"Maki Genryusai,more commonly known simply as Maki, is a fictional character in the Final Fight and Street Fighter video game series by Capcom. She has originally appeared in the 1993 beat 'em up game Final Fight 2 as a younger sister of Guy's fiancee and one of the game's protagonist characters. Like Guy, Maki is also trained in the Bushin style of ninjutsu and uses many of the same abilities and techniques.
In her original Japanese backstory, Maki is a fierce ex-leader of a youth motorcycle gang, but this was censored in the English version of the game. She was mostly well received by critics and fans alike, and remains the only original character from the SNES Final Fight games to make comeback appearances in the later titles in and outside the series, notably in Capcom vs. SNK 2."
