After defeating Do-S, Sweet Mask continues to roam the headquarters, coming across more monsters and beheading one of them, taking its head with him.
Sweet Mask comes across a room with many tanks and hundreds of Monster Cells within them. The monster head explains the machine's function to Sweet Mask. The hero concludes that in order to stop the production of monster cells, he must kill Orochi, and effortlessly destroys the Monster Cell tanks.
Suddenly, Sweet Mask senses something up ahead. The voice in the hallway cackles, pleased it has finally found Sweet Mask. The hero asks the monster head about the voice and he recognises it as a cadre. The Monster Association executive nimbly bounces off the walls and the ceiling of the hallway at tremendous speed, earning the praise of Sweet Mask and beginning the battle.
Noting that this monster is an extraordinary presence, he's determined not to give away his upper hand easily, and throws the head at Fuhrer Ugly. Alas, the monster is able to easily react and kick the head up to the ceiling, permanently endings its life. Sweet Mask is amazed by the monster's swift movements, but believes that if it is a fist fight, he has the confidence. This confidence quickly fades, however, once the hero gets a good look at Fuhrer Ugly's grotesque appearance. Sweet Mask gasps, and barely has enough time to put up his elbows and defend himself from the monster's attack, sending him back quite some distance.
Sweet Mask is in a state of shock, believing the opponent he's up against to be the worst and most terrible evil, and Fuhrer Ugly strikes the hero from his left side. The monster mocks Sweet Mask, saying he came to the Monster Association knowing the danger and deriding him for his sudden fear. While Fuhrer Ugly is talking, Sweet Mask believes that even he, the handsome, highly intelligent, mighty warrior worth a thousand men, and "perfect" hero could not win this. Fuhrer Ugly identifies the hero as "Sweet Mask", and states he's the hero he hates the most. The monster says that in different ways, both of them make the girls scream.
Stating he's going to kill the hero, Fuhrer Ugly explains that looks and battle stats don't go together, and that reality is something he will carve into the precious money maker's face. Sweet Mask realizes that Furher Ugly is undoubtedly a type of Ugmon, an ugly person whose social problems cause hatred to fill their hearts until they're swallowed by darkness and turned into monsters. He also concludes that their strength after turning into monsters is influenced by the hideousness of their hearts. Sweet Mask reaffirms that this battle is unwinnable for him not only because of the monster's strength, but when the hero witnesses extreme ugliness, his entire body starts shaking and he can no longer move.
