I think that's just the new version of the old 'number theory' stuff.
People noticed that Zero-One was a grasshopper and Saber was a dragon and went "hey, Kuuga was a grasshopper and Agito was a dragon...
clearly this means that they're repeating the Heisei Rider themes with the Reiwa ones!" Then they've spent all of Revice trying (unconvincingly) to find ways that it's "based" on Ryuki, and are insisting that Geats will clearly be related to Faiz and totally prove that they were right all along.
Oh wow I remember the number theory for KR back in the day.
Decade = 1 because of the Rider card (even though decade means 10)
W = 2 Gaia Memories,
OOO = 3 Core medals,
Fourze = 4 Astro switches.
So at this point, there was an ongoing theme with numbers.
Then Wizard = 5 because of 5 fingers smh.
Apparently Gaim = 6 because the lockseeds when opened are shaped like 6.
Drive = 7 because when you flip the shift cars its shaped like 7.
Then Ghost is apparently 8 because the Mugen Eyecon when you flip it on its side = 8 (even though its clearly the infinity symbol).
Ex-Aid = 9 because the Gaashats look like the number 9?
And then with Build it finally all stopped....
Fans are wild, what can I say
. It all ended with Fourze imo.
