This chapter opens in a palace above the sea of clouds. It's just like a fairytale, says Nemo. He's totally humiliated by the fact that he has to fight a girl who's not even his age. The girl is a ten-year-old boy named Nemo, and he's still a kid. Nemo says that the girl's name is Natsumi, and she lost to Nemo at the school fair. He says that he respects her just as much as he does, because she's a girl from a different part of the world. He asks the girl if she'll come with him, and the girl says that she will. Nemo asks why he needs to fight with a girl he doesn't know, since he thinks the girl is scared of him. He also asks why the girl didn't tell him about Rakan's story when he first heard it. When the girl asks why, he says that it's because they need a pactio, which is like a pact between two people who don't really know each other. He wants to know why Nemo is so high-spirited, but he can't figure out how to answer his own question. He tells the girl that his family's rule is that no one can surrender their lips to anyone weaker than they are, and that's why he wants to fight. He then asks if he can hold back, but that if he loses, he won't have the courage to do so. Nemo is shocked that he hasn't been told.
