Ultimate Weakness Moxibustion - Chapter 6

Cologne straps Ranma into a harness made of memory metal. The least amount of heat will make it contract, painfully. Therefore Ranma must be extremely careful not to release any battle aura, to remain absolutely ice cold. Cologne reminds Ryoga that he must not hold back. Ryoga attacks, and Ranma leads him in a perfect spiral. Except Cologne interrupts, whacking Ryoga over the head and calling him an idiot, telling him that she said not to hold back. Ryoga realizes the truth - in Ranma's weakened state Ryoga can't bring himself to truly attack him without holding back. No matter how much Ranma provokes him. Feeling like a failure, Ryoga runs off, with Ranma yelling for him to come back.

That night, Genma, Cologne, Ukyo and Akane are discussing the hopelessness of the situation. Cologne points out that a tremendous heat of battle is needed for the technique to work. This gets Akane thinking. Akane tracks down Ranma, who is off moping. Akane has donned some sort of gloves which she has set on fire. In her thinking, this will allow her to attack Ranma while providing a substitute for the battle aura of a true opponent. Ranma doesn't think this will work, and while they argue the fire spreads to Akane's gi. She jumps into a nearby pool of water, but her gi top has been destroyed, leaving her in her pants and bra. Ranma gives Akane his shirt.

Akane and Ranma get into a big argument, with Ranma telling her to go home, and Akane complaining that she just wanted to help, and he wants her to leave because she can't cook like Ukyo and isn't as strong as Ryoga. It finally reaches the point where she runs off in tears. Ranma, unable to stand her running off thinking the things she's thinking, stops her and tells her the truth. "I can't stand for you, of all people, to see me so weak and pathetic!"

At that point Ryoga shows up again. He sees Akane there, her own shirt gone and Ranma's around her shoulders unfastened. Tears on her face. He leaps to the conclusion that Ranma attempted to rape Akane. An absolutely massive battle aura blossoms around Ryoga, and he tells Ranma to "Prepare to die!"
