You made your own? That's pretty impressive. I hadn't figured on looking into it much before, but I do want to be able to help Kacchan when he gets his new arm. So, I want to learn what I can. Anything that might help me to be able to support him. Maybe figuring out how to help him with some simpler maintenance?

[Still, the boy tilts his head as the other shows his arm. And then mentions the music club.]

There's a club? I just know Kacchan mentioned he was in a band. I listen to music sometimes, but it's not like I'm an expert, or that I know about the theory and stuff. So I thought I might try to learn more.
