The idol group Hinatazaka46 (previously known as Hiragana Keyakizaka46) had already participated in two seasons of "KeyaBingo", namely the third and fourth one (the third one was thought as a challenge between "Kanji" and "Hiragana", but despite the interesting premise, it turned out quite "meh": whereas the fourth one, all-Hiragana, had been a lot better, imho).
Having changed their name (and separated from the sister group), the Hinatazaka46 girls got their own "Bingo", of which this was the first season.
Except for the V-tubers episode (which, personally, I think nobody older than 10 will find enjoyable, LOL), it was a solid variety show, the cherry-on-top of which was the new MC: I must confess I didn't know Koyabu Kazutoyo at all, so at first I was taken aback by his gruff, borderline rude approach...but it didn't take me long to realize that, behind that curt façade, there's a very nice person - he honestly reminded me a lot of my old Latin & Ancient Greek high school teacher, back at the end of the 80s / beginning of the 90s: he always acted all tough and grumpy, but he had a really great heart and we all missed him dearly, after we graduated!)
