Continuing from the Previous Episode
As Akane continues to remain in shock at Ranma's change in appearance, the Niku-men discuss their latest defeat. Seeing as they can't win by brute force, the group agree to try one more plan, this time using a sleep-powder laced Red-bean bun!

After setting the trap, the Niku-men lie in wait for Ranma to arrive. Unfortunately, their "prefect plan" soon falls apart as Happosai appears and quickly consumes the bean bun. Seeing this the infuriated Niku-men swarm around Happosai, but the group are easily defeated by even the half-asleep Happosai. With them having received their worst beating yet, the Niku-men quickly apologise to the old lecher; revealing that they only did this for the Dragon's Whisker. Intrigued, Happosai asks what the Dragon Whisker is which prompts the Niku-men to huddle around him to explain it's power. Now aware of the whisker's power, Happosai decides that he must secure it for himself...

Back at Furinkan High Akane (having gotten over her initial shock) asks Ranma what's happened to him. Ranma proceeds to explain that, whilst he was training in China, she stopped a thief, but quickly ate the food he had stolen to subdue her own hunger. The owner of the food was concerned that Ranma was male, but was relieved to see that she was female. Ranma continues by explaining that after taking her back to his restaurant, the man told her that the food she ate was made with stock from the Dragon's Whisker which has no effect on women, but unleashes the true ambition of any man who eats it. Curious, Ranma proceeded to use some boiled water to change back to his male form, much to horror of the whisker's owner who offered him the Dragon's Whisker to him so that he may seal it's power until the effect wears off.

With Ranma's explanation finished, Akane comments how she can see why men would fight over it.

Genma's Revelation
Genma, meanwhile, decides to head to the Cat Café in the hope that Cologne can divulge some information about the Dragon's Whisker, but all she tells him is that the whisker causes endless strife and that even if she knew the secret she wouldn't tell him. Hearing this Genma attempts to get Cologne to reconsider, but just gets warned by Cologne that she especially wouldn't tell someone like him.

This comment intrigues Genma who begins to wonder how he would be effected by a whisker that causes wars. Just then, Genma is jumped on by a passing Happosai, declaring his want for the whisker as he passes. With even his master now wanting the whisker, Genma tries to deduce some sort of connection between him and the Niku-men and after only a few seconds Genma makes his conclusion... they're all bald! Hoping that his hunch is correct, Genma rushes off to claim the whisker before anyone else can.

Back with Akane and Ranma once more, and Akane notes the power of the Dragon's Whisker hair rejuvenation abilities. She then swiftly cuts off Ranma's elongated hair before tying together with the whisker again before it has the chance to grow back.

As the pair walk out of school, Akane asks Ranma if he's worried about the Niku-men attacking again, but Ranma retorts that he isn't worried about them. At that moment the two of them come under attack by a barrage of Happo-Fire Burst bombs. Fortunately Ranma manages to grab Akane and evade the attack in him, but as the smoke clears the pair see Happosai standing in front of them, surrounded by his Battle Aura. With Ranma unwilling to hand over the whisker, Happosai attempts to take it by force, using his aura to send Ranma flying before launching another Fire Burst bomb. However, Genma suddenly arrives and grabs the bomb before throwing it back to his perverted master.

Genma's act of insubordination infuriates Happosai who goes in for another attack, only for Genma to declare he won't let anyone hurt his son anymore before proceeding to finish off his master with a single punch. Now that his master has been dealt with, Genma turns to his son and asks if he's okay, only for Ranma angrily exclaim that he hopes he's not after the whisker too. This claim (although true) hurts Genma deeply, who immediately proceeds to run off in tears.
