Anime History
In episode 43 of MegaMan NT Warrior Axess, Ms. Mari reveals that during childhood, she lost her sister as a result of a unique plane incident. It occurred whilst her family decided to move to a new house, everything was ready but Ms. Mari developed a fever, which caused her mother to stay behind and take care of her. Even so, her father and sister went ahead and boarded the plane, which collided with a falling meteorite whilst airborne over the ocean. No sign of the plane was ever found, which lead Ms. Mari to believe that the familiar woman she keeps seeing, is not her sister. Ultimately, she is properly united with Ms. Yuri during Rockman.EXE Stream.

Additionally, Ms. Mari acts as chaperon to Lan Hikari and his friends on a few adventures and usually ends up caught in the thick of a situation.
