Welcome. Welcome to Muscle Bunny Bar 'Usami'.
Regarding all staff members:
Man, I used to think I was pretty big myself. But once I opened this shop, everyone turned out to be huge! I'm actually the shortest one here, can you believe it? Well, they're big guys perfect for the name 'Muscle Bunny Bar,' right? They're reliable comrades with broad backs.
Regarding Rabi:
Rabi is such a good kid. He's serious, kind, and he's even fluent in English! He's the youngest one here, but he's doing a great job. I wonder if all young kids these days are that serious. ...Wait, did I just sound like an old man? No way! I still want to stay young!
Regarding Uzuki:
He's a problem child! Always hitting on the customers. That said, I never see him getting into trouble inside the shop, and I haven't heard about him causing trouble outside either. Seems like he handles that side of things surprisingly well. By the way, how's your mom doing lately, Uzuki? She came by the shop the other day to say, 'Please look after my boy.' She's a good mom, you better take care of her.

In a manga, he'd definitely be a villain! ...Well, with those movements, he's clearly from a... no, it's bad to decide based on assumptions. Everyone has a secret or two... or maybe a hundred!
