"Eve: The Fatal Attraction" is a chapter in EVE series, and is based on the hentai PC game Adam: The Double Factor. Its scenario was expanded in this game up to the point of being a sequel to "Adam". It adds many Eve: Burst Error and Eve: The Lost One references, lots of new events, 2 more days and proper ending to the game.
You control the two main heroes of the game, the young careless detective Kojiroh and the sexy red-haired super-spy Marina. The events of the game are connected to their previous investigation (in Eve Burst Error). Kojiroh's ex-girlfriend and colleague, Yayoi Katsuragi, receives a case: somebody is threatening the life of two young girls, Mika and Miki, the daughters of the owner of the powerful Andou Corporation. Naturally, Yayoi needs Kojiroh's help, and here the investigation truly begins!
Like in other Eve games, you control two characters in two "scenarios", and sometimes the cooperation between them is necessary. The game utilizes the same "Touchable View" that was implemented in "Adam": you interact with the environment and with the characters not by selecting menu options, but by moving the cursor around and clicking on objects, like in Western point-and-click adventures.
Wild and subtle, self-titled "Super Top-Notch Detective."
A private detective. Once belonged to the Katsuragi Detective Office, where he solved many difficult cases and made a name for himself as a great detective. But a certain incident during the events of the game "EVE Zero" compelled him to leave the office behind and try making his own detective office at the dock area in a run-down warehouse, which he still owns.
He's no good at desk work, and is more adept at using his own head to investigate. His skills didn't completely decline over the time while work was rare to come by. He's rather loose when it comes to women.
A brilliant (trouble-making?) international agent. Even though she boasts a 99% success rate, she is alienated by various officials because she wreaks havoc wherever she goes. She served abroad for awhile, but has returned to Japan after a long absence. Her best friend since ages ago is Yayoi, from the Katsuragi Private Detective Agency.
