You are right here... nothing except defend her honour, rescue her every
time some halfwit tries to kidnap her, protect her from all of the crazies,
and what does he get for it?  Not a thank you, not an apology, just a swift
trip to Tofuu-sensei's clinic courtesy of Tendou Air.

no... akane apologizes a couple of times.. well atleast one i can remember...
/quote/

Akane: Ranma.... i'm sorry... you destroyed that spring.. to save me.

Genma, Mousse, Ryouga, just about everyone cursed: YOU DID WHAT!

/end quote/

And Ranma appologises properly, for what may be the first time, near the
end of the manga.

Kun-chan...
