Masayuki Asano is working at his father's architect office. Ritsuko is Masayuki's little sister; she is a college student. One day, Ritsuko doesn't come home. At first, Masayuki is angry, but he starts to worry about her because he hasn't heard from her for two days. Masayuki goes looking for his little sister. When he finally finds her, something isn't right. Ritsuko has lost her memory. Masayuki used to be her loving brother; now, he's just a stranger to her. They still live under the same roof, but what happened to Ritsuko? Will she get her memory back? Through many hardships, Masayuki and Ritsuko try to find the truth. What will their future hold ? This is a zapping style AVG. If you don't proceed with both his and her stories equally, you'll come up against a dead-end, or even experience a bad ending. You'll be able to remove the dead-end by proceeding with the other story. This is a bit different than other AVG games. Lots of girls will appear: 'Sumie,' Masayuki's girlfriend, 'Kyoko,' Masayuki's co-worker, 'Mari,' Ritsuko's best friend, 'Jun,' Masayuki's best friend, 'Kaori,' a high school girl, and many others. As you try to help Ritsuko regain her memory, you'll get to play with lots of babes! [From Gamelex]
