 issue of Hippon Super, and was later republished (with additions) in the World of Valkyrie illustrated book. Fujii discusses his early days at Namco, how he got involved with the first Adventure of Valkyrie game, and his sophisticated approach to designing the characters and world of Legend of Valkyrie.
I’ve also included a large selection of Fujii’s lush concept art, much of it depicting unused characters and stage ideas that didn’t make it into the final game. I would also recommend refreshing your memory by re-reading the wikipedia plot summary of Legend of Valkyrie to get the most out of the interview.
