Flame in the Mist

Flame in the Mist most closely resembles Rurouni Kenshin fanfiction, except for some samurai anime I didn't watch.
Mariko is the super special Mary Sue. Her twin is an awesome samurai, her betrothed is an awesome samurai, and the two hot guys she ends up hanging out with are awesome ronin. In a story of samurai, she single handedly invents the ninja. Seriously, she invents the shuriken and smoke bomb in the span of a month.Pigeon Japanese is sprinkled throughout the dialog along with cultural trivia like what kind of socks they're wearing or tea ceremony in excruciating detail. The sort of thing you'd expect from fanfic.
