Maid nara Touzen desu. Nureginu wo Kiserareta Bannou Maid-san wa Tabi ni Deru Koto ni shimashita

For plain little Nina, working as a maid in the house of Count Mirkwood is her whole world—until a false accusation has her swept out on the streets. Jobless and with nowhere left to turn, Nina decides to set out on her very first solo journey. But Nina isn't just any maid—she's a supermaid! Her talents quickly prove indispensable to the people she meets during her travels. There's Emily, a mage who can't use magic; Astrid, a brilliant inventor whose experiments never quite work; and Tien, an orphan who can't seem to keep a meal down. Meanwhile, back at the Mirkwood household, things go awry in Nina's absence... None of them realize it yet, but Nina might just be the answer they've all been searching for. Because when this supermaid is on the job, no mess can stand in her way! (Source: J-Novel Club)
