WHAT DO YOU MEAN HIS LIPS ARE NATURALLY BLUE?!! - Tumblr Posts

hello is there any more canon facts about Idia said outside the game (ex: in an interview with Yana Toboso or Disney, some translated or unused facts etc….)

Hello hello! ^^ Thank you for this question!

Yes yes, here is a translation of illustration comments from Yana, found in the Magical Archives Game Guide (2020)

・"The flames of his hair become weaker when he loses interest in something."

・"Compared to the other villains Hades is quite a comical character, so I think that it would be good for Idia to be very expressive."

・"The bags under his eyes and the blue of his lips are not make up, but entirely natural. His eyebrows always make him look troubled. His hair is flames, so it is always moving, and the ends are translucent. His eyes are always shaded. He has a well-defined face, but he is not aware of it."

・"He makes this expression sometimes when he gets excited. Like when he comes across a strong enemy in a video game, or when things are going according to plan. Most people won’t see this look at first, until he’s grown close to them."

About Ignihyde's dorm uniform (also from the game guide)

"The dorm uniform’s theme is artificial and high-tech. I kept out as much warmth from the design as I could. The jacket is made of pieces of enamel, and was inspired by the triangular pattern of Hades' clothing.

There is a pouch worn around the waist that can hold plenty of tools and batteries. The housewarden has a belt that hangs loosely from the pouch down to his feet, to represent the smoke that rises up from Hades’ feet when he walks. The one-shoulder vest was inspired by the ancient Greek toga."

There are no particular Idia references of note in any of the visual books or the Design Note ^^

And we know from Yana's Twitter that Idia was originally meant to have been the youngest character on the main cast! Yana says that he is the reason why NRC allows grade-skipping.

(Despite how there are no underage characters on the main cast Trey has a line of "we do get some child prodigies here," in Book 1. This was possibly meant to explain how Idia was able to enroll, going unchanged after Idia was aged up for the final version of the game.)
