Training in the Spiral of Hell

Tokkun!! Rasen jigoku (特訓!! 螺旋地獄) is the 129th chapter of the manga and the fifth chapter of the Ultimate Weakness Moxibustion Arc.

Cologne begins teaching Ranma the steps to mastering the Hiryū Shōten Ha. First he must draw his enemies in towards him while staying within a spiral pattern. Ranma finds this difficult to do when Genma keeps showing Akane and Ukyo nude pictures of him. The next morning Ranma finally manages to stay within the spiral pattern and finishes the first part of his training.

Continuing from the Previous Chapter
Still in the Yomogi Valley, Cologne requests Ranma gives her his analysis of the Hiryū Shōten Ha. Ranma recalls Cologne's comment about the stronger the opponent, the stronger the blast will be. He continues by saying that when they attacked she just dodged them, making them think they were closing in on her, when instead she was drawing them into a single spot before using a single strike she managed to blow them all away.

Ranma then grabs a stick and draws out the steps of the Hiryū Shōten Ha, which he reveals form a spiral. Cologne is impressed that Ranma noticed this after only one demonstration and continues by reaffirming that Ranma is correct as the essence of the technique is to draw your opponent inward within the spiral. Ranma then tells the old ghoul that he'll master the technique by morning, although Cologne quietly suggests that it would be that easy...

Later On
When Cologne returns to the tent where the others are waiting, she tells them that Ranma will need their help in order to master the Hiryū Shōten Ha. After Ukyo notes her willingness to help Ranma however she can, Cologne informs them that Ranma must also learn something more important than just the spiral steps. She then turns to Genma and tells him that, even though he's Ranma's father, he must abandon all sentiment and become an ogre.
