"[Azusa] likes potato chips, roasted sweet potatoes, baked potatoes with butter, and practicing." – Excerpt from the Hibike! Euphonium wiki, information translated from the official Hibike! Euphonium novel website by Tekketsu08.
"I wonder how Azusa's doing right now…" Kumiko mused. "Ever since she got that invitation, I haven't heard from her at all. Not even a phone call or a text message all this time… I really hope that she's all right wherever she is."
"Azusa? You mean Azusa Sasaki from our middle school? The one who played trombone in concert band?" Reina asked, to which Kumiko nodded her head. "If it's her, then there's nothing to worry about. While I'm sure I don't know as much about her as you do, I have complete confidence Miss Sasaki can handle any challenge coming her way. That's the type of person she is."
"How are you so sure? You just admitted you don't really know her that well." Confused by Reina's contradictory statements, Kumiko was still intrigued by Reina's old declaration. "Should I tell you more about her before you actually say that?"
"I would most definitely like to hear about Miss Sasaki, but there's a reason I'm so certain." Reina clarified. "She's an extremely driven person just like myself, so as long as there's a goal for her to strive towards, Miss Sasaki will stop at nothing to achieve it!"
