This right here.

Shouma appears, and the bubble that pops up next to him in his Rider form. Hanto appears at first next to an empty bubble. Once he becomes a Rider, the bubble depicts his Rider form. The third regular character in the credits appears, and her bubble stays empty for the entire show.

My suspicion is that Sachika was originally intended to be the Rider rounding out the show's trio, specifically as the second Vlaam user, and that her default form was intended to be the hot-pink jelly. For a while after Rakia first appeared, the show was making it pretty clear that Rakia using his hot-pink jelly form's power was jeopardizing his life. Then the show abruptly dropped that whole thread.

If what I suspect is correct, my guess is that Sachika was originally supposed to become Vlaam after Rakia's death, but the actor/character proved popular enough for the show to keep him around (and try to awkwardly shoehorn him into the credits), so the notion of Sachika becoming Vlaam was scrapped.

Pure speculation, of course, but it would fit the discrepancy in the opening credits and the sudden abandonment of the "Rakia's jelly form is damaging his heart" plot.
