Lila is a maid who has served Mayor Maybelle for a long time. She was originally born and raised in Leman State where she went by the name Rennie, and was on vacation with her family to Liberl just before the Hundred Days War. She lost both her parents when the Erebonian Army attacked the City of Bose and bombarded the Market. Initially in such a state of shock to where she couldn't even speak Rennie was rescued and taken in by then Mayor of Bose and his daughter Maybelle and given the name Lila.
She acts as her bodyguard, assistant and caretaker and is not afraid to reprimand her boss from playing hooky from her work. However, she offers nothing but praise about her boss when asked.
Lila is a very solemn girl. She is very serious and dutiful to her duties as a maid. However, she doesn't emote much and often seems depressed about something.

Insulted, Lila tells the two that she will the mayor about "everything" they have said and asks them to leave.
Once the pair leave, Lila sighs. She then sees Estelle and co who ask her "What's wrong?" In response, Lila vents to the two about the pair; calling them 'miscreants' and other stuff and vows to protect her mayor. Joshua notes how serious she is to her job and Lila states that she is.
