Akane Guesses the Secret!

Soshite kenin wa kieta (そして拳印は消えた) is the 145th chapter of the manga it is also the fourth and final chapter of the Mark of the Gods Arc.

Ranma catches up to Akane and finds her shocked at what happened. Ranma thinks she must have poured hot water on P-chan and found out that he was actually Ryoga. Akane explains that when she tried to wash P-chan with the hot water, he latched onto the kettle and drank it all. Ranma finds Ryoga and explains that he might have found a way to defeat him

Continuing from the Previous Chapter
After searching high and low for Ryoga, Ranma arrives at the Tendo Dojo where she sees Akane staring in shock at the empty and bandana lying on the floor. Ranma then immediately turns to Akane and asks her what happened, prompting Akane to explain that she was trying to was off P-chan's doodle on his stomach...

Before Akane gets chance to say another word, Ranma decides that Akane must've poured the water onto P-chan and now knows about Ryoga's curse. In an attempt to reassure Akane, Ranma tells her that she knows it must have been a shock but adds that Ryoga never meant to hurt her. As Ranma says this, however, Akane asks just what Ryoga has to do with this and reveals that when she tried to pour the water onto P-chan he puts his mouth on the spout and proceeded to drink all of the water.

Curious, Akane asks Ranma what this has to do with Ryoga, but Ranma is extremely hesitant to answer.

Some time later and when Ranma (who's since turned back into his male form) finds the bloated P-chan, he pours some hot water onto him to turn Ryoga back into his human form before telling him how lucky a moron he is. Ranma then informs Ryoga of his theory, much to Ryoga's excitement.

Ranma's Theory
Elsewhere, Akane hangs around in the garden when Kasumi appears and asks if she can help her as they're doing something today...

Ranma and Ryoga, meanwhile, have just walked into the training hall, which has a handily placed curtain installed. As they go behind the curtain, Ranma explains that to Ryoga that while he's standing there isn't any opening in his defence, however, when he crouched to hit back the volleyball to the "incredibly graceful and beautiful" girl it created an opening. Ranma tries to continue to reveal the meaning of all this, but Ryoga ends up hitting Ranma as he just realised that he was the volleyball girl all along.

Getting back on topic, Ranma tells Ryoga that by crouching he changed the shape of the mark, therefore, by changing the mark's expression, Ryoga will no longer be invincible which will allow Ranma to defeat him like usual and cause the mark to disappear.

As Ryoga bends from side-to-side in order to try and distort the mark, Ranma goes in to try his theory, but is easily defeated by Ryoga once again.
