Ok so after doing a bit of reading both online and from everyone elses enigma attempts, you say a couple of times that there are some hints on the body AND on the helmet which helps a ton. So let's get started. The crest thingy on the the chest. There are 3 dots with a spike on top. I can only assume that the 3 dots symbolify Amaterasu (The Left Eye) , our guy Tsukuyomi (The Right Eye) and Susanoo (The Nose). Funny thing is, they're literally called the 3 noble children so I'm %99.1 that the crest is a refrence to that. All 3 of them were born when Izanagi washed his eyes and his nose so I assume that the spike symbolifies Izanagi. Also I noticed something a little odd (Not sure if it was intentional) but in the picture of the early development (I'm assuming that's early development) for the chest area, he doesn't have the crest. I'm just going to assume that's intentional so yeah haha. Now on each of their chins there's this sort of "U" shape with lines over them. But weird enough is that in one picture blue has 3 line and in another has 1. And even weirder is that red has the exact same lines in each picture that being 3. That's the only thing that really looked like it could be a hint. Either that or I am not good at looking for hidden symbols lol. Now what they could mean I don't know or they might mean nothing at all. But anyways always fun to take another swing at this! I hope to god someone gets it right so I can see where I went wrong xD
