KAMON NANDABA
He runs Kamon-Mabase from the family home, fills conversations with pop-culture references and immediately becomes infatuated with Haruko after she moves in. For Naota, who is desperately trying to behave like the mature person in the room, having Kamon as a father is almost professionally embarrassing.
Kamon is not useless, though FLCL rarely allows him dignity for very long. His immaturity is part of the larger problem Naota keeps running into: the adults around him have not unlocked some secret state where embarrassment, jealousy and bad decisions disappear.
Haruko eventually tests Kamon as a possible N.O. route, rejects him and replaces him with a mechanical duplicate. Even surviving that experience does remarkably little to reduce his enthusiasm for her.

He cannot.
The result is bizarre even by Nandaba-house standards, but the important part is what Haruko learns: Kamon is not capable of giving her what Naota can.
