So, Nobue is OYAJI. She's kind of like Yukari-sensei, but not in a good way. On the other hand, she also shares traits with Nyamo in that all the little girls like her. Strange, isn't it? Chika is the only serious one. I'd say she's kind of like Yomi. She has her moments, after all. Miyu is kind of like Tomo-chan, just a bit less thoughtful. Imagine that! Matsuri is a mix of Chiyo-chan and Oosaka. Ana also shares some of their traits. Notice there aren't any main male characters?
And so it comes out. Barasui-san _is_ a fan of Azuma-sensei. Why do I think that? See the incriminating evidence below. No wonder there are similarities to his works, although in the end, all I can say is, "nice try, dude!"
Don't be surprised. I just ordered the volume 4 of the manga. Hey, I can still enjoy it with the understanding that I'm reading it as a guilty pleasure.
The incriminating evidence! In case you can't read that, it says Yotsubeto! (sic)
