Demetrios was a young man in Ancient Greece who was a potter's apprentice, but also a rather timid otaku. Despite pursuing the arts, he was blessed with natural athletic talent. One day, he gets dragged into a village conflict. Demetrios contemplates how helpless he is, but then is struck by lightning! When he comes to, he is no longer in Greece, but a strange land where he can't understand the language and people look rather different. Yes, he somehow ended up 1964 Tokyo!
