Oh, wow, that was quick!

Well uhhhh. Yeah, sweet, glad you're enjoying it! "Kuuga but different and with more style" is definitely an impression that's not surprising. Especially because the precedent of the way Showa Riders did things was still prominent and because Kuuga done pretty well, Agito was in fact originally conceived as just "Kuuga 2". I believe Agito was initially supposed to be an 'evolved' form of Kuuga in a similar way to Black becoming Black RX, and you can certainly see other elements in there too -- the Unknown operating and having a style very similar to the Unidentified Lifeforms; the Police having a massive presence and their having Rider technology feeling like an advancement over what they learned last season; a lot of mystery and ancient mysticism in general... it's all pretty clear. G3 as well is visually very much based on Kuuga himself, and obviously you've got the little direct callbacks to the Unidentified Lifeforms and "No. 4" as your screenshots showed.

That said... it was originally conceived as Kuuga 2, but eventually the concept moved away from that and it was retooled into something different. Many of the same themes and directive choices are still there (such as the heavy involvement of the police and how the Unknowns operate), but eventually the show does start to move away from that and develop its own identity much more solidly.
