Virtual Hero III: La máscara del troll

The line between the virtual world and reality is increasingly thin; perhaps the excessive use of the ORV puts our protagonist in serious danger of losing the ability to distinguish between both dimensions.
After the last adventure, the relationship between Rubius and Sara has cooled. However, Zombirella's generosity, capable of putting her feelings aside, will bring the team back together to face the threats of Trollface, who, blinded by ambition, pursues the sole objective of proving that he is better than Rubius. What is the reason for his hatred?
Who is Trollface, really?
