This episode entiled Menance, its fit very well, since Joey's Trouble making Sister, Holly Jones, have return home. She look like a Rock Star and seem like sadist. Not only Holly is the problem, Agent Hugues is trying to figure out, who is the codename: Ghost(Heroman) and what the purpose that he exist.
Well I thought Holly might be a side comedy for Heroman, but seem that she have a greater role than that and the song she sang was awesome, but no info what the title of the song or who sang it. Anyway the 2 past episode was simple to solve, but the next episode will be a great battle against Minami's Robot.
