I watched the clipping and both of them gave me a good impression

Some funny moments are when Manaha said she loves winter, appearead a comment where Gussan said he hates it w (8. 35 of the video)
Some moments later, made me laugh Manaha's attempt to guess Kawabata-san nickname, naming him Mr. December
Kinda cute the difference between them about where they like to stay the most (indoor or outdoor)
At 17.45, another comment named the two newbies Mao and Mana-chan, I would do the same (from now on, I'll call Manaha like that or simply Mana)
That made me curios about their emote signature (maybe Mao will be a cat, because her name sounds kinda like meow in English?
I doubt about that, but it would be fun)
At the end, on the video's comment section, the first oned noticed the fact Mana, the day before, was still working for 福井ニユース

About voices, I agree with you, though Mana's voice is not that bad
About their first shift, it will be splitted up in two (has almost always been like that)
