Juushin Enbu/YMMV


 * Complete Monster: Shimi is a nasty piece of work, obsessed about making Taito miserable so he can unleash his Super Powered Evil Side and destroy everything.
 * * Not that Keiro isn't immune to this in the anime, he destroys entire villages for power, has his son  imprisoned and then be used as a puppet for questioning him, but his most evil acts are killing his right-hand man and turning the capital's citizens into zombies.
