Four; The Just.
Four is very straight-laced and listens carefully to what others have to say. But her superior air masks a distorted inferiority complex. Her sexual desires match those of her sisters, but her uptight personality prohibits her from acting on those desires. She is the only virgin among the Intoners.
Five; The Desirable Five is extremely confident and greedy, she desires all that she sees, but quickly loses interest once she gets it. She purposefully uses risqué language during conversations and loves alluding to her nightly escapades. Her seemingly endless greed goes so far as to lust after her sister, Zero.
