Idia Shroud

Idia Shroud is a third-year student and the head of Ignihyde, as well as Ortho's "older brother." He is shy and has a dark nature, not wanting to interact with people and staying in his dorm. However, it seems like things are different online.

Appearance
Idia has fiery blue hair which flows down below his waist. He is tall and pale with yellow irises and blue shadow with blue lips. His eye bags and blue lips are natural and not achieved by make-up. He always has a shadow over his eyes. His eyebrows are also generally always worried. He has an attractive face but doesn't realize it.

His hair (which is fire, and so constantly swaying) is transparent at the tips. When his mood drops, the flames weaken. Conversely, when his mood is improved (for example, when he meets a strong energy, or when things go according to his plans), the flames get stronger. This is accompanied by an "evil grin," which he won't show to anybody except someone he is close with.

Personality
Idia doesn't like being in places with many people around and so he doesn't go outside very often. His little brother tried many times to take him outside, but it didn't work. He doesn't talk much with his classmates or people from school, but things change when he talks about his hobby, or things he likes.

As acting captain of S.T.Y.X., he appears to be a reasonable figure in the organization since, unlike his parents, he's not strict and wants to get the work done as soon as possible. After the Charon division captured Yuu, Epel, and Rook, who discovered their hidden location, Idia orders the division to bring them to the Island of Woe alive since he would rather hear them out instead of killing them instantly. According to him, if he wasn't in charge of the organization, Yuu, Epel, and Rook would be dead.

Heritage Curse
{{Spoiler section|The Shroud family curse incinerates blot as it accumulates. Idia has to keep producing blot or else it will consume his magic in order to stay alive. Because of the curse, he will lose the ability to use magic if he can't produce blot or isn't within close proximity of blot in general.

Weaknesses
The Shroud family curse is not immune if they are in an area filled with an overabundance of blot that not even having a support item could offset it, and being dragged to Tartarus and surrounded by a lot of blot is what led to Idia overblotting in Episode 6. }}
