Quest of Lost Memories: Otome is a Japanese anime MMORPG developed by Level-5 and published by The Online Entertainment System. It was released in 1997 and has been re-released in digital versions for mobile devices. In the game, the player wakes up in a strange place with no memory of how he got there or what he is doing. He is a character named Tomioka Giyuu, and the only thing that he knows is that he is a character in a game called MMORPG. He is not sure how he got there, but he does know that he has a lot of friends and that they are all characters in the same game. He also knows that he has a special ability, and that it is connected to his brain. This is the reason why he has no memory of his past.

In order to find out what is happening and who is involved in this strange game, he has to find out the source of the virus that is in the game. He is not sure how to do that, but he knows that if he does not do that, then he will be infected. In order to avoid being infected, he has to stay in the game.
