She later explains that she developed multiple personalities due to each of her ''[[HasTwoMommies three fathers']]'' [[TrainingFromHell Trainings from Hell]]. Yes, plural. When she is threatened, any one of the three alter-egos that split off due to the trauma of those experiences emerge and cause carnage. Because her fathers are an expert karateka, a skilled soldier/swordsman, and a world-famous Jujitsu master, they're really, ''really'' good at it. By extension, so are Hibiki, Fujiko, and Mikiri respectively.

* FuroScene: The trip to Okinawa, again.
* GagBoobs: Most of the women are already [[BuxomIsBetter well endowed]], but Mikiri just ramps it up.

''Change 123'' (pronounced "change hi-fu-mi," as a Japanese language pun[[note]]Numbers often have alternative readings when used as counters for objects. For example, the counter for 1 person is ''hi''-tori and for 2 people it is ''fu''-tari.

* GagBoobs: Most of the women are already [[BuxomIsBetter well endowed]], but Mikiri just ramps it UpToEleven.
