Parental Sexuality Squick: Averted. Not only she's perfectly aware of her parents' sex life, she is actually quite comfortable about it. It's the thought of Speedor and BearRV having sex that freaks her out.
Quirky Household: Even if the Go-ongers other than her parents and Hiroto aren't related to her, Hibari treats them as if they were — going as far as calling Renn her "grandmother" — and loves them with all her heart.
Eerie Pale-Skinned Brunette: Her hair is a very dark auburn rather than black (although she does get a black Horned Hairdo when she transforms) but in either civilian or Cure form, she qualifies. She's really nothing but nice.
The Nose Knows: Kaori loves perfume, and wants to become a perfumer someday... unfortunately for her, her father's odd violin varnish ingredients tend to disagree with her sense of smell a lot. In fact, the one time she truly got angry at Wataru was when she discovered he used a carrion flower in one particular batch.
Personality Blood Types: Just like Hibari, Kaori's blood type matches her father's actor's — Koji Seto carries a type A. (However, it's subverted in that this was actually coincidental.)
Hibari / Cure Velocity's Engine partner and, if you can call him one, "mascot", as well as Speedor and BearRV's son. Mostly the same as he was in Kaizoku Sentai Gokaiger, but older and with several modifications.
Kaori / Cure Fangoria's fairy partner, who came from the future to help her fight against the Neo-Fangires. His species is actually a future divergence from the Kivat race.
Bat out of Hell: Subverted — while he almost looks the part, he's no more threatening than his bretheren in the end.
Deadpan Snarker: Name something, anything, and he will have some kind of smartassed remark about it.
Fastball Special: Fangoria uses him in her Barnabas Bullet attack, similar to her mother and Engine BearRV's Bullet Crash.
Jerk with a Heart of Gold: Despite the fact that he likes to gripe about anything and everything, and that he and Kivat-bat III are on less-than-friendly terms (the former even going so far as to outright insult the latter at times) he cares very much for Kaori's safety and wants to be rid of the Neo-Fangires as much as she does.
Custom Uniform: A bit moreso than Hibari. In his case, alongside the rolled-up sleeves, he wears his tie looser than other students and his jacket tied around his waist in a manner reminiscent of Akane Hino/Cure Sunny.
Dreadful Musician: His dream is to become a rock star. Unfortunately, this trope means that he won't be getting very far...
Hibari: Yo, Wakana-chan... Slow down... I mean, yeah, that kind of thing doesn’t happen everyday, but when it does you should probably take it easy and not act like you’re going through a sugar rush...
The Ghost: Despite being Hibari's father, he rarely makes any appearances other than in photographs. Word of God justifies this as being that he finally made it big as a racecar driver, therefore barely has any free time to visit his newfound family.
Give Her A Normal Life: Well, he certainly wanted this for his daughter, but the Powers That Be said otherwise.
Will Not Tell a Lie: While Sōsuke and Miu have kept their heroic exploits secret from Hibari, Wataru's adherence to this trope meant that he and Saki told Kaori about their pasts much earlier. This inevitably leads to some awkward situations whenever Hibari visits Kaori's family...
However, Wataru has yet to tell his daughter that she's quarter-Fangire.
He also hadn't told her about Mio, his first love, though this was mostly out of forgetfulness than deliberate withholding.
One Note Cook: Her Sweet Tooth was enough to propel her from cake shop employee to owner, but she still can't cook anything else without dumping sugar or other sweets into it. The worst of her efforts usually end up in Wataru's varnish, to her dismay.
Open Minded Parent: Saki is utterly thrilled at the prospect of Kaori becoming an "awesome heroine" like she once was, and even offers her fighting tips. Kaori mostly takes this in stride.
Idol Singer: When she started her career as part of the Girl Group Mettayo☼!!, she was a textbook example of this. Nowadays, her image has become that of a mature and elegant yet quirky woman — more or less like Lady Gaga, but downplaying the "quirky" part — with a more techno-pop style.
