User blog comment:The King of the Monsters/Godzilla and Gamera crossover book!/@comment-831485-20160517020237

Like A LOT of Japanese-produced crossovers, the direct interaction between the two separate properties is nearly non-existent (seriously, is copyright rules THAT bad in Japan?), but there's enough here to make it an honest to goodness crossover, and this tidbit made my week - thanks for sharing!
