Iyahaya Nantomo

Sayoko was just reading peacefully in her backyard, waiting for her relative Iyahaya Nantomo to arrive, when some homeless kid in a large overcoat suddenly comes in and says he’s Iyahaya Nantomo (?) and runs off. The guards catch him and bring him in, but then it’s revealed they’ve made a mistake and technically kidnapped him! So to save face the boy has to pose as Iyahaya Nantomo…or else!
