I found it kinda refreshing that Mamoru wasn't even in this one, honestly. It was super sweet watching Usagi try to be a matchmaker, and I really liked how she actually used her brain to help Yusuke and Akiko get together, which felt like a nice change for her. And lol, her transforming into a tall, green-haired musician just to sneak into that club was such a classic Usagi move, she really goes all out for her friends even if it's totally ridiculous.
