In "The Expression Amrilato", the main character is lost in an alternate world where Juliamo (which in the real world is Esperanto, an existing constructed language.) is the official spoken language. Therefore, while enjoying a story between cute girls, you can also learn the Esperanto language! The text in this game has been officially supervised by the National Esperanto Association in Japan.

High schooler Rin was just buying a snack in her hometown’s shopping district一but she gets a shock when her surroundings suddenly transform. "...Why is the sky pink...?" She should know this area well, but the unreadable letters on the signs and the strange language the people are speaking have made things unrecognizable. ...Just then, Ruka, a girl so cute she could be an idol, appears and extends a helping hand. Rin, a high schooler who claims to have positivity in spades, and Ruka, a supportive girl who speaks just a smattering of Japanese. This is the story, pure and sometimes frustrating, of two girls intertwined by their fumbling efforts to communicate.
