Idia Shroud

Dorm: 3rd Year Housewarden of Ignihyde.

The older of the Shroud brothers, a duo considered one of NRC's "Seven Mysteries."

A genius, a shut-in, an "arrogant" otaku, and an unintentionally handsome guy from a prestigious family who harbors a dark side—a man officially described as having the traits of a light novel protagonist. Whether for classes or school events, he generally participates remotely—either communicating via his self-made floating tablet or leaving everything to Ortho to handle. He naturally uses his tablet device even for face-to-face conversations. Notably, he is the only student at the academy permitted to attend classes remotely. He has a limited social circle; aside from Azul (a fellow Board Game Club member) and the Housewardens and Vice Housewardens, he has very few acquaintances.

When encountering people he dislikes or terrifying situations, he lets out strange cries like "Hii!" "Eek!" or "Help me!" while clutching his hands in front of his chest—sometimes even tearing up. However, when faced with a genuine emergency, he utilizes his brilliant mind to calmly assess and handle the situation.

Whether in person or online, if the conversation turns to a topic he is interested in, he comes alive—like a fish in water—and begins speaking enthusiastically, peppering his speech with old-school internet slang. He is harsh toward those who don't understand otaku culture, often muttering, "This is exactly why 'normies' are..." However, if he recognizes someone as a kindred spirit, he is easily won over—to the point where he might end up dancing the night away with a Vice Housewarden from another dorm he barely knows.
