The Kids-Bijuu reminds me of Looney Toons xd
I'll applaud Kishi - in the middle of that war, he decided to do a character makeover for the Bijuu who were all "evil" creatures in the beginning. That was a very risky move. Though, the transition was not 100% successful in my eyes; it's not a flop move. To think of it, being able to pass out the emotions of the Bijuus was definitely very hard (writing-wise) cause chaos is reigning everywhere and you'll need to present flashbacks and talking efficient enough so that it turns out plausible. Well, with some cute moments, good build-up, some well-answered parts and some jokes, I must say that he did a pretty good job out of it.
Still, I find it to be an okay chapter. There are some parts which didn't connect as much to me. Perhaps, I preferred if the different Bijuu had more variations in their emotions instead of all being lingering in their pain. I'll give it - 3/5 and hopes that now he's mostly finished to present the Bijuu the way he wants - he get to serious fights.
