<p>Ranma 1/2 2-in-1 Edition 10 collects volumes 19-20 and features story and art by Rumiko Takahashi.</p> <p>Ten years ago, Ukyo made a special okonomiyaki sauce - which Ranma secretly ruined. Unaware of what Ranma had done, Ukyo to this day can't quite understand why Ranma's being extra nice to her despite the phenomenal failure of her special sauce. Akane's onto Ranma, though, and one way or another he's going to pay.</p> <div style="text-align:center;"> <a href="https://devstore.crunchyroll.com/products/ranma-12-2-in-1-edition-manga-volume-9-9781421566221.html" onblur="this.style.outline='2px solid transparent';" onfocus="this.style.outline='2px solid #000000';" style="display:inline-block; width:180px; margin:10px; padding:10px 20px; background-color:#fab818; color:#000000; text-decoration:none; border-radius:5px; font-weight:bold; text-align:center; outline: 2px solid transparent; font-size:16px;" aria-label="Go to previous volume in series">&larr; Previous Volume</a> <a href="https://devstore.crunchyroll.com/products/ranma-12-2-in-1-edition-manga-volume-11-9781421566320.html" onblur="this.style.outline='2px solid transparent';" onfocus="this.style.outline='2px solid #000000';" style="display:inline-block; width:180px; margin:10px; padding:10px 20px; background-color:#fab818; color:#000000; text-decoration:none; border-radius:5px; font-weight:bold; text-align:center; outline: 2px solid transparent; font-size:16px;" aria-label="Go to next volume in series">Next Volume &rarr;</a> </div>
