Furinkan High gets a new principal with some very radical ideas about student discipline and a rather unexpected relationship with blustering upperclassman Kuno.

Ranma learns what being a loser feels like for once when Happosai applies a strength-sapping technique that leaves him weak as a baby! The humiliation continues for our emasculated hero when the only way Ryoga can rid himself of the "Mark of the Gods" (actually nothing more than a martial arts calligraphy doodle on his stomach) is by losing a fight to Ranma. Fox-Fu... Cat-Fu... Flat-Frog Fu... nothing seems to work against Ryoga! Has Ranma lost his edge for good?

Ranma wants it, four martial artist pork buns from China want it, and especially Genma wants it... Described by a reluctant Ranma as the "seal" that keeps something terrible from happening, what is the "Dragon's Whisker"?

Meet Picolet Chardin II, master of the tres terrifying "La Belle France School of Martial-Arts Dining." It turns out that Ranma's and Akane's fathers - as they've been known to do, once or twice - have promised one of their children in exchange for a debt, and now that debt's come due. If Ranma can't defeat Picolet at his own game, it'd be more than "La Belle France" - it'd be wedding bells!

Ten years ago, Ukyo made a special okonomiyaki sauce - which Ranma secretly ruined. Unaware of what Ranma had done, Ukyo to this day can't quite understand why Ranma's being extra nice to her despite the phenomenal failure of her special sauce. Akane's onto Ranma, though, and one way or another he's going to pay.
