Dajh
At first Dajh's profile said he was 9, but when I read the scenario I got a slightly more childlike image, so I decided to make him a smaller size that you'd just want to pick up and give him a hug, and drew him envisioning him to be 6~7 years old. I expanded on the detail that he liked chocobos which was there from the start, so I decided to make it so that his clothes were bought from a shop focusing on chocobo merchandise. Dajh's favourite is a round emblem with a chocobo motif, the reason being "because it looks a little like the employer's mark on Sazh's shoulder" (laughs). He get his large eyes and hair type from Sazh, but I also imagine that maybe his mouth and small body is from his mother who doesn't appear in the game.
Amoda
For Amoda, I got a suggestion from the scenario writer to "make him just like Kubota (Hideo Kubota: character modelling director/ > P.449)". I was in a different section at the time so I didn't know Kubota, but the instance I actually met him the image came to me. In this game the colouring symbolises the character of the different armed forces, so in contrast to the PSICOM uniforms which are unitarily black, Lightning's Guardian Corps are brighter overall and use more colour. The GC noncommissioned officer (see the righthand page) uniforms were also based on Lightning's outfit. These people show up in the scene in Euride Gorge where they help Dajh.
Rigdy [Rygdea]
Rygdea's body used the same outfit as the members of the Cavalry, I only designed his face. They said that he was a character who couldn't cost much as far as the polygon model or animation went, so I drew a version with short hair as well. But the person in charge of modelling made the long haired version out of enthusiesm for keeping with that design. For his sky blue eyes and auburn hair* I drew upon him being in the Cavalry, who fly around the skies, and gave it the meaning of him being the closest person to the sky. His profile saying he has both a laxness and courage, for example he can be a bit carefree but he has a sharp mind and is skilled at his work, yet he's cheerful and caring, so in keeping with that I tried showing his chest and giving him stubble.
* In Japanese this is トビ色, which means 'black kite colour' referring to the breed of bird, thus the sky imagery.
