Sena Mori is one of the waitresses at The Cosmic Bar and Grill and the informal floor lead because she has worked the station longer than Dani and Nari. She is twenty-one, close enough in age to the other girls to be part of their friendship, but experienced enough to know the room’s rhythm.
Calm, capable, and quietly sharp, Sena notices when a table needs attention before anyone waves her over. She knows which regulars want conversation, which ones want silence, where people prefer to sit, and how to keep a busy shift from feeling chaotic.
Sena is not a manager in the formal sense, and she does not act like a boss. Her authority comes from competence, patience, and the fact that people trust her judgment.
Around Dani and Nari, Sena can be dry, teasing, and more relaxed than she first appears. She is the kind of person who remembers where the leftover birthday hats are and knows how to make the dining room feel steady.
