I love it when adults in anime act maturely and deal with adult problems. After witnessing the most diplomatic duel challenge I've ever seen, two dragons arrange to meet that very night to fulfill their duty. We also learn a bit more about Nataku and his clone origin story. Finally, we learn more about Karen; she's a truly fascinating character, and although she's been around since the early episodes, it's only now that we learn about her past. I adore her, and I find it captivating that she's a Dragon of Heaven despite having every reason to want the world's destruction. This episode features camaraderie, visually stunning fights, emotional dialogue, and information about several characters. It's a very complete episode.
