A decade of peace gets shattered the moment the new Tekkaman squad realizes the old war never actually ended. The real enemy isn't the Radam anymore, it's the ghosts the original team left behind, and nobody warned these kids about that cost. Blade II trades the first series' discovery-phase energy for something colder: soldiers inheriting a conflict they didn't start, fighting enemies their predecessors created, watching the machinery of heroism grind forward whether the justification still holds or not.

Ten years after the last war against the Radam ended, a new team of Space Knights forms under the leadership of Aki and D-boy. The new Tekkaman's first assignment is to defeat the Radam, but once that fight is done, the team must face a remnant left over from the past. The six-episode OVA mixes mecha action, adventure and drama with science fiction.
