Since Sh Ranger brought it up, I’ll point out that Hibiki is the second Rider show to have a theme to its episode titles (namely, when written in Romanji, the first word ends in a “u” sound). The first was Kuuga, who’s theme was that every episode had two syllables in the title (eg. Rebirth). It doesn’t become a regular thing for Kamen Rider until Kiva, after which every season has a theme.

Kiva has the first half of their titles be a music reference, and the second half is a statement relevant to the plot (eg. When the Saints Go Marching In: I will Be King).

Decade has its episode titles in the style of the Rider who he’s teaming up with (eg. The Kuuga team up is Transcendence)

W has its two parters share an overarching title, which is then followed by individual titles, with the overarching title containing a letter relevant to the episode (eg. The W Search, with the W indicating both the main rider and “word”)

OOO’s episodes are in the form of three things relevant to the episode. (Eg. Medals, Underwear and the Mysterious Arm)

Fourze’s titles are 4 syllables, all enunciated. (Eg. Youth! Full! Switch! On!)

Wizard’s titles are written in Kanji and Hiragana (eg. 指輪の魔法使い Yubiwa no Mahōtsukai)

Gaim’s first few episodes insert a fruit (eg. Transform! The Orange from the Sky).

Drive’s episode titles are in the form of a question that gets answered in the episode (eg. Why did my Time Stop?)

Ghost has two short sentences that are filled with exclaim action marks. (Eg. Kaigan! Ore!)

Ex-Aid’s titles are half-Japanese, half-English (eg. Tensai Futari wa No Thank You). Build’s titles are much the same (eg. Best Match no Yatsu ra)

Zi-O’s titles are statements relevant to the episode, followed by a year relevant to the episode (eg. Century King 2068), with episodes focusing on past Riders having that statement be a reference to their show (eg. 555 913 2003). After the halfway point, the year goes first in the title (eg. 2001 Awaken That Soul, 2019 Apocalypse).

Zero-One’s titles are written in katakana and often include a pun (eg. AIなアイツは敵？味方？ AI na Aitsu wa Teki? Mikata?). Episodes beginning a new arc will be titled “I am the x and a Kamen Rider”, with the I being written as “ore” with heroic characters and “watashi” with villainous characters.

Saber’s episodes are referred to as “chapters” and are written in the form of descriptive sentences (eg. In the Beginning, There was a Flame Swordsman).

I’d go into the theme naming for Super Sentai episodes, but then we’d be here all night (and I doubt you have the time or interest for that).
