Plot Summary[]

A series of terrorist attacks that destroy famous landmarks begin happening around the world.

Episode Recap[]



  • "Baron King" is a loosely modeled adaptation of the character Van Vogt, which makes sense given this is an adaptation of the Yomi manga arc he was the main antagonist of.
