Angst? What Angst?: Averted. Characters react far more naturally and are scared or down when appropriate,but there's no excessive angsting around.
Crossover Ship: Due to mixing both series, many ships are this. Ranma/Ami of course. Mu-Tsu/Makoto also seems to go that way.
As of Chapter 26, there is a possibility that Akane could get together with Ryo Urawa.
Damsel Scrappy: Very much averted. Akane and Usagi were pretty bad for this in canon. Here, they both are very capable of defending themselves and are not stupid enough to be lured into obvious traps.
The one time where Akane did get overpowered and taken hostage by Konatsu's ugly step-family, she's livid at herself for getting into this situation, although she admits being threatened with having all her bones broken made it a little less shameful.
Neutral Evil: Clearly Happosai's alignment. Happosai is here monstrous in that his caring for no one but himself it taken to its logical conclusion. His willingness to do whatever it takes to get what he wants, regardless the consequences, is shown in its whole nastiness.
What an Idiot: some of the sillier aspects, challenges, or events are rightly mocked as the result of people being stupid.
Akari's grandfather's declaration of "To date Akari you must defeat a Sumo Pig in combat" leads to him getting mocked all over the countryside (not to mention the trouble with hospitals and the police).
Pantyhose Taro's mom claims that Pantyhose should love and honor his name and Happosai, since Happosai was the midwife for her. Unfortunately, Happosai then decided to bathe the boy in a cursed spring that turns him into a horrible monster and gave him the name Pantyhose Taro. Taro's mom then spread the name and how awesome Happosai was all around their home village, rendering him a social pariah. While Taro tries to defend his mom (because she's, well, his mom), even he admits that once it's put to him that way that there might be something to the neighbors staying far away from her.
Ryu Kumon's dad decided to practice the scroll that Genma gave clear warnings on as "This technique is very dangerous and is designed to break things," within the Dojo he lived in. The Dojo subsequently collapsed on top of him, killing him instantly. Ryu compounded this error by then trying to seek vengeance on Genma, blaming him for his dad's death (even though Genma openly proclaims that it was Mr. Kumon's own fault, and for once, he's not trying to weasel his way out).
Xian-pu has lots of anger thrown her way for giving Ranma the Kiss of Death, since the last time it was used it basically condemned the Amazons to a slow cultural death.
Win Back the Crowd: Years of stale by-the-formula stories have left the Fuku Fic a dead field. Judging by the reviews, many see this as a breath of fresh air in this kind of crossover.
