明治東亰恋伽 トワヰライト・キス

When the protagonist- Ayazuki Mei from present-day Japan- warped through time, she had arrived in a strange Meiji Era "Tokyo" in which mononoke exist.

There, she met Mori Ougai, Hishida Shunsou, Kawakami Otojirou, Izumi Kyouka, Fujita Gorou and Koizumi Yakumo, who are famous historical figures. As she spent time with them, Mei realised that she possessed the ability known as "Tamayori", which enables her to see mononoke.

The days passed on by, and Mei became attracted to one of the men. She then fell in love... She was then faced with a conundrum: to stay in the Meiji Era or return to the modern era she had come from. Mei decided to stay in the "Meiji World" to be with her beloved.
