the reason you saw the Ryuki and Blade symbols is that the standby sound for Grand Zi-O's transformation and finisher reuses sounds from previous Riders, and since Ryuki is the first to have voices on his equipament, the fansub skipped the Kuuga and Agito symbols
The red monster guy is called an Imagin(The monster name in Kamen Rider Den O).This one,named Momotaros,helps the main character fight other Imagin(I don't wanna spoil much cuz I kinda wanna see your reaction to what they do in the series when you do watch Kamen Rider Den O) And as you can see,there were also 3 others that float around him.They are also Imagin that help the mc(Yellow = Kintaros,Blue = Urataros,Purple = Ryutaros). Also,they were fighting other Imagins whilst Zio is fighting Another Den O(Another Rider is the monster name in Kamen Rider Zio)
Kamen rider Zi-o is the 20th Heisei Rider series and the closing of the Heisei Era, so he can use the power of the Legend rider. Kuuga is the first Rider in the heisei era And the 10th Rider decade of the Heisei era Because you are fans of Ryuki and Blade, Actor Ryuki and Blade also comeback at Zi-o. Because at Zi-o there are many actors who come back, including Emu and Hiro at Ex-aid. After Japan has changed the empire so it also changes Era, namely a new Era Named "Reiwa" And the first rider in Reiwa was Zero one.
