I'm energetic, I'm honorable, and I'll do my best today, too! I give my all in training, and when I eat I never leave a single delicious morsel behind. Maybe I've gotten a little taller -- you might be surprised the next time we meet.
さみしくないって言ったらウソだけど みんながいるから大丈夫 シオンの想いお守りにして ボクはいつも全開	samishikunai tte ittara uso dakedo minna ga iru kara daijoubu shion no omoi omamori ni shite boku wa itsumo zenkai	I won't lie and say that I don't get lonely... But since everyone's here, I'm all right. Thanks to the feelings in this aster amulet... I'm always at full power!

Being a tomboy is what's most natural for me right now. I think -- no, I feel -- that I want to be more like this for the city's sake. That's what fits me best, so don't feel bad, okay?

I want to become a mighty thunder dragon! Having high spirits isn't a problem for me! Is that reckless?3 I want to polish my skills and strength to protect those in trouble. I'll be like a thunderous, dancing dragon whose war cry echoes with justice! (Hyaaah!)

¹轟く (todoroku) actually has two meanings. One is "to roar", and the other is "to be well-known, famous". I went with the first one for the title, since it fits with Pao-Lin being Dragon Kid, but the second meaning fits equally well considering she's essentially a star on a reality show. (The word also appears in the first iteration of the chorus.)
²イーアルサン (ii aru san) is the Japanese phonetic rendering of the Mandarin words for one, two, and three. (Sources: Here in Japanese, and then here in English.)
³The characters written here for moumantai (無問題) don't actually make sense together in Japanese. That's because this is Chinese instead -- specifically, the traditional Chinese script for a Min Nan exclamation meaning "no problem!" (Source: Wiktionary.)^4
4I am even less familiar with Chinese languages than I am with Japanese, so if you know better than I do on this issue, I'm all ears.
