You need to buy this.
It's been a long time since a OP product outside the manga has made me truly happy but here it is at last.
Yellow was a nice touch but the original info was a mere smatter compared to the goldmine that was Blue. Furthermore, Yellow isn't as attractive as a black and white mass of text. But Rainbow is something every OP fan should add to their collection. The biggest sin is that it isn't the size of the Animation Log but its forgivable.
I don't have a lot of time to go over it at the moment, but first a message from Oda included that you HAVE to know. I'm so happy he addressed this and I don't doubt his discussion with Kishimoto at JUMP Festa brought this up. It's regarding Chopper as a mascot character for the series.
Oda reveals that he hates people who create mascot characters. Mascot characters are say, Stitch for Disney (in Japan anyway) Elizabeth for Gintama, Luna for Sailor Moon, Penpen in Eva, etc. Basically cute things made to be turned into toys and merchandise. When Oda created Chopper, he originally designed his snout similar to a regular reindeer. Of all the characters in OP, his was easily the one with the biggest and fastest 'change'. I noticed this when doing the profiles a few years ago and figured he changed his mind. But this turns out to be the real reason.
Oda intended him to be 'cute' in his way of constantly moving ahead no matter what obstacles he faced. Even with the ugly snout, he intended to make him 'cute' by way of his backstory. This is because he was opposed to big glossy-eyed characters designed to sell to the masses. However, the person in charge of animation design at Toei, a Mr. Koizumi, drew an incredibly cute Chopper different from Oda's creation. This began to change Oda's mind. But the wall came down when he heard Otani's voice as Chopper. From that moment his heart changed and he retracted his beliefs on the non-mascot Chopper.
He called the scenario a 'fierce battle' between him and Koizumi but admits the only one who thinks so is just himself.
Anyway, more cool shit when I have time but that stood head and shoulders above everything I've seen thus far.
