And let's not forget what the Kaixa Driver did before Kusaka took it.

I had already pointed out the crab Granute's sheer stupidity since even the first time he appeared in my post in the episode 13 thread here where he said that it had been much simpler when he was only required by Stomach to kidnap whole humans without Hito Pressing them, and in my post in the episode 14 thread here when he did nothing when Hanto ambushed him (who is in his human disguise) in episode 14 @ 13:31.

This story has sooooooooooooooooooo many stupid characters, be it main characters, side characters, or weekly guest characters, so it's very very very easy to find one, haha. The one who isn't the sharpest tool in the shed is not necessarily the crab Granute, but the writer(s). A story is only as sharp as its author.

The crab Granute's 20 years of experience mainly had to do with kidnapping whole humans, not Hito Pressing humans, since the Hito Press process is a recent innovation, likely only a year or so. That's why the crab Granute's complaining about the Hito Press process making his job harder is just an utterly idiotic statement. Like I elaborated in my post in the episode 4 thread here, any person with common sense knows that the Hito Press process has made the kidnappings much much much easier and more convenient for the Granutes. So, the crab Granute's complaint is just one evidence of how utterly stupid he was, and also a definite proof of how utterly stupid, lazy, cheap, sloppy, convoluted, and heavy-handed Gavv's story is.

TLDR:
Conveniently stupid characters for the sake of moving the plots = Stupid, atrocious story.
