Izumi Jiken Files: Yukika-hen

Editor-turned-detective Izumi Kido returns in her fourth mystery. These games are known for being set in well-researched real-world environments; this time takes her to Hokkaido, the colder northern region of Japan. This entry was the first to require DoCoMo's newer FOMA 900i phones, allowing for much more advanced artwork than previous games.

This Japanese-style mystery adventure game is text-heavy and menu-driven, with players interviewing witnesses and making choices via menus. An epilogue was available on G-Mode's mobile website for players who had completed the game.
