Appearance: Idia is a tall young man with pale skin and bright blue, fire-like hair. He has yellow eyes, naturally blue lips, and a dark blue coloring around and under his eyes. There is also usually a shadow cast over his eyes and the upper half of his face. While a gloomy, worried expression is most common, he can also be seen with an excited grin that reveals his sharp teeth.

Idia’s hair is considerably long and reaches down to his knees. While his long bangs fall loosely around his face and between his eyes, the hair on the top of his head seems to flow upwards. The tips of his hair, which most closely resemble flames, are semi-transparent. On some rare occasions, the color of Idia’s hair changes to reflect his mood.[1]

Dorm Uniform As the housewarden, Idia’s dorm uniform somewhat differs from the rest of the Ignihyde students, the few distinguishing features being his padded belt, and several long strips of fabric that trail off of it. The uniform consists of a black textured jacket, a bright blue half-vest, navy-blue pants, and black and blue boots.

The jacket is mainly black with blue underlining. All over the outside of the jacket is a unique, geometric texture, consisting of evenly-arranged triangles. This texture appears to have a metallic shine. The jacket has a large, bright blue collar, resembling that of an aviator jacket, with black lines near the trim. Also along the collar are black zippers that go underneath the jacket. While barely visible, Idia also wears a navy-blue, crew neck shirt under his jacket.

On the right side of his chest is a bright blue half-vest that goes over his right shoulder, and is connected by a blue belt around his torso. The belt has a black triangle pattern and a dark-blue snap buckle, with the long end hanging down to his waist. The half-vest itself has one cargo pocket, above which is a large white button with the symbol of Ignihyde on it.

Just above Idia’s navy-blue pants is a blue padded belt, with a black belt strap and dark blue snap buckle. Hanging from the belt at both hips are blue, box-shaped pouches, with blue squares of fabric behind them, resembling the flaps on a tool belt. Worn over the navy-blue pants around his upper right thigh is a small blue belt with a black triangle pattern and dark-blue snap buckle. Both belts are connected by his black belt strap. Several long strips of fabric fall from the back of Idia’s belt and trail down to his ankles. The fabric’s outer sides are black, while the inner sides are bright blue.

The boots’ design resembles that of thick winter boots. They are mostly black, with bright blue tongues and heel counters. Over the tongues are four bright blue straps with black buckles, and the soles are white.

Personality: Idia is a shy and withdrawn person with a dark outlook on life. Despite his little brother’s suggestions, he prefers to stay in his room at all times, and takes classes remotely whenever possible to avoid interacting with other people. He almost never shows up to ceremonies or housewarden meetings in person, instead using a tablet device to speak from his room.

When in public, Idia can get anxious rather easily. He has a tendency to stutter when speaking with unfamiliar people, so he is sometimes seen using his tablet to communicate.[2] He also seems to be self-conscious about his looks, and is quick to assume that strangers will stare or make fun of him behind his back. In general, he expects a negative outcome from any social situation, so he would rather avoid them altogether.[3]

Despite all of this, Idia acts very differently under certain circumstances. He can talk with people more calmly if he's playing a board game with them[4], or if he's speaking with them over the internet. Moreover, he can speak quickly and enthusiastically about his hobbies or interests, greatly contrasting his usual demeanor. He can also be rather prideful when it comes to his engineering or gaming skills, often considering himself a genius. When he isn't talking to someone face to face, whether it be through a screen or behind a wall, he can speak clearly and quite bluntly. This sometimes backfires on him, though, as he can get a bit confrontational and say things he doesn't mean in the process.[3]

Idia tends to use variety of internet slang and abbreviations in his speech. He also commonly uses video game terms as metaphors for his own experiences.

Trivia: Idia's name likely comes from the greek word «ἴδιος, -α, -ον», meaning 'private, personal, of oneself, reserved'. This could relate to his personality. "Idia" in the initial Greek meaning meant 'one who is removed from politics'. Later coming to mean "idiot". Which some students at NRC tend to see him as. His surname, Shroud, from the Latin word «sudarium», which originally means 'a cloth or handkerchief used to cover the face of dead people, to show them respect', which has relation to the story of Hades (or Pluto) being the God of Death and taking care of the dead. Idia's online nickname is Gloomurai, which is short for Gloomy Samurai.[1] According to Ortho, he has a decent number of fans in certain gaming circles, who tend to copy his in-game fashion sense. Idia has managed to make a few friends over the internet, one of which being someone nicknamed Muscle Red.[7] The two occasionally play video games together. Muscle Red is confirmed later on to be Lilia Vanrouge.[8] However, neither of them seem to be aware of the other's true identity. He has a fondness for cats, as he is once seen baby-talking Trein's cat, Lucius.[9] He once scared Grim to the point of fainting after mistaking him for a cat and attempting to pet him.[7] He also likes dogs, but claims that he can't stand dog people like Crewel.[10] He is apparently good at sketching people from observation.[5] Idia is an avid fan of a three-member idol group called "Precipice Moirai", or "Premo" for short. The group is likely inspired by the three Fates from Hercules. Once, while watching a broadcast of one of Premo's concerts, Idia was caught performing a passionate, cheer-like dance that he calls "glowing".[11] This dance is based on a real practice called "wotagei", and the words used in his cheers are similar to that of a commonly-used wotagei chant. During the school's annual Beanfest, Idia covertly designs and builds high-tech gear to be used by both teams.[12] He gives these to Sam to trade off, and in exchange, Sam lets him hide in the Mystery Shop over the course of the tournament.[13] When trading, Idia goes by the nickname "Mr. Smith" to conceal his identity. In the Japanese version, Idia occasionally uses the pronoun sessha (拙者 or せっしゃ) to refer to himself. This pronoun has gone mostly unused in modern times, but it was used primarily by samurai in the feudal ages. Other times, though, he uses the common pronoun boku (僕 or ぼく). He appears to switch between the two depending on his mood. He is good at singing, often singing anime and game theme songs in his room.[14]

His "past self" aka his overblot is trying to convince him to uh... fuck you but he's trying to ignore it fully aware that you can actually see his overblot self but can't hear him.
