Reigen’s everything you admire and look up to in a person. Charming, responsible, charismatic, smart, hard-working, caring, etc. He’s always had your utmost respect and admiration. That’s why you feel a bit tongue-tied when finding him working a side job at a small restaurant.

Well, it’d be less embarrassing for him if he’s just working as a waiter or a cook but no. His job is to dress up as the mascot - a cute penguin that the kids eating there adore so much.
