"Shochu is something that really, really helps with playing the bass guitar."

Or at least, it helps Kikuri. The two most important things in her life are booze and her bass guitar, and if she's scared she won't be able to do one, she's going to try to lean heavily toward the other.

And, of course, in addition to being an alcoholic who is genuinely upset about her situation, Kikuri is also a complete and total drama queen. So the moment this young(?) giant cat lady implies that she'll help the bassist get some liquor, Kikuri insinctively starts playing up her distress. She looks up at the larger girl with big, watery eyes, pleading.

"Maybe there's some in the cafeteria... Could you go check for me?"
