In chapter three, Hiro and Masaki have bought a Christmas tree and named it "Hikari" . Hikari means "bright and shining" , which means that he's a bright and shining star, which is exactly what they're looking for in a kid. They're so happy that they've named him after him. Hiro tells us that the star is so bright that it's like a "big bwight . . staw !" . The kid's dad thanks Hiro for his help with the Christmas tree, and Hiro says that the kid was thinking about his name all the time, even when he was walking around. He says that his dad raised a good kid, and that's how they named him "hikari." Hiro is all, "Ha ha part you have become so adult!" , and says that this is because of what he told the kid about being able to say nice things when he sees a star. Hiro is so happy to hear this, because he thinks the kid is so cute, and he says that he can't believe that Hiro would say such nice things to him. He's so happy, in fact, that Hiro gives him a present for his "crybaby prince" : a present that Hiro has made for him.
