I've decided to include Konatsu in a fanfiction I'm working on, by
the way the story seems to be taking shape it looks like he may play a
somewhat important role.  Unfortunately information about him is scarce and
I'm not really well versed with him either.

Konatsu is very feminine. He was raised as a female, and thinks he is a
female. He's also like Cinderella - treated like a slave by his step
family, after his mother died. (I guess his father is dead, too...)
Unfortunately for Konatsu, his 'handsome prince' was Ukyou who treats
him just a little nicer than the step family - she PAYS him to work for
her! (A whole 5 yen! Wow!) And I guess he lives at Ucchan's, because you
see him eating with her.

Konatsu's only got silly moves, no real attacks or anything... a nice
kiss attack, though.

Konatsu also, since he was basically a slave for most of his life, is
rather stingy with things - like making onomiyaki with little topping,
or really small okonomiyaki, etc. But Ukyou told him not to be, and he
went the other way - giving away money, basically. So he has no idea
about anything than being a slave, and doesn't realise that Ukyou's
ripping him off or anything.

Konatsu's basically a nice person who is way too innocent for his own
good and he puts up with too much crap from others, too.

        Also, does anyone know if Konatsu knows about the various curses?
Mousse's in particular.  What is the legal drinking age in Japan/Nerima
whatever?

He's seen Ranma change, I think... and unless something happens in manga
37, then he doesn't know about other curses.

Kun-chan...
