Actually Boost MK II pushes one of the buttons (and holds it) in order to activate the sounds. Pressing and holding any of the other three buttons (or a Combination) does not seem to activate anything. They could (in theory) make a buckle that also connects Laser Raise Riser, but the gun portion would not make any additional sounds.

In other words, the gun could be involved but there are no additional sounds within the gun for other combinations. Does not mean it can't/won't happen, just that it is not immediately apparent.

So there is a blank sound, then? I previously said there wasn?t because no video review has demonstrated any kind of blank sound, but I?m fully willing to retract that statement if I?m verifiably wrong.

How many episodes will this show have and what will the next season be?

You?ve asked effectively the same question before and been answered repeatedly - at least once by me.

Geats will probably have forty-eight-ish episodes and will likely end in late summer or early autumn. Late August to Early October.

There won?t be any information on what the new series will be until mid-to-late summer, when we start getting real leaks and information on the new rider?s possible cameo in Geats?s Summer Movie. We should get the new show?s name some time in April or May but that?s all until late summer.

It's kind of interesting how despite introducing nearly 20 Riders kn the first 20 or so episodes, there hasn't been a new Rider introduced since Ziin in 22, nearing on 10 episodes ago. (I'm not counting the CGI supporter Riders who only appear transformed in a scene or two)

Didn't Kyuun return?

Are Tycoon and Kekera teaming up in tomorrow’s 2-part episode?

Doesn?t seem to be a Keiwa/Kekera focus next based on the official site, no. I assume we?ll get one eventually.

Something that came to mind.
They confirmed that A/Ace’s original mom is the Goddess, we were also introduced to Sueru, the one who made her such and overall mastermind.
I’m wondering if he is Ace’s original father.

It?s certainly possible, but we don?t really know anything about him yet, other than the fact that he?s the executive producer of the DGP, above Nilam.
