Ran Luckmolde

Cold and cynical, it's hard to tell who is more frigid--Heigar or Ran. This 17-year-old girl is the third and last female member of the mostly-boys Zwei class. Ran develops some kind of attraction for Pat Campbell, even though he is half her age and prefers Ginny and Juli's more open company to Ran's. This attraction becomes apparent as the series goes on despite Ran's attempts to hide it. Indeed, it was insinuated by Heigar that Ran's emotions concerning Pat bordered on shota-con.
