I have several new hypotheses and (outlandish) speculations.

Hypotheses:
- The face on the Henshin Belt Gavv is actually Dente's face.
- The power-up items for the upgrade form and or final form will likely involve removing the top plate on the Henshin Belt Gavv.
- There could be a Granute police officer who has been going undercover in the human world to investigate Stomach's operation. This Granute police #1 have likely had already become acquainted with Kenzou as a partner in intelligence sharing. This could explain why Kenzou had known way too much about the details of Stomach's operation like I mentioned in episode 4 thread here. This Granute police #1 was also the one who supplied Kenzou with a sample of a Granute's internal organ in episode 6. This Granute police #1 could also be a user of a new transformation device created by Kenzou.
- If Kenzou is indeed backed/supported by a clandestine organization, then this Granute police #1 is likely also acting as a liaison between his police department in the Granute world and Kenzou's organization in the human world.
- There could be another Granute police officer who has been going undercover inside the Stomach corporation. This Granute police #2 is the who has been supplying insider information to Granute police #1.
- Similarly, there could be one or several of Lango's/Stomach's spies inside the Granute police department and or Kenzou's organization who have been tasked with intercepting information about crackdowns.
- If Lango's/Stomach's is serious about protecting his operation, he could've even planted one or several of his spies inside the upper echelons of the Granute police department and or Kenzou's organization and tasked them with spreading disinformation and sabotaging the enemies' operations, or even corrupting and drastically alter the direction of both organizations.
- There could be a lazy Granute who is abusing the reward system by focusing on quantity, not quality, and kidnaps random humans indiscriminately.
- Since this story has made no distinction between happiness, contentment, satisfaction, pleasure, etc, there could be high-quality human targets with completely different situations/back stories, such as:
a man whose wife is just giving birth,
a fresh graduate whose job application has been accepted by his dream employer,
a music composer who has just completed his magnum opus,
a man who has just finished his meal at his favorite restaurant,
a man who has just visited a red light district,
a drug addict who has just had his latest dose,
a disgruntled accountant who has just managed to transfer his boss' money to his bank account,
a scam artist who has just succeeded in defrauding his victims,
a dirty, sleazy politician who has just done an insider trading by manipulating a new bill he helped pass,
etc.
- There could be a financier, or even the financier, who has been financially funding all of Stomach's business ventures, be it the legal or the illegal ones. This financier/ruler could be an outsider, or the supreme member of the Stomach family, who could be Mother Stomach or Grandfather Stomach, which means that there's another member of the Stomach family who has had more authority than Bouche did. Bouche, and now Lango, are the CEO's whose duties is overseeing the day-to-day operation, and this financier/ruler/supreme member is the true owner of the Stomach corporation, aka the invisible hands who is orchestrating the grand design and shaping Stomach corporation's visions, including its political aspirations via Lango. This financier/ruler/supreme member could potentially be the big bad of the story, and, as usual, could very likely transform into a Rider with his/her own Rider system which is being or has been developed by Nyelv.
- Nyelv's main goal is to create the perfect Driver/transformation device which combines the best aspects of Granutes and humans and has the ability to produce Dark Snacks in the most efficient manner, likely as ordered by the financier/ruler of Stomach corporation above. The perfect Driver/transformation device can be considered a miniaturized, portable version of the whole Dark Snack factory.
- The perfect version of Dark Snacks produced by Nyelv's perfect Driver/transformation device could likely be consumed by both Granutes and humans as well, which makes it the perfect way to manipulate both the Granute and human societies.

(Outlandish) speculations:
- Kenzou Suga and Nyelv are the same person, which means that Kenzou is just another one of the human disguises used by Nyelv. This could explain why Nyelv appears right after Kenzou runs away in episode 6 @ 23:34, and also why he possesses the bottom half of Mr. Shioya's Hito Press. Kenzou being Nyelv's alter ego could also explain how Kenzou is able to possess a sample of a Granute's internal organ in episode 6. Nyelv/Kenzou is also the one who's manipulated Mr. Shioya's death in episode 6.
- Nyelv-Kenzou's initial plan was to use KR Valen as sparring partner (aka unknowing pawn) whom he'll gather valuable data from. Now that Shouma/KR Gavv has appeared, Nyelv-Kenzou's planning to also use KR Gavv as his another pawn.
- However, these speculations have too many logical anomalies to even mention.
