Real Taiwa de Manabu Jissen Eikaiwa Summer Story

A bilingual visual novel in Japanese and English for Japanese users who want to learn English.

Not only can players listen to spoken English, but they must actually speak English with proper pronunciation to advance through the game.

In the game, the player interacts — entirely in English — with three female college students who are studying abroad in Japan. The three students are Allison Lloyd (a quiet 21-year-old gardening fan from a London suburb), Charlotte Ryan (lively 20-year-old aspiring tour conductor from Sydney), and Elisabeth "Lisa" Ferguson (a 19-year-old anime fan from Florida). The character Karen M. Turner appears as the player's 26-year-old college English teacher from Yokohama.
