The only problem? Why should I care that Nada is dead?
If you're going to make a character's death impactful, then you must first build up that character to give weight to their loss. And that hasn't happened here. For as many episodes as Nada has been in, he isn't all that well developed, especially since he was only turned good in the previous episode. So there's been no time to learn what heroic Nada is like.
Sentai doesn't kill off heroes very often, and for good reason. So when they do, it's a big deal. Conversely, however, killing off a character is one of the most powerful tools in the writers' chest; it has to be wielded with great care and respect. And that didn't happen here. Instead, the writers have hurt themselves with it.
And stop giving Koh. Every. Single. Power-up!
On a lighter note, I got a good laugh out of Asuna's ping pong serve. Ui's dad congratulating her on completely ignoring the laws of physics was perfectly delivered.
And boy, they really went all-out on the squib packs here. Those last two fights with Uden involved a ton of practical effects, something even the flashier episodes don't necessary do.
Finally, I think I'm more confused than ever about the makeup of the Druidon generals. The chess motif has been apparent since the start. The mooks are the pawns, Tankju was clearly a rook, and meanwhile Uden was obviously a bishop and the other one they named dropped is a queen. But then what are Wiseru and Gachireus supposed to be? The only thing left is the Knight, and for obvious reasons that's reserved for the Ryusoulgers.
I'm confident he'll be back. It's not like Toei to only use a commander suit once, and they've already shown that they will throw logic out the window to bring back the commanders, as we've seen with Tankju and Gachireus.
