Quote:Change 123 follows Motoko Gettou, a not-so-average teenage girl.
Orphaned at an early age after the death of her mother, she was taken in
by her "three fathers," each a master of a different style of martial
arts or combat-training. Under the care of each parent, a young Motoko
was subjected to excessively rigorous training. So much was the physical
and mental strain that Motoko developed three split-personalities,
known as the HiFuMi, consisting of the ever hard-headed Hibiki, quick
and agile Fujiko, and cute and immature Mikiri, each individually
skilled in combat skills learned from each master. One day, a man begins
to harass a terrified Motoko, now in high school, as he catches her
alone down an alleyway. A classmate of hers, Teruharu Kosukegawa, tries
to help Motoko, only in time to watch as an infuriated Hibiki kicks the
harassing man directly across his path straight into a car. Returning to
herself, a shocked Motoko promises Kosukegawa she will do anything if
he doesn't tell her secret. From here poor Kosukegawa must manage a
flurry of combat fighting and ecchi madness as he is brought along for
the ride of his life into the chaotic lifestyle of HiFuMi. But what
initially developed as a friendship seems to have become more to
Kosukegawa as he longs to tell Motoko his feelings for her -- if he can
manage to survive long enough to confess, let alone find the opportune
moment. What will transpire?
