Aru Hi, Burikko Akuyaku Reijou ni Narimashite.(2015)

Aru Hi, Burikko Akuyaku Reijou ni Narimashite.

The high school girl Manami who had fallen down the emergency stairs at school had, before she noticed, become a three-year-old in the world of an Otome Game. What’s more, that little girl was one of the rival characters that appeared in the game; the can’t-take-a-hint-burikko-type-rival daughter of a marquis family. What awaited her at the end was social obliteration. Though she did get a bad feeling about this… Manami decided not to worry! It was a dream after all, so that had nothing to do with her. For now, she’s going to master magic! Hooray!

Note: Aru Hi, Burikko Akuyaku Reijou ni Narimashite. began as a web novel on Shousetsuka ni Narou under the title "Otome Game no Burikko Akuyaku Onna wa Mahou Otaku ni Natta" (乙女ゲームのぶりっ子悪役女は魔法オタクになった).
