* ActorAllusion: The final episode features cameos by Kazuo Niibori and Naoki Ofuji, the suit actors for Red Hawk and Black Condor, as [[spoiler:the priest who conducts Ryu's wedding with Kaori and the mugger who stabs Gai respectively]].
** It's also FridgeBrilliance.
* TheDanza: Kaori's prehistoric counterpart in episode 26 is called Rika, just like the actress playing her.
* NamesTheSame No, the Blue Swallow Hotel isn't named after Ako.
* PeripheryDemographic; J-drama magazines of the time had coverage of Jetman, something not seen before or since from a Sentai.
* WhatCouldHaveBeen: A [[http://henshingrid.blogspot.com/2010/11/mecha-early-designs-and-scrapped-ideas.html Super Sentai art book]] showed that they were gonna have a giant, heavily armed fortress robot, like in ''Turboranger'' and ''Fiveman'', but didn't go through with it (from the sketches, it would've been a retooled version of the Turborangers' Turbobuilder).
