Ashi Girl(2017)

Ashi Girl is a Japanese romantic comedy series following Hayakawa Yui, a modern girl whose only real talent is her speed. When she accidentally slips through time, Yui finds herself transported to Japan's turbulent Sengoku Era. Stranded centuries in the past, she must navigate a world of samurai and political upheaval while grappling with an unexpected romance. Her contemporary outlook and lightning-fast reflexes make her an oddity in feudal society, leading to both comedic mishaps and genuine connection. The series blends time-travel fantasy with period drama, exploring how Yui's ordinary modern life collides with extraordinary historical circumstances. As she grows closer to someone from this distant past, she faces an impossible choice between two worlds.
